Climate change has already affected migration patterns, and infected birds may move to deforested areas that are more suitable habitats for them, spreading their diseases to the local bird populations. They write new content and verify and edit content received from contributors. The main cause of man-made erosion is agriculture, followed by construction and mining.

The problem is were just not getting enough water, Davis said. With the loss of trees and entire forests, homelands are also being destroyed in the process. All told, deforestation causes a triple-whammy of global warming: We lose a crucial ally in keeping excess carbon out of the atmosphere (and in slowing global warming), Even more emissions are created when felled trees release the carbon theyd been storing, and rot or burn on the forest floor, and Water is very effective at doing work. While some of them move into areas occupied by other tribes, straining the lands resources, others are forced to relocate to urban settings and completely change their way of living. However, if crops are introduced on a smaller scale and don't displace native species, they can actually increase diversity since they can act as a habitat for birds and herbivores. Higher food prices, water availability, violent conflicts for land, migration, increasing poverty, pollution from wind-blown dust particles coming from distant lands, could be the outcomes of desertification if we let it consume more of our planet. Water temperatures increase because the trees that provide cover from sunlight are cut down. The extent to which forests have become Earths grazing lands is much more difficult to assess. We dont get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water.
