Are squirrels good for the environment, if so how?
Yes... because they are awesomely cute!!!! Really though, sort of similar to birds, they help with new growth of trees/plants when they gather nuts and seeds. Since they will often bury some, or drop them while they are scampering along. We have a couple of squirrel families in our yard, and I love watching them. Very cool little animals.
Yes, they plant their nuts and forget where they were planted resulting in trees growing from the nut
Don't know about that but they're really good with rice and biscuits.
