What are some ways to reduce our Ecological footprint? (It's a project!)?

Recycle, compost and cut down on needless spending, buy local produce, dont buy stuff produced overseas, grow your own vege, have your own chickens for eggs, build a windmill to generate your own power, use solar energy, fully insulate your home to cut down the power used to heat it, use energy efficient lightbulbs, learn to cook in the microwave. It uses less power than a conventional oven, walk or cycle instead of using the car, dont fly, use environmentally friendly household products. I could go on. :)
