How Does Global
Warming Impact on Plants and Animals
Many scientists agree that global warming is primarily caused by the
burning of fossil fuels and other human activity. It affects humans
directly by causing changes in weather patterns. But it also has a
significant impact on the plants and animals of the world.
If global warming is not dealt with, it could have devastating
effects on many plant and animal species. This is tragic in itself,
and these effects could also cause further problems for us humans.
They could potentially affect our food sources, result in larger
numbers of pests, and much more.
Plants
Any gardener knows that most plants can only grow in certain types
of climate. This is just as true for trees and forest plants as it
is for rose bushes and decorative shrubs. So major changes in
climate could cause indigenous plants to die out in their natural
locations.
Many of these plants will not become extinct, but instead will begin
growing in more favorable climates. This will disrupt the existing
ecosystem and cause the plants that are already there to either die
out or migrate northward as well. This will hit especially hard in
the frozen tundra regions. The plants there will have nowhere else
to go, so the tundra will simply shrink away.
Animals
The demise of plants from their natural habitats is a terrible thing
for the animals that feed on them. Species who once had plentiful
food may find the plants in their diets more and more scarce. They
will be forced to either move northward, find new food sources, or
die.
Animals who live in the coldest climates are hit especially hard by
rising average temperatures. Sea ice is reduced, thereby shrinking
the hunting grounds of predators such as polar bears. The snow dens
of animals such as seals are in danger of caving in due to the
unusual warmth, often killing the seals. This is bad for the animals
themselves as well as for the predators that feed on them.
Fish and underwater mammals are also hit hard by global warming.
Many types of fish, such as salmon, need cool water in which to
reproduce. An upward shift in temperature would force them to
migrate northward in order to survive.
Animals that live underwater but feed on plants near the coastline,
such as manatees, also face danger. Rising water levels could wipe
out their food sources, as the water might suddenly become too deep
for the plants they eat to grow in.
These are just some of the potential effects that global warming
could have on plants and animals. Other unforeseen problems could
show themselves as well, because it is impossible to predict every
possible global warming scenario. The best thing we can do is to
work to end global warming, before existing problems worsen and
these hypotheses become reality.
