If you buy refrigerated tofu in a plastic container from the store, it’s often packaged in water to help keep it fresh. The directions call for you to drain the water before you slice the tofu to use for cooking. Did you know you can use the leftover tofu water in the container for baking? Much like the water in cans of chickpeas, called “aquafaba,” tofu water can be used as a replacement for eggs in baking. Use 3 to 4 tablespoons of tofu water for every egg in a recipe.

The Center for Energy and Climate Solutions, a nonprofit organization that works toward practical solutions to climate change, studied the eco-impact of e-commerce shopping. It found an extreme difference between shipping overnight air rather than ground shipping methods. The less-expensive (and slightly slower) ground shipping method uses just 1/10th of the energy consumption of planes. The greenest choice of all is walking to your local store and picking it up yourself.

While munching on an organic apple during your drive to work, you may think it’s perfectly fine to toss the core out the window of your car. It’s 100 percent biodegradable, and it may give a wild animal something to eat, right? But while the apple core is less polluting than, say, a candy wrapper, it’s still trash. Wild animals who find the apple core will discover it by the road, where they are in danger of being struck by a car. There is no appropriate litter to discard from your car, so dispose of all of it -- including apple cores -- in the compost, recycling bin or trash can.
