*Habitat loss: Fewer natural wildlife habitat areas remain each year. Moreover, the habitat that remains has often been degraded to bear little resemblance to the wild areas which existed in the past. *Climate change: Because many types of plants and animals have specific habitat requirements, climate change could cause disastrous loss of wildlife species. A slight drop or rise in average rainfall will translate into large seasonal changes.Hibernating mammals, reptiles, amphibians and insects are harmed and disturbed. Plants and wildlife are sensitive to moisture change so, they will be harmed by any change in moisture level. *Pesticides and toxic chemical: Widely used, making the environment toxic to certain plants, insects, and rodents. Unregulated Hunting and poaching: Unregulated hunting and poaching causes a major threat to wildlife. Along with this, mismanagement of forest department and forest guards triggers this problem. *Natural phenomena: Floods, earthquakes, volcanoes, lightning, forest fires. *Pollution: Pollutants released into the environment are ingested by a wide variety of organisms. *Over-exploitation of resources: Exploitation of wild populations for food has resulted in population crashes (over-fishing and over-grazing for example) Perhaps the largest threat is the extreme growing indifference of the public to wildlife, conservation and environmental issues in general.
