Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Human activity is by far the biggest cause of habitat loss. The loss of wetlands, plains, lakes, and other natural environments all destroy or degrade habitat, as do other human activities such as introducing invasive species, polluting, trading in wildlife, and engaging in wars.

The main effects for the presence of strong human wildlife conflict in the study area include crop damage, livestock depredation, killing of wildlife and habitat disturbance.

Habitat destruction by human activity is mainly for the purpose of harvesting natural resources for industry production and urbanization. Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling and urban sprawl.

Habitat loss, climate change, and a lack of biodiversity can all make ecosystems unhealthy, putting wildlife at greater risk for disease. Every day the byproducts of our daily lives make their way via the air and water into the natural environment and become pollutants.

Q2. How have human activities affected the depletion of flora and fauna? Explain. Answer: Cutting down of forests for agricultural expansion, large scale developmental projects, grazing and fuel wood collection and for urbanization has led to the depletion of flora and fauna.

Human-wildlife conflict (HWC) occurs when animals pose a direct and recurring threat to the livelihood or safety of people, leading to the persecution of that species. Retaliation against the species blamed often ensues, leading to conflict about what should be done to remedy the situation.

Avoid feeding wild animals, securely store your garbage, and feed pets indoors to avoid attracting unwanted visitors. Fence in your garden, and plant unpalatable vegetation to discourage browsing. Be prepared – Before camping, hiking, or venturing into natural areas, learn about the animals that you might encounter.

The primary effect of habitat destruction is a reduction in biodiversity, which refers to the variety and abundance of different species of animals and plants in a particular setting. When an animal loses the natural home or habitat that it needs to survive, its numbers decline rapidly, and it moves toward extinction.

When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Most amphibian species are also threatened by native habitat loss, and some species are now only breeding in modified habitat.

Areas where animals once roamed freely are now inhabited by humans. There is little give and take when wildlife is considered. Habitat where animals once freely roamed keeps shrinking for housing. Wildlife can become desperate after encroachment reduces their food sources.

The researchers attributed the effects to habitat change and fragmentation via physical movement barriers, and food and water availability via human sources. This impact of ours is especially worrying because it’s one that cannot be reversed or eliminated.

Habitat degradation is the due to human disruption of the ecosystem which has resulted in wildlife habitats that can no longer support wildlife.While the U.S. Department of Agriculture statistics show the latest report of the forest land has been stable since 1907. Stability does not mean there is no change in forest land area.

Humans have negatively impacted animal wildlife and their habitats. What can we do to bring awareness and help change these devastating effects? Sadly it is estimated that over the next 50 years 30% of United States animal species are at risk of disappearing due to human actions and activities.
