Earth is the only planet we know of in our solar system that humans can live on. No other planet has oceans, other life forms, and enough oxygen to comfortably breathe. Because we have so much water, Earth is called the Blue Planet. From space the oceans combined with the atmosphere makes the planet look blue.
Earth - What It's All About
About 71 per cent of the Earth is covered with water. Earth is the only planet where water can exist in liquid form on the surface. Even though we have water coming out of our ears, only one percent of it is drinkable. Most of it is frozen or salty. Earth is the fifth largest planet and the third planet from the Sun with only Mercury and Venus being closer. It's about 24,920 miles around Earth at the equator. That means it would take 33,000,000 people holding hands to reach all the way around. The land on Earth is made of several plates and at one time all of these plates were joined together, making it possible to walk from one side of the Earth to the other. Plates are individual pieces that are always moving so the land keeps drifting apart slowly. Today there are seven distinct land masses known as continents.
Earth - Fun Facts
- A thousand tons of meteor dust falls to Earth every day.
- Only 11 percent of the Earth's surface is used to grow food.
- Wind carries over 100 million tons of sand grains around the Earth every year. That means if you live in the United States, you could have sand from the Gobie desert in China reach you.
- Antarctica is the coldest place on Earth. The entire continent is made of ice.
Save the Forest
The evolution of people and animals was only possible because of plants. Plants are the base of the food chain and the source of energy for almost all life on Earth. Forests are ancient, mature communities of plants and animals, with homes and places for thousands of species. Forests give us oxygen, food, shelter, medicines, fuel, and furniture. Forests protect us from the heat of the sun, and from wind, cold, and rain. Forests maintain the balance of nature, the environment, the climate, the weather, and the composition of the atmosphere. As a matter of fact, forests are our life. But what are we doing? We are destroying the forests, meaning we are destroying our life and our future. All the problems we face today are made worse by deforestation. If we are thinking beings, we must save plants and forests, because they save us.
Save the Wildlife
We can’t say the Earth belongs to humans; living things were using it for billions of years, before our own species showed up just some five million years ago. Our Earth belongs to all living things, if it belongs to any of them. But we overpowered many species and killed them for our use. Now thousands of species are extinct because their habitat is gone. As a matter of fact, these animals, birds, and insects have actually built a better environment for us, provided us with so many things: they are not just creatures, but the real creators of nature. We are here on Earth because they are here on Earth. If they are gone, we will also be gone. So the only wise thing to do is to save wildlife and its habitat.
Save the Environment
Through deforestation, urbanization, industrialization, and pollution, our environment is being destroyed. Flows of energy, nutrients, and other elements are disrupted. Global warming and climate change are the major threats to Earth and all human beings. Due to carbon dioxide and other greenhouse gases emitted by civilization, heat is building up in the atmosphere at a rate not seen for tens of millions of years. The cities are becoming “heat islands.” Pollution is becoming a great killer. Levels of air pollution, water pollution, noise pollution, and food contamination are high. Human interference has brought nature close to destruction. Now we all must come together to prevent pollution and save the environment and humankind.
