What are ways to be more "Green?"

Using homemade cleaners. I make my own laundry detergent (washing soda, borax, bar soap and water). It turns out to be about 2 cents per load of laundry. I use vinegar with maybe a squeeze of lemon or lime to make it smell better, as well as baking soda, etc. Also, when I prepare a meal I make enough to have leftovers or I make freezer meals. I live in an apartment so I do container gardening for some of my own spices, tomatoes, and a couple other small veggies. I NEVER wash a small load of laundry, I wait till we have a large load. In the spring and summer I use a clothes line and dry my clothes that way. In the winter and autumn I do a scaled down version to dry jeans and other heavy materials that fits in my apartment. I NEVER buy plastic bottles of water or juice. There's more, but the husband wants to use the computer.
