When I can afford it in the next few years, I plan on doing solar on the house. I drive as infrequently as possible and prefer my motorbike over my car (though my car is also only 660cc engine). I grow some of my own food and plan to steadily increase that as I learn and get better at farming. I try to buy local and regional where possible. I've stopped buying beef at home and it is now a special occasion food a handful of times a year.

I'm just one dude and ultimately make little difference, but I do care.
