Primarily, they play a pivotal role in the proper functioning of the ecosystem. There are countless 
examples of how a decrease or increase in a particular animal species affects humankind. For 
example, bees help in transferring pollen grains. If bees are reduced in number, there would be 
low crop yields due to the dearth of pollination. Another classic example would be of tigers, 
which are dangerously decreasing in number. Due to the decrease in tigers, the deer population 
may increase. Deers feed on grass. Increased grazing will lead to loss of habitat for many other 
species. Also, the deers may venture out from forests to cities and towns for food. Thus it is 
imperative to conserve wildlife.  
 
Some species are unique to a particular place. For example, kangaroos are famous in Australia. 
Kangaroos bring in a lot of revenue in the form of visitors. Some species help in maintaining the 
health of the soil, which is of great help to farmers. For example, the earthworm feeds on plant 
and animal wastes, decomposes them, and releases chemicals that restore the soil's nutrients. 
 
Man has caused so many problems to wildlife in the form of hunting, poaching, and 
deforestation. Man derives innumerous benefits from animals. So the amount spent on them is 
comparatively less. So people who claim that we are spending too much money on wildlife 
conservation have to sink their differences and help build a good ecosystem. 
 
In conclusion, money spent on conservation of wildlife is vindicated. Any step taken towards 
this cause should be appreciated.
