What I already do:
- Go vegan
- Don't drive a car
- Use a thermostat at a reasonable temperature, and set it to shut off at night and when you're not home
- Don't use plastic bags
- Buy mostly local
- Grow some of your own food (I live in a city appartment btw, and work full time - still doable)
- Don't use air conditionning
- Reduce, reuse, repurpose, repair, recycle
- Work on your craft skills and buy less (also a source of income)
- Take the train instead of the plane
- Don't rely on fossil fuels for electricity
What I plan to do in the future:
- Have no more than 2 kids
- Heat and power my home with solar energy (solar cells are not the only solution, solar tubes that heat water can provide for all your heat needs for cheap - this is widely used in China already)
