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

Merchants of Doubt is a 2010 book by the American science historians Naomi Oreskes and Erik M. Conway. It identifies parallels between the climate change debate and earlier controversies over tobacco smoking, acid rain and the hole in the ozone layer. Oreskes and Conway write that in each case "keeping the controversy alive" by spreading doubt and confusion after a scientific consensus had been reached, was the basic strategy of those opposing action. In particular, they say that Fred Seitz, Fred Singer, and a few other contrarian scientists joined forces with conservative think tanks and private corporations to challenge the scientific consensus on many contemporary issues.

Most reviewers received it favourably. One reviewer said that Merchants of Doubt is exhaustively researched and documented, and may be one of the most important books of 2010. Another reviewer saw the book as his choice for best science book of the year. Philip Kitcher in Science says Merchants of Doubt is a "fascinating and important study". The book was made into a film, Merchants of Doubt, directed by Robert Kenner, released in 2014.

Although the company is headquartered in Canada and the car manufactured in Canada, the vehicle was first introduced in United States because at the time of vehicle's design phrase, Canadian laws prevents this car to be driven on the roads.

Were we and the rest of the back-boned animals to disappear overnight, the rest of the world would get on pretty well.
