Original text of "Only One Earth" primary school textbook

According to astronauts who were lucky enough to fly into space, when they looked at the Earth from afar while flying in the sky, what they saw was a crystal clear sphere. , with blue and white lines intertwined with each other, surrounded by a thin layer of aqua blue "gauze". The earth, the mother of mankind, the cradle of life, is so beautiful, spectacular, and amiable. However, the earth is a planet with a radius of only more than 6,300 kilometers. In the universe of bright stars, it is like a small boat.

Compared with the vast universe, the earth is small. It is only this big and will not grow any larger. The earth's surface area is 510 million square kilometers, and the land where humans live only accounts for about one-fifth of it. In this way, the scope of human activities is very small.

The earth’s natural resources are also limited. Take mineral resources as an example. They are not a gift from God, but are formed after millions or even hundreds of millions of years of geological changes. The earth is selfless and generously provides mineral resources to mankind. However, if mining is carried out without restraint, the mineral resources on the earth will become less and less.

The water resources, forest resources, biological resources, and atmospheric resources needed for human life can be continuously regenerated and contribute to mankind in the long term. However, human beings destroy natural resources at will and abuse chemicals regardless of the consequences, which not only makes them unable to regenerate, but also causes a series of ecological disasters, posing a serious threat to human survival.

Some people will say, isn’t the universe very big? There are countless planets there. When the earth’s resources are exhausted, can’t we move to other planets?

Scientists have proven that there is no second planet suitable for human habitation, at least within a range of 40 trillion kilometers centered on the Earth. Human beings cannot expect to move to other planets after destroying the earth.

Yes, scientists have put forward many ideas, such as building immigration bases on Mars or the moon. However, even if these ideas come true, they are still far away. Besides, how many people can live there?

"Our earth is so cute, but at the same time it is too easily broken!" This is the sigh of astronauts when they travel in space and see the earth.

There is only one Earth, and if it is destroyed, we have nowhere to go. If all kinds of resources on the earth are exhausted, it will be difficult for us to replenish them from other places. We must carefully protect the earth and its ecological environment. Let the earth better benefit our descendants!
