Now the earth is all yellow, and the green is greatly reduced. What happened? It turns out that this is because people cut down a lot of trees, which not only makes birds lose their homes, but also causes collapses and floods. Without trees, our earth seems to have no pillars.

Now all the shops are following our hobby, producing a lot of soft drinks. The "coat" of soft drinks is canned, which is a kind of pollution. Roads, parks and even schools have become their homes. Some cans are made of aluminum, which is also harmful to human body.

Do you know that?/You know what? Do you know that?/You know what? Waste batteries contain a lot of heavy metal pollutants-chromium, lead, mercury and so on. The pollution caused by waste batteries is slow and far-reaching. When they are mixed with ordinary household garbage, under certain conditions, a series of chemical reactions will slowly occur, releasing toxic substances, which will pollute the atmosphere when burning and pollute groundwater or rivers and lakes when infiltrating underground; Once it enters the soil water source, it will enter the human body through the food chain, damaging people's nervous system, hematopoietic function, kidneys and bones. Therefore, it belongs to hazardous waste. Tests show that the amount of water polluted by mercury batteries exceeds the sum of a person's lifetime water consumption.

In the past, the river was crystal clear and small fish could be seen. Now the factory regards this river as a good place to discharge sewage in order to improve efficiency. The river was polluted by sewage, and passers-by quickly left.

Saving water means protecting our environment, that is, saving resources. We should take our own practical actions to protect the environment. The simplest way is to start from ourselves and pay attention to saving water. For example, turn off the faucet at any time after use; Water the flowers with vegetable washing water, rinse the mop and flush the toilet. Don't think that a few drops of water in the tap are nothing. A drop of water from the tap every second loses 36 cubic meters of water a year. If a household saves one side of water every month, how much water does the whole country save in one month?

Fortunately, now people have realized that the earth is polluted, and everyone has taken action. I hope those who haven't acted will bend down and pick up the paper on the ground, so that our tomorrow will be more beautiful and tidy!
