Question

State any four effects of natural intervention on the environment

Answer 1

Answer:

types of effects of natural intervention on environment

Explanation:

Climate Change

Human activities in the environment interfere with the planet's natural balance, making the Earth’s climate less stable and predictable. Climate change brings abnormal occurrences such as unprecedented flooding; increased numbers of storms, hurricanes and typhoons; fiercer brush fires; and most notably tsunamis, which are uncommon in the Earth’s recent history. Phenomena such as rising sea levels, unseasonably high temperatures and drought hint toward an environment that cannot take much more negative human impact.

Water Contamination

Human intervention in the environment also jeopardizes the supply and flow of clean drinking water. Activities like waste disposal from residential, commercial and industrial areas, oil spills and runoff from agriculture all contaminate bodies of water. The direct deposit of pollutants into lakes, rivers, seas and streams and indirect runoff of hazardous substances during the rainy seasons both impact water sources. Another environmental issue impacting water systems is overfishing, which causes a reduction in diversity of marine life.

Air Pollution

One of the biggest environmental impacts of human activities is air quality. The transportation sector contributes heavily to air pollution because most forms of transportation, including cars, planes and ocean vessels, use fossil fuels. When burned, fossil fuels release carbon dioxide and other greenhouse gases into the environment.

Land Degradation

There are many examples of human failure to use land resources sustainably. Deforestation occurs when humans clear forests to use the land either for agriculture or for habitation. Consequently, forest cover dwindles significantly, leading to soil erosion and extinction of plant species. Land animals also decline in numbers and even face extinction due to human expansion that encroaches on their natural habitat and limits their ability to spread geographically.
