Many animals who make their homes in the forests will also disappear, and so will the animals who feed on these animals. This devastation will travel all the way up the food chain.
Trees produce most of our oxygen, also, so we would not have enough to breathe.
In addition, our source for lumber will disappear.
If the forests disappear, forest animals will disappear as well which can disrupt the whole food chain.
Oxygen levels will decrease and species of animals will gradually disappear.
That depends upon where they disappear to. If they are used in construction, the carbon contained in those forests will still remain sequestered. More likely, however, the forests will burn down, as our climate changes. This will release the carbon they contain into the atmosphere, accelerating the rate of global warming.
If forests disappear, it would lead to the loss of biodiversity, increase in greenhouse gas emissions, disruption of local and global ecosystems, and decline in essential ecosystem services such as oxygen production, carbon sequestration, and water regulation. This would have detrimental effects on the environment, wildlife, and human populations worldwide.
When did it happen?
We die
I guess nothing
We die
if the oxygen
Logging leads to deforestation, quite simply our forests disappear in time. If the forests are sparse or disappear all together in an area, then the animals in the area that lost their natural habitat will either die off or migrate to another area. Adaptation may occur in some cases, but is not likely.
The seals will disappear
We will all die!
