>The Amazon produces a lot of oxygen, but so do soy farms and [cattle] pastures.

Could someone explain this quote from the article to me? I don't understand how a cattle pasture would produce as much oxygen as a rainforest.

I also don't understand the part about all the oxygen produced being used up due to respiration, surely that means that the world's forests would produce no oxygen for animals to breathe? That seems to completely oppose everything else I've ever seen about the oxygen trees produce.
