My first exposure to things that weren't all industrial was my father and his home garden. Back then, I thought it was so old-fashioned, but today I am amazed at what he did. I'm the one who has replaced incandescent bulbs with flourescent bulbs, use the recycling at the condo, buy used instead of new, and buy organic.
Do not get bottled water Instead of bottled water get a reusable container to carry water. Also you can get a filter to make your home tap taste more like bottled water. It is definitely more cost efficient.
