*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.
