CCAT natural paint project
CCAT natural paint project. The Campus Center for Appropriate Technology (CCAT) at Humboldt State University in Arcata, CaliforniaW is completely remodeling the inside of their building. When all of the construction is finished the entire interior of the house will need to be painted. As an ENGR 305 project, Spring 2007, Andrea Lanctot and Jill Anderson have decided to make all the interior paints from scratch using safe natural ingredients.

The project has four main goals. The first is to research natural paint ingredients, recipes, and techniques. The second is to make several of the recipes and test the paints for color, durability, and texture. The third is to choose paints from the tests for the new CCAT house and apply them to the interior. The last goal is to test the final application with the test of time. See natural paint basics for background research on ingredients, types and advantages/disadvantages of natural paint.

The WaterPod's only cooking appliance for the entire summer voyage. Discovery News says, "If rising ocean levels force us to figure out how to float, it might not be an entirely bad thing. Especially if the food tastes like this."

E. F. Schumacher
The system of nature, of which man is a part, tends to be self-balancing, self-adjusting, self-cleansing. Not so with technology.

You can have a green Christmas.
Green living (or sustainable living) is about practical choices, large and small, to preserve the earth and have a better quality of life. It is a lifestyle that attempts to reduce an individual's or society's use of the Earth's natural resources and his or her own resources.

In order to make sustainable choices, it is very helpful to have solid, reliable information that tells us which behaviors are sustainable and which are unsustainable. In quantitative terms, which actions will make the greatest difference, and should be prioritized. Green living can be high tech (buying a hybrid vehicle), low tech (green cleaning, or completely "back to nature." It can be smart grid or off the grid. Sustainable city living explains some of the areas of action for a city dweller.

Practitioners of sustainable living often attempt to reduce their carbon footprint by altering methods of transportation, energy consumption and diet. Proponents of sustainable living aim to conduct their lives in ways that are consistent with sustainability, in natural balance and respectful of humanity's symbiotic relationship with the Earth's natural ecology and cycles. The practice and general philosophy of ecological living is highly interrelated with the overall principles of sustainable development.
