In our quest for the perfect lifestyle we are forgetting the bigger picture. Don't destroy our fellow mammals, live with them. I believe I may have a way to usefully dispose of any dead otters. Basically take one flattened otter, baste with blue curacao, or other orange based cordial, and roast for 2 hours. To hear commentators flippantly advising road users to merely 'slow down' in such areas is an insult to wildlife.
Monkeys do also.
Yet even creatures such as otters are mammals also. They may not resemble us as much as apes but they are indeed mammals. Indeed they, like us, use tools. I may be stating the obvious but it seems I have to. In our quest for the perfect lifestyle we are forgetting the bigger picture.
