The natural environment comprises all naturally occurring surroundings and conditions in which living things grow and interact on Earth. These include complete landscape units that function as natural systems without major human intervention, as well as plants, animals, rocks, and natural phenomena occurring within their boundaries. They also include non-local or universal natural resources that lack clear-cut boundaries, such as air, water and climate.

The concept of the natural environment can be distinguished by components:

As human population numbers increase and as humans continue to evolve, human activity modifies the natural environment at a rapidly increasing rate, producing what is referred to as the built environment. The potential of the natural environment to sustain these anthropogenic changes while continuing to function as an ecosystem is an issue of major worldwide concern. Key environmental areas of interest include climate change, water supply and waste water, air pollution, waste management and hazardous waste, and land use issues such as deforestation, desertification, and urban sprawl.

Selected article

Merchants of Doubt is a 2010 book by the American science historians Naomi Oreskes and Erik M. Conway. It identifies parallels between the climate change debate and earlier controversies over tobacco smoking, acid rain and the hole in the ozone layer. Oreskes and Conway write that in each case "keeping the controversy alive" by spreading doubt and confusion after a scientific consensus had been reached, was the basic strategy of those opposing action. In particular, they say that Fred Seitz, Fred Singer, and a few other contrarian scientists joined forces with conservative think tanks and private corporations to challenge the scientific consensus on many contemporary issues.

Most reviewers received it favourably. One reviewer said that Merchants of Doubt is exhaustively researched and documented, and may be one of the most important books of 2010. Another reviewer saw the book as his choice for best science book of the year. Philip Kitcher in Science says Merchants of Doubt is a "fascinating and important study". The book was made into a film, Merchants of Doubt, directed by Robert Kenner, released in 2014.

Selected biography

Amory Lovins
Amory Bloch Lovins (November 13, 1947 - ) is Chairman and Chief Scientist of the Rocky Mountain Institute, a MacArthur Fellowship recipient (1993), and author and co-author of many books on renewable energy and energy efficiency.

Lovins has worked professionally as an environmentalist and an advocate for a "soft energy path" for the United States and other nations. He has promoted energy-use and energy-production concepts based on conservation, efficiency, the use of renewable sources of energy, and on generation of energy at or near the site where the energy is actually used.

Lovins has provided expert testimony in eight countries and more than 20 US states, briefed 19 heads of state, and published 29 books (including Winning the Oil Endgame, Factor Four with Hunter Lovins and Ernst Ulrich von Weizsäcker, and Natural Capitalism with Hunter Lovins and Paul Hawken).

Nanotechnology refers broadly to a field of applied science and technology whose unifying theme is the control of matter on the molecular level in scales smaller than 1 micrometre, normally 1 to 100 nanometers, and the fabrication of devices within that size range. Nanopollution is the result of waste generated by nanotechnology and has implications on the wider environment.

Selected quote

Kofi Annan
All our efforts to defeat poverty and pursue sustainable development will be in vain if environmental degradation and natural resource depletion continue unabated.
[[Kofi Annan

"The Wildlife Enforcement Monitoring System will provide the platform for our enforcement agencies to collect and share information on the trends and patterns of wildlife crime. Moreover, the cross-border nature of wild life crime underscores the need to enhance cooperation among our governments and to pool financial and human resources. I am confident that these measures will go a long way in enhancing our capacity to protect our wildlife resources.” - Mwai Kibaki.]]
