Question

During daylight hours, plants and algae take in carbon dioxide and release oxygen. If humans remove forests, what might happen to the balance between these gases? (2 points)

Answer 1

There might not be enough oxygen for us to survive. As the plants and animals circulate the flow of oxygen and carbon, it wouldn’t be enough. Say you were trapped in a vacuum (not the one you use to clean your house). You would have only enough oxygen in your lungs to last you for a little while, but then there is too much carbon in the air that we exhale. Plants and animals use that carbon to release oxygen. So, without them, earth would be filled with carbon
