We do not have any other known planet beside earth in this universe where life is possible. It is the only known planet where the combination of most essential natural resources oxygen, water and gravity is found which makes the possibility of successful life here. We do not have time to think more about it and start saving earth seriously by following various effective measures in order to handover a healthy earth to our future generations. People should plant more trees to get sufficient oxygen and curb the effect of air pollution and global warming.

We should stop cutting down rain-forests to our life, atmosphere and homes of many different species. People should limit their use of electricity and use less fossil fuel to save the environment from global warming. They should promote the use of solar lights and wind energy to save destroying earth. Following the 3R rule (Reduce, Reuse, Recycle) can be proved very effective in saving our precious earth.

Save Earth Essay 3 (200 words)

Earth is the most precious thing in this universe having oxygen and water, essential things for life. The natural resources found on earth are deteriorating day by day because of various wrong practices of human beings. It keeps life on earth in danger. Various forest animals have been extinct completely because of the lack of their favorable environment.

The rate of various types of pollution, global warming and other environmental issues is increasing day by day. It is very necessary to stop all the bad practices to reduce the negative effects of same. Earth day is celebrated every year on 22nd of April to spread awareness among people all over the world. It is observed annually to appreciate people to maintain the earth’s natural environment.

Our earth takes nothing in return from us however it demands to maintain it for the continuity of health life on earth. We are not alone to live on the earth; there are various unknown living species that live on earth.

So, we should not be selfish and think about all the living species on the earth. We should save our earth and environment by reducing the amount of wastes, plastic, paper, woods, etc. we should make the habit of reuse and recycle things (clothes, toys, furniture, books, papers, etc) in order to generate less waste. We should stop all the bad practices involved in increasing the level of pollution and global warming.

Save Earth Essay 4 (250 words)

The present condition of the earth has been very challenging for the healthy existence of life because of the toxic environment, air pollution, water pollution, global warming, deforestation, and many more environmental issues. There are numerous easy ways we can save our planet however, depends on the dedication and rate of good habit followers. It should be promoted the development of environment friendly technologies so that they could not harm the planet. People should make the habit of reduction in usage of harmful things, re-usage and recycle of things in order to generate less amount of wastes.

Generally, many people use variety of house cleansers in order to keep their houses clean and disinfected. They never see the chemical constituents of that particular cleanser which can be very destructive to the water, soil and air. We should be very clear about what products we are using in daily life and always select eco-friendly cleansing products. Pollutions and global warming are generally being spread by the commercial industries to a great extent. They should follow the government rules and regulations made for controlling the same.

They should limit their harmful commercial-grade production and involve in producing environment friendly products. Awareness regarding save earth should be promoted among youths by including this topic to their study. They should be involved in the activities like planting, group discussion, essay writing, speech recitation, banner making, slogan writing competition, theme based drama play, etc in the school and college. The event named as Earth Day is celebrated annually on 22nd of April to spread awareness regarding save earth among public.

Earth is the only known planet in this universe where life is possible as it has basic necessities of life. We need to maintain the natural quality of our mother earth in order to continue the healthy life here. Save earth save environment and save earth save life are the most famous slogans to increase awareness about save earth among people. There are various means the condition of our earth is getting declined day by day due to the pollution, greenhouse gases, etc. It is generating the harmful impact on environment and thus health of people. It is the responsibility of human beings to keep earth safe, clean and natural.

What is Earth Day

Earth Day is a global annual observance celebrated on 22nd of April since 1970 to protect the environment and save earth. The aim of this event is to inspire people for healthy earth’s environment.

