edit   Environment 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: Complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, soil, rocks, atmosphere and natural phenomena that occur within their boundaries. Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity. 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.

A significant proportion of food waste is produced by the domestic household, which, in 2007, created 6,700,000 tonnes of food waste. Potatoes, bread slices and apples are respectively the most wasted foods by quantity, while salads are thrown away in the greatest proportion. A majority of wasted food is avoidable, with the rest being divided almost equally by foods which are unavoidable (e.g. tea bags) and unavoidable due to preference (e.g. bread crusts) or cooking type (e.g. potato skins). Reducing the amount of food waste has been deemed critical if the UK is to meet international targets on climate change, limiting greenhouse gas emissions, and meet obligations under the European Landfill Directive to reduce biodegradable waste going to landfill. Equally great emphasis has been placed on the reduction of food waste, across all developed countries, as a means of ending the global food crisis that leaves millions worldwide starving and impoverished. In the context of the 2007–2008 world food price crisis, food waste was discussed at the 34th G8 summit in Hokkaidō, Japan. UK prime minister Gordon Brown said of the issue "We must do more to deal with unnecessary demand, such as by all of us doing more to cut our food waste". In June 2009, then Environment Secretary Hilary Benn announced the government's "War on waste", a programme aimed at reducing Britain's food waste. edit   Did you know... ...that chlorofluorocarbons (CFCs) can cause ozone depletion, and the ozone hole needs to take more than a decade to recover? ...that the incandescent light bulb has an energy efficiency of only 5%, and the rest of the energy is used to generate heat rather than light? ... that the global ecological footprint is 1.8 global hectares (gha) per capita? ...that in 2004, the worldwide energy consumption of the human race was 15 TW (= 1.5 x 1013 W) with 86.5% from burning fossil fuel? edit   Current events June 10: Five hundred cattle die of neglect on West Australia property April 24: Power outage at Fukushima poses radioactive risk March 18: Australian Labor Party announces new Climate Change Policy March 18: Warming oceans make it harder for fish to breathe edit   Selected biography Arne Dekke Eide Næss (born January 27, 1912) is widely regarded as the foremost Norwegian philosopher of the 20th century, and is the founder of deep ecology. His philosophical work focused on Spinoza, Buddhism and Gandhi. Næss combined his ecological vision with Gandhian nonviolence and on several occasions participated in direct action. In 1970, together with a large number of demonstrators, he chained himself to rocks in front of Mardalsfossen, a waterfall in a Norwegian fjord, and refused to descend until plans to build a dam were dropped. Though the demonstrators were carried away by police and the dam was eventually built, the demonstration launched a more activist phase of Norwegian environmentalism. Næss had been a minor political candidate for the Norwegian Green Party and in 1939 he was the youngest person to be appointed full professor at the University of Oslo and the only professor of philosophy in the country at the time. In 1996, he won the Swedish Academy Nordic Prize, known as the 'little Nobel'. In 2005 he was decorated as a Commander with Star of the Royal Norwegian Order of St. Olav for socially useful work. edit   Selected picture An animated image showing projections of stratospheric ozone concentrations if chlorofluorocarbons (CFCs) had not been banned. CFCs and other halogenated ozone-depleting substances are mainly responsible for man-made chemical ozone depletion. Since the ozone layer absorbs UVB ultraviolet light, its depletion is expected to increase surface UVB levels, which could lead to damage, including increase in skin cancer. edit   Selected organization The International Union for Conservation of Nature and Natural Resources (IUCN) is an international organization dedicated to natural resource conservation. Previous names include World Conservation Union or International Union for the Preservation of Nature (IUPN). Founded in 1948, its headquarters is located in the Lake Geneva area in Gland, Switzerland. The IUCN brings together 83 states, 108 government agencies, 766 NGOs and 81 international organizations and about 10,000 experts and scientists from countries around the world. IUCN's mission is to influence, encourage and assist societies throughout the world to conserve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustainable. The first Director General of UNESCO, (Sir Julian Huxley), wishing to give UNESCO a more scientific base, sponsored a congress to establish a new environmental institution to help serve this purpose. At that first congress (held at Fontainebleau, France), on 5 October 1948, 18 governments, 7 international organizations, and 107 national nature conservation organizations all agreed to form the institution and signed a "constitutive act" creating an International Union for the Protection of Nature. From this beginning, the overriding strategy and policy of the institution has been to explore and promote mutually beneficial conservation arrangements that suit those promoting development as well as assisting people and nations to better preserve their flora and fauna. At all times, the institution (in all its forms) has heavily emphasised as a key operating principle the strong need to cater for and address the needs of local nations, communities and peoples, so that those nations, communities and peoples can take ownership of future, long term conservation goals and objects in their local areas: Protected areas and threatened species could most effectively be safeguarded if local people considered it in their own interest to do so. Working with rather than against local people became a major working principle for IUCN. — Page 61 The IUCN's World Conservation Strategy (1980) was founded upon this kind of principle, and clearly announced the IUCN's ambitions to more effectively enter into dialogue with the promoters of human development. The strategy was internationally applauded by many and served to secure the IUCN funds from several donors who didn't themselves feel they could open up effective dialogue in the world's developing countries, nor that United Nations organizations and international banks would effectively engage in such dialogue. The IUCN has now expanded into many of the nations around the world, making available the services of a large pool of mainly voluntary specialists, providing local level advice and conservation services, and expanding its networks of Committees and regional advisory bodies into increasing numbers of countries. The Union has three components: its member organizations, its 6 scientific commissions and its professional secretariat. edit   Selected quote edit   Main topics Natural environment Acid rain • Biodiversity • Climate change • Conservation • Deforestation • Desertification • Ecosystem • Environmental economics • Environmental law • Environmental policy • Environmental science • Environmentalism • Environmental technology • Global warming • Greenhouse gas • Green Politics • Lists (Books, Dates, Issues) • Ozone depletion • Recycling • Renewable energy • Soil retrogression and degradation • Sustainable development • Waste management edit   Things you can do This list is transcluded from the tasks list page.
