Refimprove date June 2007 Ecological health or ecological integrity or ecological damage are the symptoms of an ecosystem s pending loss of carrying capacity , its ability to perform ecological services , or a pending ecocide , due to cumulative causes such as pollution . It can also be defined in regards to farming so as to minimize the negative effects of agricultural practices. The term health is intended to evoke human environmental health concerns, which are often closely related but as a part of medicine not ecology . As with ecocide , that term assumes that ecosystems can be said to be alive see also Gaia philosophy on this issue . While the term integrity or damage seems to take no position on this, it does assume that there is a definition of integrity that can be said to apply to ecosystem s. The more political term ecological wisdom refers not only to recognition of a level of health, integrity or potential damage, but also, to a decision to do nothing more to harm that ecosystem or its dependents.

Ecological self is central to the school of Experiential Deep Ecology , which, based on the work of Norwegian philosopher Arne N ss , argues that through the process of self actualisation, one transcends the nations of the individuated egoic self and arrives at a position of an ecological self. So long as one is working within the narrower concept of self, N ss argues, environmentally responsible behaviour is a form of altruism, a doing good for the other , which historically has been a precarious ethical basis, usually involved in exhorting others to be good . N ss argues that in his Ecosophy , the enlargement of the ego self to the eco self results in environmentally responsible behaviour as a form of self interest. Warwick Fox argued that N ss s philosophy was based upon a variety of transpersonal ecology in which self interest was firmly embedded within the interest of the ecommunity ecosphere of which the self was eternally embedded ref Fox, Warwick 1990 .

Ecological Building is both a design process and the structure that is a result of such a design process. The Ecological Building design process is a modern architecture variant of permaculture design. An Ecological Building is a structure that is designed to create and sustain mutually beneficial relationships with all of the elements of its local ecology . A building s local ecology, or environment, is made up of particular physical and biological elements and their interactions. The abiotic , or physical elements are defined by the local geology and the local climate . The local geology is defined by the soil type, substrata gardening substrata , local land use , and water patterns of the site and its surroundings. The local climate is made up of the weather patterns, wind patterns, solar patterns, and pollution patterns for the site and its surroundings. The biotic material biotic or living elements are all of the local species and local ecosystems including humans and urban ecologies that interact with the site. This concept is distinctly different from green building , or sustainable architecture where the goal is to minimize the negative environmental impact of buildings ref sustainable architecture Wikipedia August 21, 2007 ref . Ecological building is a positive design goal that sets out to increase beneficial interactions, whereas green building is a negative design outlook that seeks only the reduction of negative interactions. Inherent in green building is the assumption that any human interaction with a site is unavoidably negative, and that mitigating these negative impacts is the best that is possible. With Ecological Building, the designer acknowledges that humans can play an integral, beneficial role in improving and sustaining the health and vitality of their local ecology.

Ecological indicators are used to communicate information about ecosystems and the impact human activity has on ecosystems to groups such as the public or government policy makers.

Unreferenced date March 2007 An ecological island is not necessarily an island surrounded by water, but is an area of land, isolated by natural or artificial means from the surrounding land, where a natural micro habitat exists amidst a larger differing ecosystem . Also, in artificial ecological islands also known as mainland islands all non native species at least predator species have been eradicated, native species are reintroduced and nurtured, and the natural or artificial border is maintained to prevent reintroduction of non native species. The ultimate goal is to recreate an ecological microcosm of the country as a whole as it was before human arrival. There is usually provision for controlled public access, and scientific study and research. The definition does not include land within a fence erected to protect farm animals from wild predators protect a specific species from specific predators exclude farm animals only exclude native animals although some native animals, weka for example, may need to be excluded during a species recovery phase . Background The concept of mainland islands was pioneered in New Zealand and arose mainly from the particular circumstances of that country s history.

An ecological deficit occurs when the Footprint of a population exceeds the biocapacity of the area available to that population. Conversely, an ecological reserve exists when the biocapacity of a region exceeds its population s Footprint. If there is a regional or national ecological deficit, it means that the region is either importing biocapacity through trade or liquidating regional ecological assets. In contrast, the global ecological deficit cannot be compensated through trade, and is therefore equal to overshoot. ref cite web title Global Footprint Network Glossary url http www.footprintnetwork.org gfn sub.php?content glossary accessdate 2008 11 02 ref See also Carrying capacity Ecological debt Greenhouse debt Material efficiency Natural capital References reflist modelling ecosystems expanded other Category Biogeography Category Environment Category Sustainability et koloogiline defitsiit eu Defizit ekologiko ... more details

Ecological imperialism is the idea that the true reason European settlers were so successful in the colonization effort was their introduction of animals, plants, and especially disease to new territories. The many pathogens they carried with them adversely affected the native populations of North America, Australia, and Africa, and were far more destructive than weaponry it is estimated that disease wiped out up to 90 95 percent of indigenous people in some locations. Ecological imperialism also argues that the disregard colonists had for the environments they were invading upset the natural balance of the established ecological system. Cortes and the Aztecs In the early 16th century, Spanish conquistador Hernan Cortes de Monroy y Pizarro led an expedition to what is now Mexico, which resulted in the total destruction of the Aztec Empire within just two years February 1519 August 1521 . Notwithstanding the Europeans superior weaponry, it is believed that the arrival of smallpox in the Americas in 1520 weakened the resistance the Aztecs people were able to mount. The New World In 1608, English settlers arrived in North America and established the Jamestown colony in Virginia. Though at first it seemed the colonists would not survive the harsh conditions of the New World, ultimately it was the natives who could not survive the diseases of the Old World. The colonizers brought along plants and animals new to the Americas, some by design and others by accident.

Ecological forecasting uses knowledge of physics, ecology and physiology to predict how ecosystem s will change in the future in response to environmental factors such as climate change . The ultimate goal of the approach is to provide people such as resource managers and designers of marine reserve s with information that they can then use to respond, in advance, to future changes, ref name Clark et al. 2001 Clark et al. 2001 ref a form of adaptation to global warming . One of the most important environmental factors for organisms today is global warming . Most physiological processes are affected by temperature , and so even small changes in weather and climate can lead to large changes in the growth, reproduction and survival of animals and plants.
