Environment

Devil's Punchbowl Waterfall, New Zealand.
The natural environment comprises all naturally occurring surroundings and conditions in which living things grow and interact on Earth. These include complete landscape units that function as natural systems without major human intervention, as well as plants, animals, rocks, and natural phenomena occurring within their boundaries. They also include non-local or universal natural resources that lack clear-cut boundaries, such as air, water and climate.

The concept of the natural environment can be distinguished by components:

As human population numbers increase and as humans continue to evolve, human activity modifies the natural environment at a rapidly increasing rate, producing what is referred to as the built environment. The potential of the natural environment to sustain these anthropogenic changes while continuing to function as an ecosystem is an issue of major worldwide concern. Key environmental areas of interest include climate change, water supply and waste water, air pollution, waste management and hazardous waste, and land use issues such as deforestation, desertification, and urban sprawl.

Three Gorges Dam on the Yangtze River, China
The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in the Yiling District of Yichang, in Hubei province, China. The Three Gorges Dam is the world’s largest capacity hydroelectric power station with a total generating capacity of 18,200 MW.

The dam body was completed in 2006. Except for a ship lift, the originally planned components of the project were completed on October 30, 2008, when the 26th turbine in the shore plant began commercial operation. Each turbine has a capacity of 700  MW. Six additional turbines in the underground power plant are not expected to become fully operational until 2012. Coupling the dam's thirty-two main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will eventually reach 22,500 MW.

As well as producing electricity, the dam increases the Yangtze River's shipping capacity, and reduces the potential for floods downstream by providing flood storage space. The Chinese government regards the project as a historic engineering, social and economic success, with the design of state-of-the-art large turbines, and a move toward limiting greenhouse gas emissions. However, the dam flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides. The dam has been a controversial topic both in China and abroad.

Selected biography

Buckminster Fuller
Richard Buckminster “Bucky” Fuller (July 12, 1895 – July 1, 1983) was an American visionary, designer, architect, poet, author, and inventor.

Throughout his life, Fuller was concerned with the question "Does humanity have a chance to survive lastingly and successfully on planet Earth, and if so, how?" Considering himself an average individual without special monetary means or academic degree, he chose to devote his life to this question, trying to find out what an individual like him could do to improve humanity's condition that large organizations, governments, or private enterprises inherently could not do.

Fuller published more than 30 books, inventing and popularizing terms such as "Spaceship Earth", ephemeralization, and synergetic. He also developed numerous inventions, mainly architectural designs, the best known of which is the geodesic dome. Carbon molecules known as fullerenes were later named by scientists for their resemblance to geodesic spheres.

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.

Selected organization

The Brundtland Commission, formally the World Commission on Environment and Development (WCED), known by the name of its Chair Gro Harlem Brundtland, was convened by the United Nations in 1983. The commission was created to address growing concern "about the accelerating deterioration of the human environment and natural resources and the consequences of that deterioration for economic and social development." In establishing the commission, the UN General Assembly recognized that environmental problems were global in nature and determined that it was in the common interest of all nations to establish policies for sustainable development.

The Report of the Brundtland Commission, Our Common Future, was published in 1987. It was welcomed by the General Assembly in its resolution 42/187. The report deals with sustainable development and the change of politics needed for achieving that. The definition of this term in the report is quite well known and often cited:

"Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts:
  • the concept of 'needs', in particular the essential needs of the world's poor, to which overriding priority should be given; and
  • the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future needs."

Selected quote

Margaret Thatcher
When you've spent half your political life dealing with humdrum issues like the environment, it's exciting to have a real crisis on your hands.
