Although large populations of urban wildlife such as squirrels and sparrows can cause health and safety concerns, they fulfill vital rolls in local ecosystems. For instance, squirrels and sparrows help spread seeds and pollinate plants which helps increase bird, butterfly and bee populations. Both also serve as food for other urban wildlife such as hawks, owls and other raptors. Their manure also improves compost, although clearly precautions such as using respirators are necessary, as is misting rabies vaccine.
Yes, someone has the right to get rid of pests like squirrels and sparrows if these pests are on their private property. Property owners want to live without being bothered by pests, as well as protect the value of their property. This gives owners the right to exterminate unwanted pests; controlling their populations.
Yes. Why would anybody disagree with controlling the pest population? I would think this would be a question everyone could agree upon. I guess it depends on the way to get rid of them, but I wouldn't want my neighborhood run over with vermin. It find to control the pest population.
Squirrels, birds, and other pests are not good for certain environments and need to be controlled. Especially in the city, these animals can wreak havoc on homes, gardens and yards, causing people grief. Limiting their population would help to reduce these problems, and should be seriously considered. Nobody is going to miss a few pests.