How to Save our Earth

Following are some easy and effective ways of saving earth:

  • We should not waste water and use only according to the requirement. We should wash dirty clothes only and in the cold water. In this way, we can save many gallons of water per day.
  • People should share private cars and generally use public transport in order to reduce the emission of greenhouse gases.
  • People should use bicycle to perform work in local areas.
  • People should follow 3R methods means reduce, reuse and recycle things.
  • People should make compost which is a great natural fertilizer for the crops.
  • We should use Compact fluorescent light bulbs (CFLs) instead of common bulbs as they are more durable and use two-third less energy which will reduce the use of electricity and greenhouse gases emissions.
  • We should not use electric heater or air conditioner unnecessarily without necessity.
  • We should maintain our private transport and drive smartly in order to reduce pollution.
  • We should switch off lights, fans and unplug other electric appliances to use less electricity.
  • We should plant more trees in the surrounding areas to reduce pollution and effect of green house gases.


Earth is our mother planet which gives us all the necessary things we need for living a life. So, we are also responsible to maintain its natural quality and greenery environment. We should not waste and pollute its natural resources for our small benefits.


Save Earth Essay 6 (400 words)


Save earth and save environment both related to the safety of life on the earth. As being human being, we should strictly involve in the activities reducing pollution and global warming and save the earth.

Easy Ways to Save Earth

There are various easy ways which can be helpful in saving the earth. Earth is the only known planet of the solar system having life. In the ancient time, people were not involved in any type of destructive work, so there was no any fear of pollution and other environmental issues. After explosion in the population, people started developing cities and industries for the modern lifestyle and easy life for everyone. For industrialization man learned misusing the natural resources beyond the limit. People involved in deforestation which resulted in extinction of various wild animals, pollution, and global warming. Due to the global warming the protective ozone layer got a hole, rise in sea level, melting of ice caps of Antarctica and Greenland, etc negative changes occurred. Such types of environmental changes are alarming sign to us. Following are some ways regarding save earth:

  • We should save forest through afforestation and reforestation. Plants are the most basic need of life whether human beings, animals or other living things. They give us food, oxygen, shelter, fuel, medicines, safety, and furniture. They are very necessary to maintain the natural balance between environment, climate, weather, and atmosphere.
  • We should take care of the wildlife by stopping deforestation and promoting reforestation. Thousands of species and birds have been extinct because of destruction of their habitat. They are very necessary to balance the food chain in the nature.
  • Our environment is being declined continuously as a result of deforestation, industrialization, urbanization, and pollution. It is threatening the lives through global warming and climate changes because of the emission of carbon dioxide and other greenhouse gases. We should save our environment to balance all the natural cycles.
  • We are needed to bring huge level changes in our unnatural lifestyle as much as possible to save the earth.
  • There is need to transform cities into Eco-cities to maintain the ecological balance in the atmosphere.
  • The government of all the countries need to work together to bring global changes.

Why to Save Earth

There is urgent need to save our earth because of the continuous rising in global temperature, melting of polar ice caps, bleaching of coral reefs, and increasing risks of tsunami, floods and droughts. The condition of our mother earth is getting poor which is reducing the chances of healthy life. Earth is the most important source of all the basic elements required to keep us alive. Bad human activities have given rise to various environmental issues due to release of toxic fumes, chemical wastes and excessive noise.


Government has taken various effective steps regarding save earth, save life and save earth, save environment in order to continue the healthy life on the earth. Without earth, life is not possible anywhere in the universe. Human activities related to the destruction of natural resources of earth are impacting the earth environment very badly. So, it is our sole responsibility to save the earth by practicing Eco-friendly activities.

Earth is the planet we live on. It is the third planet from the sun. It is the only planet known to have life on it. Lots of scientists think the earth formed around 4.5 billion years ago.[5] It is one of four rocky planets on the inside of the Solar System. The other three are Mercury, Venus and Mars.

The large mass of the sun makes Earth move around it, just as the mass of Earth makes the moon move around it. Earth also turns around in space, so that different parts face the sun at different times. Earth goes around the sun once (one "year") for every 365¼ times it turns all the way around (one "day").

