Yes its still legal in many places including Canada and Alaska.
I know the people against trapping play the heart strings of people to support them and their cause. But they simply don’t understand how nature works.
Please think about this; predators eat animals that’s what they do. Ok what happens if there are too many predators in a given area? Answer; they over use that food supply until they are forced to find another area or they starve to death. I could take you to areas here in Alaska where this has happened. You won’t see a deer or any small animals or ground birds such as grouse. You walk through the woods and its void of animals other than small birds passing through. And area like that can take decades to recover. Then there is a population boom because the predators are gone, no wolves, coyotes, no marten nothing. So the rabbits and other small game animals flourish. This draws in predators who then have a population explosion because of all the prey available and it all starts over again. This is the way of nature; death from a predator or starvation.
Now enter the trapper. He goes into an area and finds very few predators. He passes on that area because its not worth his time and money. So the predators there are let alone. He finds another area chuck full of predators and traps some. This helps the predators left there with less competition and helps the prey from being wiped out. It keeps a balance. And to be sure that balance is kept wildlife biologists keep tabs on population densities and recommend to Fish & Game or the D.N.R how many animals of what kind can be trapped there.
Bottom line if trapping was banned it will cause the starvation of predators and a huge loss of their prey. In some areas this means home owners will have starving predators come to their property and kill their pets and livestock.
I knew a woman who was against trapping wolves here in Alaska she fought hard to ban trapping. In just 2 years she moved out. The reason? Wolves killed her young horses and lamas, coyotes killed all her ducks and range chickens and her cats and small dogs. She lost everything she loved from hungry predators.
I hope this helps you understand how controlled trapping is beneficial to humans and nature.
