Many scientists try to separate advocacy and science, but that’s probably not a good idea:

The only two logically sound arguments that emerge, say the researchers, are the social harm that might result if scientists, who are the true experts, don’t advocate; and the fact that researchers are citizens first and scientists second, and therefore have an obligation to advocate.

Speaking of advocacy, climate change is almost certainly going to make most of Europe too warm for butterflies.  Things you should do to help deal with climate change: have fewer or no children, use less, and encourage your lawmakers to fund research and protect the environment.
