habitat loss and degradation
|
Detailed explanation-1: -Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples.
Detailed explanation-2: -Habitat loss is a consequence of human activities such as agriculture, urbanization, deforestation, resource extraction, alteration of the sea-floor due to trawling (fishing), or the release of pollutants.
Detailed explanation-3: -Habitats are degraded when their condition declines due to factors such as pollution, invasive species, and over-utilization of natural resources. Examples include prairies being invaded by woody species such as eastern red cedar and streams being degraded by runoff of sediments and chemicals from adjacent cropland.
