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.

Selected article

The World Without Us is a non-fiction book about what would happen to the natural and built environment if humans suddenly disappeared, written by American journalist Alan Weisman and published by St. Martin's Thomas Dunne Books. It is a book-length expansion of Weisman's own February 2005 Discover article "Earth Without People". Written largely as a thought experiment, it outlines, for example, how cities and houses would deteriorate, how long man-made artifacts would last, and how remaining lifeforms would evolve. Weisman concludes that residential neighborhoods would become forests within 500 years, and that radioactive waste, bronze statues, plastics, and Mount Rushmore would be among the longest lasting evidence of human presence on Earth.

The author of four previous books and numerous articles for magazines, Weisman traveled around the world to interview academics, scientists and other authorities. He used quotations from these interviews to explain the effects of the natural environment and to substantiate predictions. The book has been translated and published in many countries. It was successful in the U.S., reaching #6 on the New York Times Best Seller list and #1 on the San Francisco Chronicle Best-Sellers list in September 2007. It ranked #1 on Time and Entertainment Weekly's of 2007.

The passenger pigeon was a species of pigeon that was once the most common bird in North America. It is estimated that there were as many as five billion passenger pigeons in the United States at the time Europeans colonized North America. They lived in enormous flocks, and during migration, one could see flocks of them a mile (1.6 km) wide and 300 miles (500 km) long, taking several days to pass and probably containing two billion birds. The species had not been common in the Pre-Columbian period, until the devastation of the American Indian population by European diseases.

Over the 19th century, the species went from being one of the most abundant birds in the world to extinction. At the time, passenger pigeons had one of the largest groups or flocks of any animal, second to only the desert locust.

Some decimation in numbers occurred as a result of loss of habitat, when the Europeans started settling further inland. However, the primary factor emerged when pigeon meat was commercialized as a cheap food for slaves and the poor in the 19th century, resulting in hunting on a massive scale. There was a slow decline in their numbers between about 1800 and 1870, followed by a catastrophic decline between 1870 and 1890, at the end of which they were rare and beyond the point of recovery. 'Martha', thought to be the world's last passenger pigeon, died on September 1, 1914 in Cincinnati.

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.

John James Audubon
A true conservationist is a man who knows that the world is not given by his fathers but borrowed from his children.
