Environmental balance
Living beings breathe in oxygen and throw out carbon dioxide but the plants take in carbon dioxide and throw out oxygen so the air stays balanced.
What we can do to maintain our ecosystem-
-Plant more trees.
-We can stop killing animals.
-We can stop using plastic (example, Japan has made a spoon which after eating your meal you can also eat the spoon).
-We can try and reduce pollution by car pooling and using electric cars
-By saving electricity and water
