How to protect flowers and trees

Sixth grade environmental protection composition: it is urgent to protect our home.

With the change of the times, people pay less and less attention to the living environment, destroy forests and cut down a lot of trees. This practice is very wrong. Without trees, we can't live, because as we all know, flowers, trees and people need to breathe. People need 0.75 kg of oxygen and release 0.9 kg of carbon dioxide every day, but plants are just the opposite. Through photosynthesis, an acre of trees can "make" 94 kilograms of oxygen and "recycle" 67 kilograms of carbon dioxide every day. Plants can not only purify the air, but also filter dust. In some cities, the annual dustfall per square kilometer reaches 500 tons, and some even reach 1000 tons. Green leaves can keep the dust in the air under the leaves, which is really a well-deserved air "filter".

Let's plant trees together! Trees are very helpful to our environment. If everyone in the world plants a tree, the whole earth will become an ocean of trees and the air of human beings will be very fresh. If the trees really go on like this, maybe in a few decades, our beautiful earth will become a bare "bad old man". What should our future generations do?

Moreover, water is the cradle of life, and no life on earth can be separated from water. The water resources on the earth are limited, but for a long time, people only know how to use them, but they don't know how to cherish them, even pollute and destroy precious water resources, making the water resources available for human use increasingly scarce. Take Puyang River here as an example. At first, its water was very clean, but now it is polluted, so it must be extracted from the Cai Chen Reservoir far away.

It can be seen how important greening and environmental protection are.
