The original text is as follows:

According to the astronauts who were fortunate enough to fly into space, they looked at the earth from afar as they traveled in the sky, and what caught people's eyes was a crystal 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 and magnificent, so amiable.

However, in the starry universe, the Earth is a planet with a radius of about 6,400 kilometers. Compared to the vast universe, the earth is small. It's only so big that it won't grow again.

The natural resources that the earth has are also limited. In the case of mineral resources, it is not a gift from anyone, but has been formed after millions or even hundreds of millions of years of geological changes. The earth is altruistic, and it generously provides mineral resources to humanity.

However, if it is not exploited in moderation, it will accelerate the depletion of the earth's mineral resources.

Water resources, land resources, and biological resources, which are needed for human life, can be continuously regenerated and contribute to mankind in the long run. However, because people destroy natural resources indiscriminately and recklessly abuse chemicals, they not only make them non-renewable, but also cause a series of ecological disasters, which pose a serious threat to human survival.

Some people will say, isn't the universe very big, there are countless planets, and 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 the forty trillion kilometers centered on the Earth. Humanity cannot expect the destruction of the Earth and then the relocation to another planet.

Yes, scientists have come up with many ideas, such as building colonization bases on Mars or the Moon. But even if these ideas are realized, they are far away. Besides, how many people will be able to live there?

Our earth is so lovely, and at the same time too easily broken! This is the exclamation of astronauts when they travel to space and see the earth.

There is only one Earth, and if it is destroyed, we have nowhere else to go. If the planet's resources are depleted, it will be difficult for us to replenish them from elsewhere. We must carefully protect the earth and protect the earth's ecological environment.

Let the planet be better for our children and grandchildren!
