If anything, it has to be favorable.

If cow flatulance (farts) are polluting the atmosphere, deer flatulance must also be suspect. Ditto with the entire animal kingdom.

We have seen big increases in the Canada Geese populations and a population explosion in the case of Snow Geese. Biologists are warning us that the snow geese are so overpopulated that they are destroying the habitat in the far North. Meaning, there are so many of them that they are overwhelming the food supply. In effort to control the population the daily bag limits and the possession limits for snow geese has been raise to levels that have not been seen in the last 50 years. To this point hunters have not been getting the job done as there are not as many hunters in the field. Nevertheless. controlling wildlife populations through hunting plays a significant role in protecting the environment. To a large extent we are seeing game species out of control because there is so much feed for them provided by our agricultural lands. That is to say, it is a manmade problem and one that requires are intervention. Once the farmers have harvested, these species are forced to depend on the natural habitat. Out of control populations foraging desperately can damage the environment and starve despite their best efforts.

Uncontrolled hunting can cause the elimination of species, as with the wolves and the plains bison, but controlled hunting keeps populations inside an area's capacity. If there was no hunting, the population would eat out all the food sources and eventually starve. Where I deer hunt in Sauk Co. Wisconsin, Earn-a-Buck has been going on for 25 years as well as multiple other special seasons to try and control the deer population, but the numbers just stay pretty even. The DNR even dropped a pack of 22 wolves off in Sauk Co. to help kill off the deer. The deer population stays high though because they have endless food due to the fact that most of the county is farm fields.
