Many animals have been included in the list of endangered species and this is because their number is significantly reduced. This makes the animals to be at risk of becoming extinct and the cause of this is a combination of both natural and man-made factors. These factors include destruction of habitat, poaching, introduction of exotic species, pollution, diseases, and overcrowding. These have led to reduction in numbers of some species. Human activities have contributed to threatening of animal species.
To begin with, people have been dumping toxic wastes in the places where animals live leading to their death. People have also been encroaching the land where animals live thereby displacing the animals. Another thing is that people have been introducing into a natural habitat exotic species that prey on the native species (Dyke, 2008). If the native species being preyed on has other predators, the increased competition will greatly reduce the number of the animals being preyed on.
In addition, people have been illegally hunting wildlife for economic gains leading to a significant reduction of some species especially those whose body parts fetch a lot of money. However, not all factors are a making of human beings. Natural factors have also led to endangerment of some animal species. To begin with, sometimes a disease affects a certain population leading to death of a large number of the population members. Following this, the number of the animals is reduced greatly and so if the animals have predators, they will become an endangered species.
Another natural factor is overcrowding where limited resources are supposed to support different types of species leading to survival of the fittest and this means that some animals risk being wiped out (Dyke, 2008). It is clear that the cause of animal endangerment is a combination of various factors. Some of these factors are within human control but others are beyond human control. Reference Dyke, F. V.
