Introduction

A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment.

The term environment can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency.

Apples are among the most wasted foods in the UK - 190,000 tonnes per year are thrown away.
Food waste in the United Kingdom has been identified as a considerable problem and has been the subject of ongoing media attention, intensifying with the launch of the "Love Food, Hate Waste" campaign in 2007. 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,[d] 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.

Selected biography

Lester Brown
Lester Russel Brown (born March 28, 1934) is a United States environmental analyst, founder of the Worldwatch Institute, and founder and president of the Earth Policy Institute, a nonprofit research organization based in Washington, D.C. BBC Radio commentator Peter Day calls him "one of the great pioneer environmentalists."

Brown is the author or co-author of over 50 books on global environmental issues and his works have been translated into more than forty languages. His most recent book is World on the Edge: How to Prevent Environmental and Economic Collapse (2011). Brown emphasizes the geopolitical effects of fast-rising grain prices noting that "the biggest threat to global stability is the potential for food crises in poor countries," and one that could "bring down civilization".

The recipient of 26 honorary degrees and a MacArthur Fellowship, Brown has been described by the Washington Post as "one of the world's most influential thinkers". As early as 1978, in his book The Twenty-Ninth Day, he was already warning of "the various dangers arising out of our manhandling of nature... by overfishing the oceans, stripping the forests, turning land into desert." In 1986, the Library of Congress requested his personal papers noting that his writings "have already strongly affected thinking about problems of world population and resources," while president Bill Clinton has suggested that "we should all heed his advice."

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 organization

Logo for Green Peace
Greenpeace, originally known as the Greenpeace Foundation, is an international environmental organization founded in Vancouver, British Columbia, Canada, in 1971. It is best known for its campaigns against nuclear weapons and campaigning against whaling. In later years, the focus of the organization turned to other environmental issues, including bottom trawling, global warming, ancient forest destruction, nuclear power, and genetic engineering. Greenpeace uses direct action, lobbying and research to achieve its goals. Greenpeace has national and regional offices in 46 countries worldwide, all of which are affiliated to the Amsterdam-based Greenpeace International.

The global organization receives its income through the individual contributions of an estimated 3 million financial supporters, as well as from grants from charitable foundations, but does not accept funding from governments or corporations. It is often the subject of criticism and ridicule for supposedly over-the-top protesting.

On its official website, Greenpeace defines its mission as the following:

Selected quote

Mother Teresa
There must be a reason why some people can afford to live well. They must have worked for it. I only feel angry when I see waste. When I see people throwing away things we could use.
