then join us and share your thoughts and techniques to save environment. It is the common understanding of natural environment that underlies environmentalism — a broad political, social, and philosophical movement that advocates various actions and policies in the interest of protecting what nature remains in the natural environment, or restoring or expanding the role of nature in this environme
nt. While true wilderness is increasingly rare, wild nature (e.g., unmanaged forests, uncultivated grasslands, wildlife, wildflowers) can be found in many locations previously inhabited by humans. Goals commonly expressed by environmental scientists include:
Reduction and clean up of pollution, with future goals of zero pollution;
Cleanly converting non-recyclable materials into energy through direct combustion or after conversion into secondary fuels;
Reducing societal consumption of non-renewable fuels;
Development of alternative, green, low-carbon or renewable energy sources;
Conservation and sustainable use of scarce resources such as water, land, and air;
Protection of representative or unique or pristine ecosystems;
Preservation of threatened and endangered species extinction;
The establishment of nature and biosphere reserves under various types of protection; and, most generally, the protection of biodiversity and ecosystems upon which all human and other life on earth depends. Very large development projects - megaprojects - pose special instructions and risks to the natural environments. Major dams and power plants are cases in point. The challenge to the environment from such projects is growing because more and bigger megaprojects are being built, in developed and developing nations alike.
