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.

The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is one of the main drivers of the negative impact of modern industrial agriculture on the environment. Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. Other agrochemicals, such as fertilizers, can also have negative effects on the environment.

The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices. Over time, repeat application of pesticides increases pest resistance, while its effects on other species can facilitate the pest's resurgence. Alternatives to heavy use of pesticides, such as integrated pest management, and sustainable agriculture techniques such as polyculture mitigate these consequences, without the harmful toxic chemical application.

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 biography - show another

Gary Edward Varner (March 10, 1957 – June 28, 2023) was an American philosopher specializing in environmental ethics, philosophical questions related to animal rights and animal welfare, and R. M. Hare's two-level utilitarianism. At the time of his death, he was an emeritus professor in the department of philosophy at Texas A&M University; he had been based at the university since 1990. He was educated at Arizona State University, the University of Georgia, and the University of Wisconsin–Madison; at Madison, where he was supervised by Jon Morline, he wrote one of the first doctoral theses on environmental ethics. Varner's first monograph was In Nature's Interests?, which was published by Oxford University Press in 1998. In the book, Varner defended a form of biocentric individualism, according to which all living entities have morally considerable interests.

Varner started a research project in 2001 that looked at animals in Hare's two-level utilitarianism. The project's initial monograph, Personhood, Ethics, and Animal Cognition, was released by Oxford in 2012. In the book, Varner moved away from his biocentrism, instead endorsing a developed version of Hare's ethics. Varner draws a distinction between persons, near-persons and merely sentient beings; although all are morally considerable, the lives of persons are of the most significance, and the lives of merely sentient beings are of the least. The practical consequences of this view, though initial comments were offered in Personhood, Ethics, and Animal Cognition, was to be explored in Sustaining Animals, with which Varner at one time had a contract with Oxford. His third book was Defending Biodiversity: Environmental Science and Ethics, co-authored with Jonathan Newman and Stefan Linquist, and published with Cambridge University Press. It was published in 2017. (Full article...)

Selected organization - show another

The Iranian Department of Environment (Persian: سازمان حفاظت محیط زیست) is a governmental organization, under the supervision of the president, that is responsible for matters related to safeguarding the environment.

The origins of the department can be traced back to the Hunting Club of Iran, established in 1956. Later, it developed into an organization overseeing hunting and fishing activities in the country. In 1971, the organization changed its name to its current one, and notably has hosted the Ramsar Convention on Wetlands of International Importance in the city of Ramsar on the same year.

Mother Teresa
There must be a reason why some people can afford to live well. They must have worked for it. I only feel angry when I see waste. When I see people throwing away things we could use.
