As an individual, we can only make token efforts, or "feelgood" efforts. If enough people on the PLANET did their token bit it would be a small achievement. One of the best things an individual can do is to lobby their local government ministers to reduce carbon output and encourage businessess to use more green ways of working. Plant trees so birds, insects and other fauna can survive the rampant takeover of humans into the natural habitat, ergo forcing the fauna to move or perish. Sigh. It seems like an overwhelming task.
