Here's a way to help conserve energy and reduce CO2 emissions that anyone can do, since it involves land use and agricultural practices.....
Grow your own vegetables
Might mean some of us will have to learn to become green thumbs, but it will most certainly cut back on having to use great swathes of land to raise vegetable crops, cutting back on CO2 emissions by leaving that land forested or grassland/wetlands etc. Also means less CO2 emissions from farming equipment used to harvest these crops etc.
Also means less power having to be supplied to large scale farming, thereby helping to reduce some power consumption (probably not much in the overall scheme of things, but some is better than none
)
