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.

The dam in September 2009

The Three Gorges Dam (simplified Chinese: 三峡大坝; traditional Chinese: 三峽大壩; pinyin: Sānxiá Dàbà), officially known as Yangtze River Three Gorges Water Conservancy Project (simplified Chinese: 长江三峡水利枢纽工程; traditional Chinese: 長江三峽水利樞紐工程) is a hydroelectric gravity dam that spans the Yangtze River near Sandouping in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The world's 27th largest dam by reservoir volume, and the world's largest power station by installed capacity (22,500 MW), the Three Gorges Dam generates 95±20 TWh of electricity per year on average, depending on the amount of precipitation in the river basin. After the extensive monsoon rainfalls of 2020, the dam produced nearly 112 TWh in a year, breaking the previous world record of ~103 TWh set by the Itaipu Dam in 2016.

The dam's body was completed in 2006; the power plant became fully operational in 2012, when the last of the main water turbines in the underground plant began production. The last major component of the project, the ship lift, was completed in 2015. The dam, measuring 185 meters in height and 2,309 meters in width, significantly surpasses Brazil’s 12,600 MW Itaipu facility and is one of the world's largest hydroelectric plants.

ZENN (Zero Emission, No Noise) is a 2-seated car that runs solely on battery. It has a range of up to 60 km and does not exceed 40 km/h. The fuel economy is few cents per kilometer and the MSRP is $12,000.

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. Since 2000, British Columbia has allowed ZENN cars on its roads.

Suzuki in December 2009

David Takayoshi Suzuki CC OBC FRSC (born March 24, 1936) is a Canadian academic, science broadcaster, and environmental activist. Suzuki earned a PhD in zoology from the University of Chicago in 1961, and was a professor in the genetics department at the University of British Columbia from 1963 until his retirement in 2001. Since the mid-1970s, Suzuki has been known for his television and radio series, documentaries and books about nature and the environment. He is best known as host and narrator of the popular and long-running CBC Television science program The Nature of Things, seen in over 40 countries. He is also well known for criticizing governments for their lack of action to protect the environment.

A longtime activist to reverse global climate change, Suzuki co-founded the David Suzuki Foundation in 1990, to work "to find ways for society to live in balance with the natural world that does sustain us." The Foundation's priorities are: oceans and sustainable fishing, climate change and clean energy, sustainability, and Suzuki's Nature Challenge. The Foundation also works on ways to help protect the oceans from large oil spills such as the Deepwater Horizon oil spill. Suzuki has also served as a director of the Canadian Civil Liberties Association from 1982 to 1987. (Full article...)

Tallman Island plant

The New York City Department of Environmental Protection (DEP) is the department of the government of New York City that manages the city's water supply and works to reduce air, noise, and hazardous materials pollution.

Under a 1.3 billion dollar budget, it provides more than 1.1 billion US gallons (4,200,000 m3) of water each day to more than 9 million residents (including 8 million in the City of New York) through a complex network of nineteen reservoirs, three controlled lakes and 6,000 miles (9,700 km) of water mains, tunnels and aqueducts. DEP is also responsible for managing the city's combined sewer system, which carries both storm water runoff and sanitary waste, and fourteen wastewater treatment plants located throughout the city. DEP carries out federal Clean Water Act rules and regulations, handles hazardous materials emergencies and toxic site remediation, oversees asbestos monitoring and removal, enforces the city's air and noise codes, bills and collects on city water and sewer accounts, and manages citywide water conservation programs. Its regulations are compiled in title 15 of the New York City Rules. (Full article...)
