It would cut off oxygen.
there actually be little to no trees and possibly we would all die
fewer mammals and birds can survive after trees have been cut down because it is their habitat and their food. cutting trees down will cause loss of habitat, and if there are too many animals of one species in the area, then some will die, especially the weaker ones. another problem with cutting trees down is that it no longer provides the oxygen that we need to survive. if we were to cut all the trees down, it would not be long until planet earth reflects what it is like to be in space, and everyone would die.
it would flood
Because it is powerful
It would be barren, and a lot of animal species would go extinct.
we get rain that if comes one time could drown the hole planet in fact if we cut down trees there will be no rain at all we will actually have a drought . with no water at all that is why we should stop cutting down trees
We will all die and the trees will come back and haunt our graves!! Prepare...
They wouldn't have a shelter, and die.
the carbon dioxide will increase
a) The trees ie. rainforest contains the widest diversity of organisms on the planet, get rid of the rainforest, and most of them will go extinct. b)The trees are a massive carbon sink (The trees 'lock' carbon inside their tissues, as well as converting it to Oxygen), chopping them down would hugely increase the levels of carbon dioxide in the environment
Some people beleive we would as trees give out alot of oxygen, but in actual fact, no, the human race would continue if all the trees where chopped down. I hope this helps and you get this answer as the answer before was wrong!
As long as it takes you to kill all the trees. It can be done by cutting them down or by girdling all of the trees. A single year would be more than adequate.
