The first thing you have to do before you can make a decision about how to save the environment is to figure out what it is. Most people would say that the environment is our home, but if you think about it, the Earth is really just a big ball of water. The air we breathe, the land we walk on, and the water we drink are all part of the environment.
If you take into account all of these things, then you realize that there isn't much difference between our home and the environment. If you want to save the environment, then you have to learn how to care for your home, which includes taking care of the air and the water.
We need to keep the environment clean so that it doesn't harm us or anyone else. It's not easy to clean up pollution, but it's necessary if we want to protect ourselves from the things that harm the environment.
