However hopeless preventing and ameliorating the effects of climate change seems to be sometimes, and however depressed we become, it is something we must work on. The consequences of doing nothing are so grave - so dismal - and affect not only our children and grandchildren but every ecosystem in the world that we must continue. Did the Polish cavalry charge Nazi tanks? Yes they did ..... Did the British surrender at the threat of the German invasion? No they did not.....Did Estonians forget their language living under Soviet rule? No, they did not.... They all did the right thing.
So we too must do the right thing ..... however close disaster seems. And millions of people are working on saving the planet - check out http://www.350.org/ or http://www.wiserearth.org/ if you feel you are alone. Excelsior!
(By the way, I highly recommend watching Adventures of Priscilla, Queen of the Desert as a cure for depression.)
