Answer 1

An environmentalist obviously puts the wellbeing of the environment first, as a rule.  As far as knowledge, they would know about climate change, weather patterns, the effects of chemicals on the ecosystem, etc.  You would be concerned about reducing the human impact on the environment, and ensuring the survival of all the earths natural plant and animal species, among other things.
