Worrying is obsession thinking which goes nowhere.
Add an action plan on 4 levels:
1. personal - these are thing you can do right away that may take away some of the worry, but not all.
2. align with groups like Move-On, NRDC, Greenpeace to petition government to stop the use of fossil fuels on all levels ASAP.
3. For those you are physically able and have the time (out of work, students, between jobs) Protest in the Streets, join Strikes. For those that are disabled and/or elders support the strikers by donating to protestors, strikers etc., writing campaigns. MASSIVE CIVIL DISOBEDIENCE.
4. Join local groups that protest and promote sustainable energy resources.
