and advanced housing technologies have become available, the
very idea of what a house or a building complex is has begun
a house or building can regulate its own temperature, recycle
waste, provide alternative
energy, and even produce food and water. This kind of
house is not just a roof to live under, it's an entire ecosystem
that can support all aspects of human life.
of this ideal is still fairly rare, but there are many housing
developments of varying size that are heading in this direction.

to reduce its environmental impact.
China is also working hard to develop green communities.
rather than making existing cities and communities more efficient
they are building whole new green
cities. China has two such projects in development, which
stand in stark contrast to other cities in China, many of
which are notorious for having poor environmental records.
As architects go green worldwide, other examples of green buildings are currently in the making.
Earthships designed and built by architect Mike Reynolds in New Mexico, for example, take environmental sustainability to the extreme, and are virtually self sustaining, requiring little in the
way of outside utilities and providing many basics like food,
water, and heat year round.
Many innovators are pushing the boundaries with green buildings,
but governments are becoming more active too. Several government
programs provide incentives and guidelines, such as LEED
in North America, for green buildings and green communities,
and to encourage builders and architects to build with environmental
sustainability in mind.
