First, urban expansion and the demand for more agricultural land lead to the destruction of habitats that house thousands of animals. For example, farmers clear forests to make room for planting crops and raising livestock, not to mention other logging operations that provide timber and paper products. Without the trees which offer shelters and food sources, wild creatures will gradually die out. Second, man-made pollution also contributes to the loss of species. In particular, industrial plants dump sewage and other toxic substances into the water and kill off the fish; similarly, marine life in the ocean might be completely eradicated in the event of oil spills during the exploitation and transportation processes.]]> 2021-11-29 08:48:13 UTC https://padlet.com/kimchitran212/grade11_unit10/wish/1917406373 https://padlet.com/kimchitran212/grade11_unit10/wish/1917408005 There are two main explanations for the disappearance of species.

Other persistent threats to animal populations include disease. For example, when European farmers began to use the horsepox virus against cattle in the late 18th century, their herds were decimated and horsepox soon became one of North America's most widespread diseases.]]> 2021-11-29 08:49:34 UTC https://padlet.com/kimchitran212/grade11_unit10/wish/1917408502
