It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion.
When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
Dobbingstone Burn, Scotland—This photo illustrates two different types of erosion affecting the same place. Valley erosion is occurring due to the flow of the stream, and the boulders and stones (and much of the soil) that are lying on the edges are glacial till that was left behind as ice age glaciers flowed over the terrain.
Following findings that the parasite Giardia lamblia, which causes giardiasis, was putatively carried by beavers, the term "beaver fever" was coined by the American press in the 1970s. Further research has shown that many animals and birds carry this parasite, and the major source of water contamination is by humans.
In the last three decades, erosion that follows wildfires has accelerated across California as climate change continues to intensify both fires and rainstorms, according to new research.
Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, [11] [12] [13] neoliberal economic policies [14] [15] [16] and rapid economic growth, [17] overconsumption, overexploitation, pollution, and deforestation.
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
