The most basic thing you can do to make your yard more sustainable is to start a compost pile. All you need to get started is some brown and green. So take your dead leaves and yard trimmings and start layering. Over time, add vegetable scraps, coffee grounds and egg shells and turn it occasionally to add air. Eventually you will have beautiful, rich soil that's perfect for planting a vegetable garden -- another thing you can do to create a more sustainable home. Kick it up a notch and add edible plants to your landscape. While you're at it, lose the grass and xeriscape your yard with drought-tolerant plant varieties. Less watering equals greater sustainability. You can also plant deciduous shade trees around your home to help with air conditioning bills. When they lose their leaves in the winter, they'll let in more light.
