because theres oxygen, coming from trees :)
they breath out oxygen for the humans and breath in carbon dioxide which helps the earth have less carbon dioxide
Yes we can breath on earth, that's why we are living!
Yes Earth
i am not sure..........although i like earth
hydrosphere
because it has lots of air to breath
Because there is an ozone layer
Atmosphere.
Well plants and trees because they are the opposite to us they breath in CD and breath out oxygen!
protect the earth and havee oxygen to human breath
because people need oxygen to breath, in space there is no oxygen making people ineligible to breath.
If there were no plants on Earth, there would be no alternative life. This is because of Photosynthesis; the plants breath in the Carbon Dioxide and breath out Oxygen; which we need to live, and would die without.
