Humans impact Evergreen Coniferous Forests in a variety of ways.
====**Deforestation** is threatening large areas of evergreen coniferous forests. The forests are being cut down for lumber and to make room for farmland. As more trees are cut down the loss of habitat for animals such as bears, elk, and woodpeckers. This decreases the total available habitat and can hurt biodiversity. (I1) ====

==== **Global warming** - This is a mix in between the burning of fossil fuels and deforestation. The burning of fossil fuels adds more carbons dioxide than normal which is then worsened by the decrease of carbon absorbing trees. A tree can absorb 48 pounds of carbon dioxide every year. This increase of carbon dioxide in the atmosphere increments the Earth’s climate temperature. If this increase in climate keeps on going in 50 years boreal forest will be reduced 50%-90% because the climate conditions needed for coniferous forests will become rarer as temperatures increase. This also means an increase in deciduous trees.(I1) ====

====**Acid rain**,which contains higher than normal sulfuric and nitric acid, is caused by humans through the burning of fossil fuels in vehicles, power plants, and factories: it doesn’t necessarily kill the trees, but it weakens their leaves and also limits the amount of nutrients that is available to them. This hurts the amount of energy and nutrients available to an ecosystem and decreases biomass.(I4) ==== (I1)
