Discuss the main threats to the ecosystem?

Answer 1

There are generally considered to be nine major threats to the stability of ecosystems on Earth. Climate change and loss of biodiversity are often the most publicised, although there are seven other factors that may be equally threatening.

The spread of agriculture and other human activities into natural habitats poses a large threat to ecosystems. Similarly, the disruption of fresh water systems through damming and diversion by humans can lead to vast habitats becoming dry and barren.

Chemical pollution can have devastating effects of the health of ecosystems (as well as humans) and the release of aerosols into the atmosphere (through activities such as burning fossil fuels) damages ecosystems in numerous ways. The release of aerosols (among other things) can also lead to the depletion of the ozone layer which threatens to allow harmful solar radiation to cause damage to organisms and ecosystems.

A potential threat to global ecosystems that is rarely discussed is the acidification of the oceans due to increased carbon dioxide in the atmosphere, which can have serious knock-on effects on important aspects of ocean chemistry. Lastly, the disruption of the nitrogen cycle can lead to bacteria converting too much nitrogen from the atmosphere into a form not readily available for living things (this is often encouraged by agriculture to give higher crop yields).

Of course, many of these threats are interlinked and if one threat were to go unchecked and get out of control, others will likely follow suit.

In 2009, the current threat level from each of these factors was assessed. Climate change, disruption of the nitrogen cycle and the rate of biodiversity loss were considered to pose the most imminent threats to ecosystems on Earth, although others were not far behind.

Answer 2

extinction because after one of the things are extincted then the animals that eats it has nothing to eat so they will have to move away and if the next ecosystem is too far then they have nowhere to live so they die

Answer 3

-Deforestation

-Drought

-Fire

-Storms

Answer 4

One of the main threats to the ecosystem is the presence of humans. Human intervention in areas can have a devastating impact on the ecosystem.
