How can you help in the cleanliness of our land water and air?

You can plant trees. You can clean junk and liter out of a forest and on the road-anywhere. You can set up an appointment or mail a letter to the mayor or factory owner if you want to try to stop the industry from sending oil and polluting a lake or river or freshwater resource. You can also try to persuade people cutting down trees to repopulate them. When you knock down a tree, basically plant a seed to create another one in its place. That gives us more oxygen and will help us breath better.
