The Carbon Cycle
Science-Carbon Cycle
When animals or humans breathe out they release carbon, and that is how plants get it, so that they can turn it into food and release oxygen so that the whole process will start all over again.
Burning oil can harm the atmosphere. How? It adds a lot of carbon to the air.
Burning coal can harm it as well, if there is too much carbon that can hurt the atmosphere causing global warming, and the greenhouse effect.
But if we don't burn as much coal or oil anymore, then we can reduce the greenhouse gas emission and global warming. Humans are partially hurting the atmosphere, and too put a stop to that we need to stand together and stop harming it.