Earth is the only planet in our solar system that has a large amount of liquidwater.[6] About 71% of the surface of Earth is covered by oceans. Because of this, people sometimes call it "blue planet".[7]

Because of its water, Earth is home to millions of species of plants and animals.[8][9] The things that live on Earth have changed its surface greatly. For example, early cyanobacteria changed the air and gave it oxygen. The living part of Earth's surface is called the "biosphere".[10]

Orbit and turning[change | change source]

Earth is part of the eight planets and many thousands of small bodies that move around the Sun as its solar system. The Solar System is moving through the Orion Arm of the Milky Waygalaxy now, and will be for about the next 10,000 years.[11]

Earth is generally 150,000,000 kilometers or 93,000,000 miles away from the sun (this distance is named an "Astronomical Unit"). Earth moves along its way at an average speed of about 30 km or 19 mi a second.[12] Earth turns all the way around about 365¼ times in the time it takes for Earth to go all the way around the sun.[13] To make up this extra bit of a day every year, an additional day is used every four years. This is named a "leap year".

The Moon goes around Earth at an average distance of 400,000 kilometers (250,000 mi). It is locked to Earth, so that it always has the same half facing Earth; the other half is called the "dark side of the moon". It takes about 27⅓ days for the Moon to go all the way around Earth, but because Earth is moving around the Sun at the same time, it takes about 29½ days for the Moon to go from dark to bright to dark again. This is where the word "month" came from, even though most months now have 30 or 31 days.

History of Earth[change | change source]

See also: Historical geology, Age of the Earth, Giant impact hypothesis, and Great Oxygenation Event

Earth and the other planets formed about 4.6 billion years ago.[14][15] They were made of the leftover gas from the nebula that made the Sun. The Moon may have been formed after a collision between the early Earth and a smaller planet (sometimes called Theia). Scientists believe that parts of both planets broke off — becoming (by gravity) the Moon.[16]

Earth's water came from different places. Condensingwater vapour, and comets and asteroids hitting Earth, made the oceans. Within a billion years (that is at about 3.6 billion years ago) the first lifeevolved, in the Archaeanera.[17] Some bacteria developed photosynthesis, which lets plants make food from the Sun's light and water. This released a lot of oxygen, which was first taken up by iron in solution. Eventually, free oxygen got into the atmosphere or air, making Earth's surface suitable for aerobic life (see Great Oxygenation Event). This oxygen also formed the ozonelayer which protects Earth's surface from bad ultravioletradiation from the Sun. Complex life on the surface of the land did not exist before the ozone layer.

Earth was very different in the distant past. Long ago, almost all land was in one place. This is called a supercontinent. The earliest known supercontinent was called Vaalbara. Much later, there was a time (the Cryogenian) when Earth was almost entirely covered by thick ice sheets (glaciers).[18] This is called the Snowball Earththeory.[18]

What it is made of[change | change source]

Earth is rocky. It is the largest of the rocky planets moving around the sun by mass and by size. It is much smaller than the gas giants such as Jupiter.

Chemical make-up[change | change source]

Overall, Earth is made of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%). The 1.2% left over is made of many different kinds of other chemicals. Chemicals that are very uncommon (such as gold and platinum) can be very valuable.

The structure of Earth changes from the inside to the outside. The center of earth (Earth's core) is mostly iron (88.8%), nickel (5.8%), sulfur (4.5%), and less than 1% other things.[19] The Earth's crust is largely oxygen (47%). Oxygen is normally a gas but it can join with other chemicals to make compounds like water and rocks. 99.22% of rocks have oxygen in them. The most common oxygen-having rocks are silica (made with silicon), alumina (made with aluminium), rust (made with iron), lime (made with calcium), magnesia (made with magnesium), potash (made with potassium), and sodium oxide, and there are others as well.[20]

Shape[change | change source]

Earth's shape is a spheroid: not quite a sphere because it is slightly squashed on the top and bottom. The shape is called an oblate spheroid. As Earth spins around itself, the centrifugal force forces the equator out a little and pulls the poles in a little. The equator, around the middle of Earth's surface, is about 40,075 kilometers or 24,900 miles long.

