An environmentalist is a person who has adopted environmentalism as a philosophy that makes this person work and manages to direct their activities towards the preservation of the environment and sustainable development. These people seek to teach others to preserve the environment and seek to defend it through politics, economics and any other social factor that can help to achieve this goal.

The answer should be by sweating.
When the temperature increases in the body, it's unlikely for the body to shiver. The body cools off with water that excretes from sweat glands so that you won't get overheated. Goosebumps (for temperature purposes) are only formed when the body is cold; the same goes for the hand strands standing up.
