1. HAVE A CONTAINER YOU BRING EVERYWHERE. If you travel by foot or by bike, take along a container in your backpack or panier everywhere you go. This will prepare you for leftovers at potlucks, dinners out, cookies your friends want to give you, and bulk food you want to purchase. If you drive, have containers in your car always.
Types of containers:
--Glass jars that you cleaned after consuming the contents (spagetti sauce, peanut butter, pickles...), I like glass because it doesn't leak like plastic, the disadvantage is that it can splinter and break.
--Tupperwear containers. These are often made of plastic, plastic is derived from oil, and can overtime leach into your food. To minimize plastice contamination do not heat your food in plastic, don't use harsh cleaners on your plastic. If you have a glass container with a plastic lid, take the lid off when you are heating your food.
--Use your pottery skills to make your own pot with lid. How cool is that? Connect yourself with your container by creating it. Creating useful things brings great joy to life.

2. BRING A MUG, CHOPSTICKS AND SPORK EVERYWHERE. A couple other items to pack in your bag or vehicle. This will prevent using paper and styropoison cups, the spork will be good for both soup and spagetti, reusing your own chopsticks will reduce deforestation-- and if the mug is too bulky, you can use your glass jar as both a mug and a leftover container--just don't get burned. Wear gloves or something.

3. COMMIT TO SAVING THE EARTH WITH A FRIEND. If you want to stay committed and motivated peer pressure is a great way to do so. Commit to doing good with a friend so that you will feel motivated to ride your bike instead of drive, reuse instead of dispose, feel like part of something instead of isolated.
