In my case, I refuse a vinyl bag when I pay the bill in the supermarket and jam foods into my own bag. I think simply it is obstacle for me because it is only one time to use it when I bring food into my room. That's reason. When I was a boy fresh from the country, I always receive the vinyl bags. But, I noticed they are no useful ways except to bring food and it is the cause to increase garbage in my room. So, I decided not to receive the vinyl bags. Also, I always buy compact fluorescent lamps when the previous one is no longer used. Actually, it is more expensive than incandescent light bulbs and it takes a little much time to be well-lighted.
But, the good points of compact fluorescent lamps are to save the more cost of energy consumption and to stand longer use than incandescent light bulbs. At first, I don't use them because incandescent light bulbs are cheaper than them overwhelmingly. However, their energy held only 2 months and decided to buy them. It was when I receive the electricity bills that I really feel the marvelous effect of them. I think you know what I want to say. Anyway, I think the most important thing to protect earth is not to share too heavy a burden for us. I don't think my action is too heavy. Refusing the vinyl bag and buying compact fluorescent lamps can't be too heavy. If you have other plans, please tell me.
