The Number One Thing I Can Do To Save Planet Earth.

I have been looking for the best way to save the big blue ball we call Earth...well, for six decades anyhow. I don't seem to be able to convince others that this is the single 'most important' issue that humanity faces. I haven't really motivated a single person to change any of their behaviors while they live out their appointed session on this planet. My opinion and counsel about Earth rescue does not register with a single soul within shouting distance of me. I am not an "influencer". Doesn't matter how I vote or what I promote. The world continues to roll down this slippery slope toward catastrophic fever and eventual unlivability. So, what am I left with? What can be my greatest contribution to solving this Earths dilemma? Where can I make a difference that will pull humanity and it's ultimate Mother out of this daily tailspin? When I walk down the path from my house (which I built with my own two hands and a couple of good friends) two hundred feet to my garage, which harbours my two gas-powered motor vehicles. I check the temperature and road conditions, deciding to not fire-up either of these dragons, making the all important decision to pedal my acoustic/non-electric bicycle to work...it's all I've got. Seriously, it's the only important decision that I have to make which possibly leads to the world evolving into a more livable environment and to bring down Earth's fever.
