An organic and sustainable lifestyle
Plant a garden. Use raised beds if room is limited
Grow or buy locally raised vegetables and preserve for winter use.
Bake your own bread
Plant fruit bushes vines and trees. Small fruits such as blueberries and grapes can easily fit into a suburban lot. Check with your local nursery and farmers market for dwarf and patio tree varieties.
Buy from local craftsmen for gift for others and yourself. Instead of driving to the mall, check out local shops which carry handmade gifts. Not only will they be unique, you are contributing to the local economy instead of China's.
