You can have a Green Christmas.
You can have a Green Christmas. Often the best time of year for catching up with family and friends, it's also the biggest time of spending - on presents, food, alcohol, parties and holidays. Unfortunately, all of our spending and consumption results in significant environmental damage and carbon pollution. However, you don't have to be a scrooge to reduce your carbon footprint at Christmas. Here are tips for a more sustainable festive season.

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)

Muhammad Yunus at World Economic Forum in Davos, Switzerland, 25 January 2012
I avoid grandiose plans. I start with a small piece that I can do. I go to the root of the problem and then work around it. It's building brick by brick.

Estuaries and coastal waters are among the most productive ecosystems on Earth.
Water is vital for all known forms of life. Covering 71% of the Earth's surface, it is found mostly in oceans and other large water bodies. 1.6% of the total mass of the Earth's water is below ground in aquifers and 0.001% is in the air as vapor, clouds, and precipitation (rain, snow and sleet).

The Earth's water moves constantly through a cycle of evaporation and transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land - thus deforestation and other changes to land can have wide and long-lasting effects through their impact on the water cycle.

Some observers estimate that by 2025 more than half of the world population will be vulnerable to a lack of water. Appropriate water supply and water purification technologies can help.

HSU Chiapas Program 2010: Humboldt State University's 2010 summer immersion in Appropriate Technology and Spanish Language & Culture took place in San Cristóbal de las Casas, Chiapas, Mexico. In 2010, we worked with Otros Mundos and various community members in San Cristobal de las Casas and near Acteal to collaboratively build three improved cookstoves, three rainwater catchment systems, windbelt prototypes, microhydro power feasibility studies, and a biogas digestor.
