The science of changing the DNA of a plant or animal to produce desirable
characteristics. Examples of desirable characteristics include fast growth and
unusually large size. This is a very controversial science
that many believe has not been adequately tested and studied. In addition, not
everyone agrees that the plants and animals that are genetically engineered are
safe for humans to eat or safe for the environment if released.

Genetically Modified Organism. This is a plant or animal that has been genetically
engineered. Many industries support the development and use of GMOs while many
consumers and organizations question their safety and have called for adequate
and independent testing of GMO products. It is legal for farmers in the U.S.
and some other countries like Argentina to produce and sell certain GMOs for
human and animal consumption, but in other places like Europe and Japan, they
are banned until further testing can be done to prove they are safe.

A design, usually architectural, conforming to environmentally sound
principles of building, material and energy use. A green building, for example,
might make use of solar panels, skylights, and recycled building materials.

A building made with translucent (light transparent, usually glass or
fiberglass) walls conducive to plant growth.

The process that raises the temperature of air in the lower atmosphere
due to heat trapped by greenhouse gases, such as carbon
dioxide, methane, nitrous oxide, chloroflurocarbons, and ozone.

More Info:


Components of the atmosphere that contribute to the Greenhouse Effect,
the major natural greenhouses gases are water vapor, carbon dioxide, methane,
and ozone ,some greenhouse gases occur naturally in the atmosphere, while
others result from human activities such as burning of fossil fuel and coal.
