What three human activies are threatening both coral reefs and coastal ecosystems?

Answer 1

Hunting

• Overhunting is a problem throughout the world despite many government attempts to keep poaching and overharvesting at bay. The killing of animals for food can be beneficial to an extent because of the disease and other problems related to overpopulation of a species. But when a species is hunted to extremes, its numbers eventually begin to decline and it becomes endangered or extinct. Since animals all play some role in the ecosystem, this type of hunting threatens the balance in nature that exists.

Deforestation

• The ecosystem is constantly threatened because of habitat destruction. One of the most disturbing human activities concerning the environment is the mass deforestation for agricultural purposes or land development.
• All species of animals have specific needs in their habitat, and some rely on a relatively small habitat that may not exist elsewhere. Once humans level the forest they call home, they are likely to disappear form existence over time.

Non-Native Species Introductions

• The ecosystem is a delicate balance of plant and animal species that belong in a particular area. But humans introduce non-native species to new habitats for their own purposes. For example, an animal is introduced to a new area where it did not previously exist to help cut down on a rodent overpopulation. Eventually the new animal begins to have its own impact on the new area, and often it results in trouble for other native species. Non-native plants may also become a problem by taking over existing native species in a new place, meaning an important flower or herb may be smothered out.

Answer 2

deforestation (the act of cutting down trees) , pollution (air & water) and carbon emissions - factories, transportation - release this into the atmosphere. In addition, all of these are factors are main contributors towards Global Warming.

Answer 3

High intensity Logging operations in heavily forested areas, like the South American rainforest, Draining of swamps and bogs, which can have bad effects on native wildflowers and amphibians, and use of agricultural pesticides, which can get into the water cycle and poison non-target species.

Answer 4

using a machine, but we destroy the ecosystem because of noise pollution is the big destruction of the ecosystem, because we interrupt the communication of other animals and insects. jamokz
