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

Invasive species are widespread non-indigenous species. The introduction of these non-indigenous species can be accidental or intentional. It can be damaging to the local ecosystem as invasive species compete resources with local species. Most of the time the non-native species cannot survive in the new environment and died out. However, there is a chance that they managed to survive and no natural predator in the new environment. This can wipe out local species as the population of the invasive species increases, thus negatively affecting biodiversity.

Scientists propose several mechanisms to explain invasive species, including species-based mechanisms and ecosystem-based mechanisms. It is most likely a combination of several mechanisms that cause an invasive situation to occur, since most introduced plants, biotic and animals do not become invasive.

Selected biography

David Suzuki is a Canadian science broadcaster and environmental activist. Since the mid 1970s, Suzuki has become known for his TV and radio series and books about nature and the environment. He is best known as host of the popular and long-running CBC Television science magazine, The Nature of Things, seen in syndication in over 40 nations. He is well known for criticizing governments for their lack of actions to protect the environment.

A false-color composite of global oceanic and terrestrial photoautotroph abundance, from September 1997 to August 2000. The picture shows the activity of photosynthesizing organisms in the biosphere. Many of these are used for ecosystem services which are natural processes relied upon by humans.

Selected organization

The World Wide Fund for Nature is an international non-governmental organization for the conservation, research and restoration of the natural environment, formerly named the World Wildlife Fund, which remains its official name in the United States and Canada. It is the world's largest independent conservation organization with over 5 million supporters worldwide, working in more than 90 countries, supporting 15,000 conservation and environmental projects around the world. It is the world's largest independent conservation organization with over 5 million supporters worldwide, working in more than 90 countries, supporting around 1300 conservation and environmental projects around the world. It is a charity, with approximately 60% of its funding coming from voluntary donations by private individuals. 45% of the fund's income comes from the United States, the United Kingdom, and the Netherlands.

The group says its mission is "to halt and reverse the destruction of our environment". Currently, much of its work focuses on the conservation of three biomes that contain most of the world's biodiversity: forests, freshwater ecosystems, and oceans and coasts. Among other issues, it is also concerned with endangered species, pollution and climate change.

Water and air, the two essential fluids on which all life depends, have become global garbage cans.
