Human Impacts on Ecosystem

Question 1

H.I.P.P.O.

Answer 1

H=Habitat Loss, I=Invasive Species, P=Pollution, P=Human Population, and O=Overharvesting.

Question 2

Examples of Habitat Loss

Answer 2

Habitat loss is a consequence of human activities such as agriculture, urbanization, deforestation, resource extraction.

As cities grow vital habitat is destroyed or fragmented into patches not big enough to support complex ecological communities. In the city, species may become endangered, or even locally extinct as previously natural areas are swallowed up by the urban jungle

Question 3

Examples of Invasive Species

Answer 3

The increase of activities such as tourism and trade have meant people and goods can move all over the planet, and they often take invasive species with them, accidentally or intentionally. Predation of native species.

Question 4

Examples of Population Explosion

Answer 4

Increased climate change due to increase in fossil fuel emissions and waste pollution. Increased use of resources and more waste.

Question 5

Overharvesting

Answer 5

Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.

Poaching, causing disruption of food chains.
