pIs hunting a good way to manage animal populations?

I watched hunting decline in NJ over the years, it is so densely populated that the deer have taken up residence in every neighborhood. The deer have actually gotten smaller, I remember when a 130lb buck or a 110lb doe were normal as a kid hunting in the late 60's, now from what friends tell me there are very few over 100lbs or either sex. Bears, the state is overrun with them, my sister has to wait till the garbage truck is literally next door to take her garbage out and when the state decides to have a hunt to thin them out they have consider the court costs from the 'don't kill the bears crowd' that don't live in the country.
