Chicken tractors
The name "chicken tractor" is somewhat misleading, since no conventional motorized devices are used. A chicken tractor is little more than an open-bottom cage for chickens, which is light enough to be moved on the ground from location to another.

The chickens live in the chicken tractor and scratch, eat, and defecate on the ground surface. This process turns over the shallow surface, hence the 'tractor' reference. As the surface is sufficiently worked by the chickens, the tractor is moved to another space, repeating the process. The consumption of plants, seeds, and insects reduces plant growth and insect population, and the defecation nourishes the soil. Conventional chicken houses produce a volume of chicken waste with very high Nitrate concentration, which will burn many plants if used directly and therefore must be composted. The chicken tractor eliminates these handling and processing needs.

A chicken tractor will work on any flat surface with a substrate that supports plants and insects. Its main benefits are that it is a means of having free-range chickens and its attended benefits, but with better control/protection of the chickens. Moving it around permits more localized vegetation management, and keeps chickens out of gardens.

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.
