question 7 (essay worth 5 points)
increasing carbon dioxide from fossil fuel combustion is an anthropogenic activity that is causing an ecological consequence by excessively emitting carbon dioxide into the atmosphere. aside from this example, think of and describe an instance how another anthropogenic activity is causing ecological consequences. be sure to explain which ecosystem service or services are affected by this activity.

Explanation:

Fossil - fuel combustion emits excessive CO2, causing global warming which affects ecosystem services like pollination and water purification. Another example is deforestation. Trees absorb CO2, and when cut down, less CO2 is sequestered, and habitats are destroyed, disrupting food - webs and reducing biodiversity.

Answer:

An example of an anthropogenic activity causing ecological consequences is deforestation. Trees play a crucial role in carbon sequestration. When forests are cleared for activities like agriculture or urbanization, the amount of carbon dioxide that can be absorbed by trees is reduced. This leads to an increase in atmospheric CO2 levels. Additionally, deforestation destroys habitats for countless species, leading to a loss of biodiversity. Ecosystem services such as soil stabilization, water purification, and pollination are also affected. For instance, without tree roots to hold the soil in place, soil erosion can occur, which can impact water quality and agricultural productivity.
