1. How to protect the environment?

A good environment can make people feel happy and healthy. Improving the environment means improving our lives. We should plant more trees and flowers around. We should not cut them down. We should stop factories from discharging waste water into rivers and waste gas into the air. Whenever we see rubbish on the ground, we should pick it up and throw it into the dustbin. Don't spit in public. Don't draw on the public wall. Protecting the environment is our duty.

2. Save the planet

As time goes on, man is making the earth sick. People cut down too many trees and litter everywhere. Factories discharge waste, but they don't treat it in An Ying. This has caused some serious problems. For example, the land is sandy, the rivers are dirty, the air is not very clean, and even the temperature of the earth is rising. What should we do to save the earth? My suggestion is that we should plant more trees, put the garbage in the dustbin, and prevent factories from discharging the garbage directly into the air or rivers. In a word, we only have one earth, and we should try our best to protect it, otherwise we will regret it.

3. Protect our city.

It is very important to deal with urban garbage. Garbage must be thrown away or reused properly. Otherwise, it may cause many problems. It can pollute air and water. When people breathe polluted air or drink polluted water, they may get sick.

Our city has begun to face this problem. Some rubbish is sorted and sent to a certain place. The waste gas was purified before it was discharged into the air. Waste water should also be purified before it is discharged into rivers.

People should be stopped from throwing rubbish everywhere. We should try our best to protect our environment and fight pollution.

4. On the topic of environmental protection

Our environment is very important to our life. We need fresh air, clean water and so on. In the past, there were many trees around us, with fresh air and clear rivers. But now, people cut down many trees. Air pollution and water pollution are very serious. The environment around us has become very bad. We should protect our environment. First of all, we should plant many trees to keep water. Secondly, we can go to school and work by bike or on foot. Third, we shouldn't throw dirty water into the river. Fourthly, we should not use plastic bags. Finally, we can invite more people to join us.

5. Environmental protection

Today, the quality of our natural environment has become an important issue. The world population is growing so fast that the world has become too crowded. We are exhausting our natural resources and polluting our environment with dangerous chemicals. If we continue to do this, life on earth will not survive.

People concerned have made some progress in environmental protection. Many governments have made laws to protect air, forests and marine resources and to stop environmental pollution.

More measures should be taken to solve environmental problems. We should further educate people to realize the importance of these problems, use modern contraceptive methods, protect our natural resources and recycle our products. We are sure that we will have a better and cleaner place in the future.

6. Water (water)

Water is very important to living things. Without water, there would be no life on the earth. All animals and plants need water. Humans also need water. We need water to drink, cook food and clean our bodies. Offices, factories, schools and hospitals all need water.

Seen from space, the earth looks like a huge sphere covered with water. Water covers about 70% of the earth's surface. There is water in oceans, rivers and lakes. Even in the driest place in the world, there is some water in the air. There is water almost everywhere.
