Many types
of life forms from around the world are threatened because of
over-exploitation. This is when our use of that species or resource renders it
near extinction. Overpopulation has increased the “need” for over- exploitation,
a “need” that cannot be sustained at our current rate of consumption.
Over-harvesting
is a big problem with many of our natural resources. The harvesting of forests
and the extraction of oil and gas are examples of non renewable resources whose
over-use has severely impacted local environments and biodiversity.
Over-exploitation
is also a huge problem for wildlife. Fish are a very good example of this as every
year over 80 million fish are caught for human utilization. Sometimes the way
that the fishing is done destroys marine habitats and catches many other marine
animals by accident. These practices cause marine populations to shrink and
have a huge impact on biodiversity.
Species
trade is a very big problem in many countries. Thousands of plants and animals
are taken from their natural habitats every day to be sold, traded or made into
various products, including gifts (ivory from elephant tusks, coral, sea turtle
shells and reptile skins are popular souvenirs that threaten species). Other
products, like traditional Chinese medicines, can also be made using threatened
and endangered animals.
Animals
are often traded as well. But it’s not just the large animals that are trapped
and traded. Insects like butterflies and rare coral fish are also illegally
traded.
Over-exploitation seems to be swept under the
rug as we continue to perpetuate the over consumptive attitude that fuels the
over-exploitation of our natural resources. We as a people have to change our
attitude one person at a time to help further the concept of biodiversity
