Where do we get the oxygen that we breathe from?

yes yes in a sertain way it does the sun can keep you alive and healthy for about half an hour a day but a little more than that can burn your skin and some people get skin cancer so the sun is good and bad. for another example we're like plants give it some sun and it will stay healthy and green give it too much sun and it will dry out and die. i hope that answeres your question.
