Do you know the saying, "Plant a Tree Today For All The World To Share?" Well, I bet you are wondering how, exactly, that works. Trees are a type of renewable resource, they take in Co2, or Carbon Dioxide and they take out oxygen, which is what us, people and lots of animals too, need to survive. They help reduce the amount of CO2 in our environment, and the world.
But that's not all it's good for, trees can also be used for biofuel, and biofuel is also a renewable resource. Instead of using oil, and gas, and other resources that pollute the earth, you could use biofuel. And biofuel is made out of stuff like trees. So overall, trees are really good for us and the environment.
There is a negative about trees, though. When you cut the trees down for wood, and when you burn the wood, it can pollute the Earth, and it could stay that way if you are not careful. Industries that do that plant another tree to replace the one which was chopped down.
If you care about the future of our planet, you should lend a hand a plant a tree today, because you really are sharing the wonders of it with the world.
