The Emerald Planet is a serious talking to about why plants must not be ignored. We agree with him that plants are gorgeously overlooked, because no life on earth would exist without them. It’s all either plants or something that eats them and this is basically explains plants place in earth’s history. As we know how the oxygen in the earth’s atmosphere came from plants, the role of plants and trees in the carbon cycle and, of course, we all understand that carbon has a role in controlling our climate nowadays.

Basically, the early earth had no oxygen in its atmosphere, and when the first life emerged, microbial single-cell stuff, oxygen was poisonous to it, because it interfered with important biochemical reactions, but what plants did, or bacteria in the ocean did, was evolve a way of harnessing the carbon in sunlight and liberating oxygen in the process. Over time what happened is that oxygen built up in the atmosphere and we can see this in the fossil record. There are geological strata called red beds, iron-rich deposits. They are red because the iron rusted on exposure to oxygen, so there is a point in earth history where we can see the oxygen appear because the iron in the soil rusted.
