What are ways plants help us live?

Answer 1

they create oxygen...... DUH! ANSWER

The Earth is a closed ecosystem, which means that nothing can leave it, and nothing comes in from outside. Plants are an extremely important part of this ecosystem. They take in the Carbon Dioxide that we give off, process it for their own uses, and then give off Oxygen. As animals breath in Oxygen and give off Carbon Dioxide, plants take in Carbon Dioxide and give off Oxygen. Without sufficient plant life to keep up this trade, all animals on Earth (including us) would die.

The root systems of plants keep the topsoil in place. Topsoil is the only part of the Earth that can support farming, so, without plants to keep the topsoil in place, no other plants can grow. Plants also fertilize the soil when they die, as they decompose and add their nutrients to the soil. One of the main reasons for the Great Depression in the U.S. was that farmers had, unknowingly, plowed up the Grasses of the Midwest, and replaced them with crops that did not have sufficient root systems to keep the soil in place. The Dust Storms that followed when the rains failed made farming impossible in several States.

Also, plants contain valuable medicines for diseases. Nobody knows what cures are contained in the Amazon alone, because nobody has explored enough. Many of our current Wonder Drugs, however, are plant based. We know there are Many more cures in the forests.

This is a very incomplete list of the things plants do to help us. Maybe others can add to it.
