While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is affected by human activities. Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. Some animals, however, have adapted to suburban environments. This includes such animals wildlife conservation act pdf domesticated cats, dogs, mice, and gerbils.
The animals were believed to be bound for China, to be sold in wild meat restaurants. Malaysia is home to a vast array of amazing wildlife. However, illegal hunting and trade poses a threat to Malaysia’s natural diversity. Many Amazon species, including peccaries, agoutis, turtles, turtle eggs, anacondas, armadillos, etc.
Others in these informal markets, such as monkeys and parrots, are destined for the pet trade, often smuggled into the United States. Still other Amazon species are popular ingredients in traditional medicines sold in local markets. The medicinal value of animal parts is based largely on superstition. Many nations have established their tourism sector around their natural wildlife. Mudamalai Wildlife Sanctuary are situated around and in forests.
Destruction of wildlife does not always lead to an extinction of the species in question, however, the dramatic loss of entire species across Earth dominates any review of wildlife destruction as extinction is the level of damage to a wild population from which there is no return. Overkill happens whenever hunting occurs at rates greater than the reproductive capacity of the population is being exploited. The effects of this are often noticed much more dramatically in slow growing populations such as many larger species of fish. Many processes associated with human habitation of an area cause loss of this area and decrease the carrying capacity of the land for that species. In many cases these changes in land use cause a patchy break-up of the wild landscape. Agricultural land frequently displays this type of extremely fragmented, or relictual, habitat. Farms sprawl across the landscape with patches of uncleared woodland or forest dotted in-between occasional paddocks.
Examples of habitat destruction include grazing of bushland by farmed animals, changes to natural fire regimes, forest clearing for timber production and wetland draining for city expansion. Frequently species that are uncommon in their home range become out-of-control invasions in distant but similar climates. The reality is that the vast majority of species exposed to a new habitat do not reproduce successfully. Occasionally, however, some populations do take hold and after a period of acclimation can increase in numbers significantly, having destructive effects on many elements of the native environment of which they have become part. This final group is one of secondary effects.
