Habitat Loss Habitat loss—due to destruction‚ fragmentation or degradation of habitat—is the primary threat to the survival of wildlife in the United States. When an ecosystem has been dramatically changed by human activities—such as agriculture‚ oil and gas exploration‚ commercial development or water diversion—it may no longer be able to provide the food‚ water‚ cover‚ and places to raise young. Every day there are fewer places left that wildlife can call home. There are three major kinds

May 1995). And today‚ five of five can be attributed to human beings. These factors can begin as snowflakes‚ transform into

Essential Fish Habitat (EFH) are bodies of water and substrate required for fish spawning‚ breeding‚ feeding‚ and a place they can grow to maturity. Bodies of water (freshwater‚ estuaries and saltwater systems) that fishes use as habitat have physical‚ chemical‚ and biological components and also include historical aquatic environments that fish have always used.[1] Important essential fish habitat characteristics include sediment type‚ type of bottoms (sand‚ silly and clay)‚ structures underlying

how are humans accelerating species extinction? The main causes of extinction due to humans are HIPPCO: Habitat destruction‚ degradation‚ and fragmentation; Invasive species; Population growth and increasing use of resources; Pollution; Climate change; and Overexploitation. The biggest threat to wild species is habitat loss‚ degradation‚ and fragmentation. A perfect example of this is the loss of habitat for the polar bears. Because of global warming‚ there have been less floating ice sheets in

The greatest concern among environmentalist in the last decade or so is the rising destructive behavior of man throughout the world.We are a nation that are slowly suffocating ourselves with dangerously destructive nature.The Earth itself has retaliated with several warning signals in the last few months.The recent earthquake in Haiti which has resulted in the death of 150 000 people and more is one such example.It is one of several major natural disasters in the last few years that have wiped out

of the country’s biodiversity is found outside protected areas. Steep decline in wildlife populations has occurred in rangelands outside protected areas due to rapid changes in land use leading to wildlife habitat loss through essentially land fragmentation for intensive settlement and cultivation of agricultural crops‚ which in turn fuel human wildlife conflicts. Poaching for commercial trade and for bush – meat are major cause for decline in wildlife populations and challenge for wildlife conservation

Land Pollution Land pollution is pollution of the Earth’s natural land surface by industrial‚ commercial‚ domestic and agricultural activities. Causes of Land Pollution 1. Degenerative Actions Degenerative Actions encompass a lot of human actions‚ including - deforestation‚ overuse of pesticides and chemical fertilizers‚ desertification‚ mining‚ inefficient and / or inadequate waste treatment‚ landfill‚ litter‚ etc. 2. Misuse of Land Misuse of Land mainly refers to felling of trees to

Anthropogenic habitat fragmentation has affected‚ and will continue to affect the dynamics of populations for most organism types that are subjected to it. From the physical structures we construct for the conveniences of humankind to the deterioration of continuity in our forests and other vast ecosystems that we have exploited to support urbanization and development of land‚ we are changing the ways in which organisms can use the landscapes to which they have evolved. By creating barriers and inhospitable
