If you feel strongly that the UK will not benefit from leaving the EU, then why not join a pro-Remain group?
Find like-minded individuals with ideas and suggestions on how to make a difference.
Here is a list for starters:
InFacts is a journalist-based group dedicated to making the best of post-referendum Britain. The group fights against a destructive Brexit with up-to-date news and comment, articles, a great MythBusters section, and animation too.
Scientists for EU is a campaign group dedicated to keeping the UK in the EU. Science is increasingly international, so it is madness to isolate our scientific community?
