I was not aware of some of the options for disposing of more complex materials (including light bulbs, batteries, and other items) until seeing some of these separated bins at our Home Depot. For the past few months now, I have made sure to put aside those items as they stop working and make a quick trip over to drop them off.
Our apartment complex has recycling bins in community mail areas, encouraging recycling directly at the source, where there is a high potential for mass paper waste. This has been an easy way to help residents responsibly dispose of unneeded letters and other mail that may otherwise be thrown away with regular trash.
We noticed these earthships while driving through the state of New Mexico. Earthships are incredibly well designed, innovative, low-impact homes. They generally offer a multitude of sustainable features, are built with sustainable materials, designed for efficient heating and cooling, harvest both energy and water, and utilize a great variety of other friendly practices.
Much of my area has problems with low rainfall and drought. As a landscaping alternative, many houses use clever designs with drought resistant plants, or low water / rock designs such as this one. It is still aesthetically pleasing, and it helps the overall community in trying times.
