The threats towards coral reefs are growing everyday.
Even though there has been a drop of about 12 million tons in how many fish are
caught, the fisheries are
still catching fish they don't need. These fish end up dying. Lots of things
need coral reefs to keep them alive. Some of these are: eels, octopi, fish,
starfish, sponges, sharks, and many other animals. Fish, starfish, and sponges
depend on coral reefs for all reasons, such as food, air, water,
and shelter, hiding from predators, etc. Eels, sharks, and octopi need coral reefs
as a place to snatch a couple of fish for dinner. Many other animals also
reefs for these reasons. If we keep killing the coral reefs, the ecosystem
will be greatly affected.
There are also other
threats to the environment as well as over-fishing. Human contact can also
severely harm the
coral reefs. Divers touching the reef, barely brushing against it, can
damage the beautiful place so many animals call home. Another way coral reefs
can be destructed by humans is by dropping anchor over a reef. If the anchor
hits the reef, it could damage the coral, possibly not growing back for hundreds
Another threat is
industrial pollution. When builders clear areas to build homes soil washes
down stream, and it can smoother coral reefs. When it is covered it
prohibits the making of food. Another is that they mine the coral reefs
limestone and sand for building materials.
There are natural
threats to the coral reefs as well. Severe
place during the
both 1982-83 and 1997-98. Bleaching also took place in regions that were not
affected by El Niņo. Changes in the temperature of the water can also
affect coral reefs.
