Buy a service, not a product: To reduce embodied carbon pollution and water consumption, think about buying someone a service - say a voucher for a massage, rather than a massaging appliance. Vouchers for other services, (such as gardening or housecleaning) or film and theatre tickets are also good. Beware gifts that will increase the recipient's motor travel.
Buy gift vouchers: Gift vouchers are a good thing for the environment. People use them to get exactly what they want. And they can use its value for a purchase in the store at any time after christmas. Make sure the validity is at least 6 months or a year, so that recipient will not forget to use it before it expires. (more tips follow)
Ecological dry toilets at Pedregal, a Permaculture Demonstration Center in Oaxaca, Mexico.
The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it. However, it is not a great risk compared to blackwater (sewage). Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants. |
