Essay

There is a discussion whether the killing of animals can be justified

or not. Many people think that all animals should be protected,

particularly native animals. However, some people feel that the killing of

animals should be allowed when they are over population, when animals

present a danger to humans, and when it is economically beneficial.

The culling of animals can be justified when the population of

certain animals is too large. Dr Graeme Colon, a kangaroo ecologist in

a lecture in the University of Melbourne said that it is a general rule, 100

kangaroos per square kilometers was a sign of trouble, because over

population lead to a widespread land degradation and widespread plant

loss, country will get overgrazed, because of the lack of food caused by

the drought in the area, but now it is 200 kangaroos per square

kilometers. They also compete with other grazing animals, the problem

like this situation will affect the balance of natural environment. So

animals should be culled when they are over population is to large and

have a treat to the natural environment and compete with other animals.

It is reasonable to kill animals when they present a danger to

humans. When some animals attack humans, they should be killed, such

as the grey nurse shark attacked at the spearfisherman and was going to

eat him, so he shot this shark and just in self-defense. ( Williams 2004 ).

People are in self-defense when some animals arrack them. In addition,

sometimes some animals spread disease to people as they should be

culled. For example, the serious eruption: in Hong Kong and in Vietnam.

Health officials thought the culling of birds to reduce the danger to

humans. ( Von Cluck 2005 ). Some people recognize that some animals

need to be culled, because they spread disease quickly to humans. So the

killing of animals can be justified when they present a danger to humans....
