Further research has shown that many animals and birds carry this parasite, and the major source of water contamination is by humans. [ 10 ] [ 11 ] [ 12 ] Recent concerns point to domestic animals as a significant vector of giardia, with young calves in dairy herds testing as high as 100% positive for giardia. [ 13 ]
Trampling can increase erosion and decrease the filtration capacity of the soil, especially where animals create tracks, and fences can encourage the creation of tracks and wallows, creating a conduit for pollution that can overwhelm the effects of riparian restoration. [17]
Air pollution often exacerbates respiratory disease by permeating into the lung tissue and damaging the lungs. [70] Despite the wealth of environmental consequences listed above, local US governments tend to support the harmful practices of the animal production industry due to its strong economic benefits.
Due to the fittest animals in the species being hunted or poached, the less fit organisms will mate, causing less fitness in the generations to come. In addition to species fitness being lowered and therefore endangering species, the illegal wildlife trade has ecological costs.
Sand dune stabilization is a coastal management practice designed to prevent erosion of sand dunes. Sand dunes are common features of shoreline and desert environments. Dunes provide habitat for highly specialized plants and animals, including rare and endangered species. They can protect beaches from erosion and recruit sand to eroded beaches.
The meeting was prompted due to concern over tropical deforestation, disappearing species, and eroding genetic diversity within species. [8] The conference and proceedings that resulted [ 2 ] sought to initiate the bridging of a gap between theory in ecology and evolutionary genetics on the one hand and conservation policy and practice on the ...
Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
Biodiversity is also an essential part of global food security. There is evidence to support a trend of accelerating erosion of the genetic resources of agricultural plants and animals. [15] An increase in genetic similarity of agricultural plants and animals means an increased risk of food loss from major epidemics.
