How did trees get on earth?
Trees are of course non-marine plants: they live on land and not in the sea. The first plants to invade the land did so about 430 million years ago in the silurian, before vertebrates invaded the land. … The first seedplants evolved trees with seeds which thus colonized the lands and formed the first vast forests.

How many trees were there 100 years ago?

How many trees are left?
The answer is that the world is home to over three trillion trees—with almost half of them living in tropical or subtropical forests. There are roughly 400 trees for every human. 12,000 years ago, before the advent of agriculture, Earth had twice as many trees as it does now.

How many trees does a human need?
A human breathes about 9.5 tonnes of air in a year, but oxygen only makes up about 23 per cent of that air, by mass, and we only extract a little over a third of the oxygen from each breath. That works out to a total of about 740kg of oxygen per year. Which is, very roughly, seven or eight trees’ worth.

Do trees feel pain?
Unlike us and other animals, plants do not have nociceptors, the specific types of receptors that are programmed to respond to pain. They also, of course, don’t have brains, so they lack the machinery necessary to turn those stimuli into an actual experience. This is why plants are incapable of feeling pain.
