It is very important to leave the wildlife alone as long as there are no injury. Many Whites can only take care of some animal(s) who were hurt and then let the animal(s) back into the Wild. And often they don't. But still the Whites kept on taking care of the animals for longer period. So are the baby animals who are not able to fend themselves into the Wild if there is education to teach the baby animals how to survive in the Wild.
As for the couple in the snowmobiles carry their guns for protection from the Wild like Wolves, Bears and probably Moose but they were getting too close to the Moose. The Moose is a big animal and could charge them head on to them but if not, then the couple should not be there in the first place. The Moose do not like to be harass by people like this couple. Well, too bad that the YouTube gave away what they were doing in the Woods.
