Causes of animal extinction

Good Essays
Animal extinction is happening nowadays due to the multiple factors of environmental degradation. The primary cause of environmental degradation is human disturbance. Extinctions caused by human are generally considered to be are recent phenomena. When humans convert wild areas for agriculture, forestry, urban development, or water projects including dams, hydropower, and irrigation, they reduce or eliminate its usefulness as a habitat for the other species that live there. The temperature of the environmental impact varies with the cause, the habitat, the plants and animals that inhabit it. Fragmentation of habitat carries long term environmental impacts, some of which can destroy entire ecosystem. Habitat loss poses the greatest threat to species. Some wildlife species require large land in order to meet all of their needs for food, habitat, and other resources. These animals are called area sensitive. When the environment is fragmented, the large patches of habitat no longer exist. It becomes more difficult for the wildlife to get the resources to survive. A more critical result of habitat fragmentation is land disturbance. On the other hand, natural disaster is also one of the courses of animal extinction. Mother Nature causes environmental problems too. Things like landslides, earthquakes, tsunamis, hurricanes, and wildfires can completely decimate local plant and animal communities to the point where they can no longer function. This can either come about through physical destruction via natural disasters or by the long-term degradation of resources by the introduction of an invasive alien species to a new habitat. The latter often occurs after hurricanes, when lizards and insects are washed across small stretches of water to foreign environments. Sometimes, the environment cannot keep up with the new species, and degradation can occur. Acid rain is also normally occurs when sulphur dioxide from coal plant emission combines with moisture
