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.

Nissan Leaf
The Nissan Leaf is a compact five-door hatchback electric car manufactured by Nissan and introduced in Japan and the United States in December 2010, followed by various European countries and Canada in 2011. The US Environmental Protection Agency official range for the 2016 model year Leaf with the 30 kWh battery is 172 km (107 miles) on a full battery charge, while the trim with the smaller 24 kWh battery is 135 km (84 miles), the same as the 2014/15 model year.

As of December 2015, the Nissan Leaf is the world's all-time best selling highway-capable all-electric car. Leaf global sales passed the 200,000 unit milestone by early December 2015, five years after its introduction. As of November 2015, the top markets for Leaf sales are the United States with over 88,000 units sold, followed by Japan with about 57,000 units, and Europe with about 48,000 Leafs. As of September 2015, the European market was led by Norway with almost 15,000 new units, and the UK with about 11,500 units delivered.

As an all-electric car, the Nissan Leaf produces no tailpipe pollution or greenhouse gas emissions at the point of operation, and contributes to reduced dependence on petroleum. Among other awards and recognition, the Nissan Leaf won the 2010 Green Car Vision Award, the 2011 European Car of the Year, the 2011 World Car of the Year, and the 2011–2012 Car of the Year Japan.

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.

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).

Coral bleaching refers to the loss of color of corals due to stress-induced expulsion of symbiotic unicellular algae. It can be caused by sedimentation, change in pH, change in water temperature, or pathogen infections. When coral bleaching occurs, the productivity of the coral reefs are lost.

Selected organization

The Nature Conservancy is a US charitable environmental organization that works to preserve the lands and waters on which all life depends. Founded in 1951, The Nature Conservancy works in more than 30 countries. The Conservancy has over one million members, and has protected more than 119 million acres of land and 5,000 miles of rivers worldwide. The Nature Conservancy also operates more than 100 marine conservation projects globally.

The Nature Conservancy rates as one of the most trusted national organizations in Harris Interactive polls every year since 2005. Forbes magazine rated The Nature Conservancy's fundraising efficiency at 88% in its 2005 survey of the largest U.S. charities.

The organization was criticized for being too close to business, questionable resale of lands, its position on animal rights, and the conservation of land, plants and animals restricts the ability for farmers to do so responsibly.