The highest mountain above sea level—the well-known Mount Everest (which is 8.8 km or 5.5 mi above sea level)—is not actually the one that is the farthest away from the center of the Earth. Instead, the sleeping volcanoMount Chimborazo in Ecuador is; it is only 6.3 km or 3.9 mi above sea level but it is almost at the equator. Because of this, Mount Chimborazo is 6,384.4 km or 3,967.1 mi from the center of the Earth, while Mount Everest is 2.1 kilometers or 1.3 miles closer to it.[21][22][23] Similarly, the lowest point below sea level that we are conscious of is the Challenger Deep in the Mariana Trench in the Pacific Ocean. It is about 10.9 km or 6.8 mi below sea level,[24] but, again, there are probably places at the bottom of the Arctic Ocean that are nearer to the center of the Earth.

The deepest hole ever dug is only about 12.3 kilometers or 7.6 miles. We know something about the inside of the Earth, though, because we can learn things from earthquakes and the times when volcanoeserupt. We are able to see how quickly the shock waves move through Earth in different places.

The inside of Earth is very different from the outside. Almost all of Earth's liquid water is in the seas or close to the surface. The surface also has a lot of oxygen, which comes from plants. Small and simple kinds of life can live far under the surface, but animals and plants only live on the surface or in the seas. The rocks on the surface of Earth (Earth's crust) are well known. They are thicker where there is land, between 30 to 50 km or 19 to 31 mi thick. Under the seas they are sometimes only 6 km or 3.7 mi thick.[25] There are three groups of rocks that make up most of the Earth's crust. Some rock is made when the hot liquid rock comes from inside the earth (igneous rocks); another type of rock is made when sediment is laid down, usually under the sea (sedimentary rocks); and a third kind of rock is made when the other two are changed by very high temperature or pressure (metamorphic rocks). A very few rocks also fall out of the sky (meteorites).

Below the crust is warm and almost-liquid rock that is always moving around (the Earth's mantle). Then, there is a thin liquid layer of heated rock (the outer core). This is very hot: 7,000 °C or 13,000 °F.[26] The middle of the inside of the Earth would be liquid as well but all the weight of the rock above it pushes it back into being solid. This solid middle part (the inner core) is almost all iron. This is what makes the Earth magnetic.

Pieces of the crust form plates[change | change source]

Main article: Plate tectonics

The Earth's crust is solid but made of parts which move very slowly.[27] The thin level of hard rock on the outside of the Earth rests on hot liquid material below it in the deeper mantle.[28] This liquid material moves because it gets heat from the hot center of the earth. The slow movement of the plates is what causes earthquakes, volcanoes and large groups of mountains on the Earth.

There are three ways plates can come together. Two plates can move towards each other ("convergent" plate edges). This can form islands (such as Japan), volcanoes, and high mountain ranges (such as the Andes and Himalayas).[29] Two plates can move away from each other ("divergent" plate edges). This gives the warm liquid rock inside the earth a place to come out. This makes special mountain ranges below the sea or large low lands like Africa's Great Rift Valley.[30][31] Plates are able to move beside each other as well ("transform" plate edges, such as the San Andreas Fault). This makes their edges crush against each other and makes many shocks as they move.[32]

Surface[change | change source]

The outside of the Earth is not even. There are high places called mountains, and high flat places called plateaus. There are low places called valleys and canyons. For the most part, moving air and water from the sky and seasdamages rocks in high places and breaks them into small pieces. The air and water then move these pieces to lower places. Because of this, the Earth would have been very flat a long time before now. The fundamental cause of the differences in the Earth's surface is plate tectonics.

All places on Earth are made of, or are on top of, rocks. The outside of the Earth is usually not uncovered rock. Over 70% of the Earth is covered by seas full of salty water.[33] This salty water makes up about 97½% of all Earth's water. The fresh water people can drink is mostly ice. Only a very small amount is in rivers and under the Earth for people to drink and use.[34] The air above the Earth stops the water from going away into outer space. Also, much of the land on Earth is covered with plants, or with what is left from earlier living things. Places with very little rain are dry wastes called deserts. Deserts usually have few living things, but life is able to grow very quickly when these wastes have rainfall. Places with large amounts of rain may be large woods. Lately, people have changed the environment of the Earth a great deal.

