Have you think how large are our solar system, or maybe our galaxy, the Milky Way ? Of course they are very large, right? How if we compare them with our earth. The earth is really small, it is as small as a sand particle compared with the Milky Way that as big as a large island. And the earth is as small as a marble compared with the solar system.
The earth is a tiny part of the universe, but the earth is really precious. Only in the earth a life system can be found until now. The other planets cannot support a life, because of their extreme characteristics or the lacks of oxygen.
But why some peoples in the earth don't care about the earth? Don't they know that the earth is only one? I don't talk about the other persons, I talk about our self. Sometimes we didn't care about nature, in the other word, the earth. For example, we littering and pollutes our environment. We don't know what will happen if we do that, or we know but we ignored it. We know that littering will cause a bad looking for our live place, bad smell, or even a flood and disease. The illegal logging and non-environmentally friendly also take a great part of the natural damage.
So, what should we do?
We can make a reforestation, but it is really hard, right? My teacher say that we can plant a tree for every birthday. It is simple but so effective. We can make our environment become fresh too. The other way is to stop using AC (air conditioner) and perfume that uses CFC or the other ozone damaging gas.
Why we don't start from now?
