We should protect water resources. Although we all know that water is a very important resource in life, there are still cases of river water being polluted around us. So what we can do is not to throw domestic garbage into the river, and those factories should also strengthen management and not to discharge chemical raw materials into the river.
Man needs water, and so does the earth, but water is limited, so we should save water. In life, we can turn off the tap in time, flush the vegetable washing water into the toilet, water the flowers with rice and reduce the number of baths. In a word, we should use water rationally and don't waste water, because wasting water is wasting life.
We should save electricity, because with the increase of electricity consumption, the earth will be very hard. Turn off the lights, watch less TV and play less computer, and avoid turning on some electrical appliances for a long time, which can effectively save electricity. Sometimes we can use solar energy to convert it into electricity, which is also very environmentally friendly.
