Introduction

Land management has preserved the natural characteristics of Hopetoun Falls, Australia while allowing ample access for visitors.

The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components:

In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams and the works of mound-building termites are thought of as natural.

People cannot find absolutely natural environments on Earth, naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. The massive environmental changes of humanity in the Anthropocene have fundamentally effected all natural environments including: climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.

Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming is a 2010 non-fiction book by American historians of science Naomi Oreskes and Erik M. Conway. It identifies parallels between the global warming controversy and earlier controversies over tobacco smoking, acid rain, DDT, 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 show 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.

Some of the book's subjects have been critical of the book, but most reviewers received it favorably. It was made into a film, Merchants of Doubt, directed by Robert Kenner, released in 2014. (Full article...)

Toyota Prius is one of the first mass-produced and marketed hybrid electric vehicles. Hybrid technology allows the vehicle to use both gasoline and electricity, thus reducing fuel consumption. It also reduces the amount of hydrocarbon emissions in the form of escaped gasoline vapour.

Sumaira Abdulali, born 22 May 1961 is an environmentalist from Mumbai, India, founder of the NGO Awaaz Foundation and convenor of the Movement against Intimidation, Threat and Revenge against Activists (MITRA). She was co-chairman of the Conservation Subcommittee and honorary secretary of Asia's oldest and largest environmental NGO, the Bombay Natural History Society, and was a Governing Council Member between 2008 and 2021.

Through legal interventions, advocacy and public campaigns, contribution to documentary films, television debates and press articles she has successfully mainstreamed and built consciousness about previously unknown environmental hazards, notably noise pollution and sand mining, and has won national and International awards for her work. She also set up the first network for protection of activists in India after an attack on her by the sand mafia is 2004. (Full article...)

The Global Footprint Network was founded in 2003 and is an independent think tank originally based in the United States, Belgium and Switzerland. It was established as a charitable not-for-profit organization in each of those three countries. Its aim is to develop and promote tools for advancing sustainability, including the ecological footprint and biocapacity, which measure the amount of resources we use and how much we have. These tools aim at bringing ecological limits to the center of decision-making. (Full article...)
