There are so many ways each of us can protect our environment AND reduce carbon emissions! Something I do when I walk my dogs is pick up their poop and any litter we find. Dog poop in urban areas is unpleasant to come across, and it contributes to poor water quality, so it's better to bag it. I often find cans and bottles along the road in my neighborhood when I'm walking my dogs, and I always pick up what I can carry. Then I put it in the recycling can. Recycling saves energy and resources avoids the production of a lot of carbon emissions.
We also conserve energy at home by setting the thermostat a little higher in the summer (a little lower in the winter), and when we are not going to be home. We also turn-off or unplug devices when we aren't using them, and try to replace appliances with the most efficient ones we can buy. We use cold water only for laundry and hang at least half our laundry outside to air dry.
We are eating less meat, more veggies, and supporting more local businesses, including our CSA farmer. And I still feed the worms with my compost bins. I know there's more I could do, and I will keep doing more. I also teach college students about all these issues and more. With more of us doing small things, and more of us compelling our elected officials, at all levels to do more, I know we will do the right thing.
