What is the content material of garbage classification?

There are four kinds of garbage: recyclable garbage, harmful waste, kitchen waste and other garbage. Many of my brothers and sisters can turn waste into treasure if everyone sorts out the rubbish when they throw it away.

For example, five plastic bottles can be made into a fiber garment after scientific processing. However, sometimes people will accidentally divide the garbage wrong, and we will be very sad and disappointed; Because of the wrong garbage, we have to sort, burn and bury it again, and finally disappear into this world.

With the country's land resources becoming less and less, there are only a handful of garbage dumps that can be used. You can imagine this picture: garbage piles up into mountains, and human beings are surrounded by garbage and have no place to stand.

The significance of protecting the environment:

People live in the natural environment, which is the basic condition for human survival and the material source for developing production and prospering economy. Without the vast natural environment of the earth, it is impossible for human beings to survive and reproduce. With the rapid growth of population, the development of productivity and the rapid development of science and technology, more and more wastes are discharged from industry and life.

As a result, air, water and soil pollution are becoming more and more serious, the natural ecological balance is seriously impacted and destroyed, and many resources are decreasing day by day, facing the danger of exhaustion. Soil erosion and land desertification are becoming more and more serious, and food production and human health are seriously threatened. Therefore, maintaining ecological balance and protecting the environment are fundamental issues related to human survival and social development.
