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 living and non-living 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, and 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 from 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.

ASEAN Heritage Parks (AHP) are selected protected areas in the ASEAN region that are known for their unique biodiversity and ecosystems, wilderness and outstanding values in scenic, cultural, educational, research, recreational and tourism. Its vision is "An ASEAN region whose biological is conserved, sustainably managed and used, and equitably shared for the well-being of its peoples." The ASEAN Centre for Biodiversity (ACB) in the Philippines serves as the secretariat of the ASEAN Heritage Parks Programme.

The ASEAN Heritage Parks were established as the ASEAN national heritage parks and nature reserves on 29 November 1984 when only 6 countries: Brunei, Indonesia, Malaysia, Philippines, Singapore and Thailand were member countries. They became known by the present name on 18 December 2003 after Cambodia, Laos, Myanmar and Vietnam joined the organisation between 1995 and 1999. Through declarations, ASEAN member countries agreed that, "common cooperation is necessary to conserve and manage the parks for the development and implementation of regional conservation as well as regional mechanisms complementary to national efforts to implement conservation measures.

Ecological footprint analysis measures human demand on nature. It compares human consumption of natural resources with planet Earth's ecological capacity to regenerate them. It is an estimate of the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb the corresponding waste, given prevailing technology. Using this assessment, it is possible to estimate how many planet Earth's it would take to support humanity if everybody lived a given lifestyle. While the measure is widely used, some also criticize the approach.

In 2003, the average biologically productive area per person worldwide was approximately 1.8 global hectares (gha) per capita. The US footprint per capita was 9.6 gha, and that of Switzerland was 5.1 gha per person, whilst China's was 1.6 gha per person. The WWF claims that the human footprint has exceeded the biocapacity (the available supply of natural resources) of the planet by 25%.

Robert Sterling Yard in Yosemite National Park, 1920

Robert Sterling Yard (February 1, 1861 – May 17, 1945) was an American writer, journalist, and wilderness activist. Born in Haverstraw, New York, Yard graduated from Princeton University and spent the first twenty years of his career in the editing and publishing business. In 1915, he was recruited by his friend Stephen Mather to help publicize the need for an independent national park agency. Their numerous publications were part of a movement that resulted in legislative support for a National Park Service (NPS) in 1916. Yard served as head of the National Parks Educational Committee for several years after its conception, but tension within the NPS led him to concentrate on non-government initiatives. He became executive secretary of the National Parks Association in 1919.

Yard worked to promote the national parks as well as educate Americans about their use. Creating high standards based on aesthetic ideals for park selection, he also opposed commercialism and industrialization of what he called "America's masterpieces". These standards subsequently caused discord with his peers. After helping to establish a relationship between the NPA and the United States Forest Service, Yard later became involved in the protection of wilderness areas. In 1935, he became one of the eight founding members of The Wilderness Society and acted as its first president from 1937 until his death eight years later. Yard is now considered an important figure in the modern wilderness movement. (Full article...)

The Rainforest Alliance certification seal on a cup of coffee

The Rainforest Alliance is an international non-governmental organization (NGO) with staff in more than 20 countries and operations in more than 70 countries. It was founded in 1987 by Daniel Katz, an American environmental activist, who serves as the chair of the board of directors. The NGO states that its mission is "to create a more sustainable world by using social and market forces to protect nature and improve the lives of farmers and forest communities." Its work includes the provision of an environmental certification for sustainability in agriculture. In parallel to its certification program, the Rainforest Alliance develops and implements long-term conservation and community development programs in a number of critically important tropical landscapes where commodity production threatens ecosystem health and the well-being of rural communities.

The Rainforest Alliance is a product-oriented multistakeholder governance group combining the interests of companies, farmers, foresters, communities, and consumers to produce sustainable and harmonious goods. (Full article...)