Air[change | change source]

Main article: Atmosphere

All around the Earth is a large amount of air (the atmosphere). The mass of the Earth pulls the gasses in the air down and does not let them go into outer space. The air is mostly made of nitrogen (about 78%) and oxygen (about 21%) but there are a few other gasses as well.[35] Most living things need the air (or parts of the air gripped in the water) to breathe and live. They use the gasses—especially oxygen and carbon dioxide—to make and use sugar and to give themselves power.

The air animals and plants use to live is only the first level of the air around the Earth (the troposphere). The day to day changes in this level of air are named weather; the changes between places far away from each other and from year to year are named the climate. Rain and storms are both in this level. Both come about because this part of the air gets colder as it goes up. Cold air becomes thicker and falls, and warm air becomes thinner and goes up.[36] The turning Earth moves the air as well and air moves north and south because the middle of the Earth generally gets more power from the Sun and is warmer than the north and south points. At the same time, air over water (specially very warm water) gets water in it but, because cold air is not able to take in as much water, it starts to make clouds and rain as it gets colder. The way water moves around in a circle like this is called the water cycle.[36]

Above this first level, there are four other levels. The air gets colder as it goes up in the first level; in the second level (the stratosphere), the air gets warmer as it goes up. This level has a special kind of oxygen called ozone. The ozone in this air keeps living things safe from damaging rays from the Sun. The power from these rays is what makes this level warmer and warmer. The middle level (the mesosphere) gets colder and colder with height; the fourth level (the thermosphere) gets warmer and warmer; and the last level (the exosphere) is almost outer space and has very little air at all. It reaches about half the way to the Moon. The three outer levels have a lot of electric power moving through them; this is called the ionosphere and is important for radio and other electric waves in the air. It is also where the Northern Lights are.

Even though air seems very light, the weight of all of the air above the outside of the Earth (air pressure) is important. Generally, from sea level to the top of the outer level of the air, a space of air one square centimeter across has a mass of about 1.03 kg and a space of air one square inch across has a weight of about 14.7 pounds. The mass of the air also keeps the Earth safe when rocks (meteorites) hit it from outer space. Without the air, the damage meteorites do would be much greater. Because of the air, meteorites generally burn up long before they get to the earth.

The air also keeps the Earth warm, specially the half turned away from the Sun. Some gasses – especially methane and carbon dioxide – work like a blanket to keep things warm.[37]In the past, the Earth has been much warmer and much colder than it is now. Since people have grown used to the heat we have now, though, we do not want the Earth to be too much warmer or colder. Most of the ways people create electric power use burning kinds of carbon—especially coal, oil, and natural gas. Burning these creates new carbon dioxide and can cause more warming. A large discussion is going on now about what people should do about the Earth's latest warming, which has gone on for about 150 years. So far, this warming has been good for people: plants have grown better and the weather has been better than when it was colder before. Some people who learn about science, though, say that many bad things will possibly come about if the warming goes on.

People[change | change source]

Main article: Human

About seven billion people live on Earth. They live in about 200 different lands called countries. Some (like Russia) are large with many large cities. Others (like the Vatican) are small. The five countries with the most people are China, India, the United States, Indonesia, and Brazil. About 90% of people live in the north half of the world, which has most of the land. Scientists think that people originally came from Africa. Now, 70% of all people do not live in Africa but in Europe and Asia.[38]

People change the Earth in many ways. They have been able to grow plants for food and clothes for about ten thousand years. When there was enough food, they were able to build towns and cities. Near these places, men and women were able to change rivers, bring water to farms, and stop floods (rising water) from coming over their land. People found useful animals and bred them so they were easier to keep.
