Environment Information
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.

The
Great Barrier Reef is the world's largest
coral reef system, composed of roughly 3,000 individual reefs and 900 islands that stretch for 2,600 kilometres (1,616 mi) and cover an area of approximately 344,400 km². The reef is located in the
Coral Sea, off the coast of
Queensland in northeast Australia. A large part of the reef is protected by the
Great Barrier Reef Marine Park.
The Great Barrier Reef's environmental pressures include lowered water quality from runoff including suspended sediment, excess nutrients, pesticides, and fluctuations in salinity. The effects of climate change, including increased temperatures, storms and coral bleaching. Cyclic outbreaks of the crown-of-thorns starfish, overfishing which disrupts food chains, and shipping routes which can result in oil spills or improper ballast discharge also damage the reef.

Selected biography
David Suzuki is a Canadian science
broadcaster and
environmental activist. Since the mid 1970s, Suzuki has become known for his TV and radio series and books about nature and the environment. He is best known as host of the popular and long-running
CBC Television science magazine,
The Nature of Things, seen in syndication in over 40 nations. He is well known for criticizing governments for their lack of actions to protect the environment.
Selected organization
The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body tasked to evaluate the risk of climate change caused by human activity. The panel was established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), two organizations of the United Nations. The IPCC shared the 2007 Nobel Peace Prize with former Vice President of the United States Al Gore.
One of the main activities of the IPCC is to publish special reports on topics where it supports the UN Framework Convention on Climate Change (UNFCCC), which is essentially the document behind the Kyoto Protocol. It bases its assessment mainly on peer reviewed and published scientific literature. The IPCC is only open to member states of the WMO and UNEP.
The stated aims of the IPCC are to assess scientific information relevant to:
- Human-induced climate change,
- The impacts of human-induced climate change,
- Options for adaptation and mitigation.
The IPCC does not carry out research, nor does it monitor climate or related phenomena. A main activity of the IPCC is publishing special reports on topics relevant to the implementation of the UN Framework Convention on Climate Change (UNFCCC), an international treaty that acknowledges the possibility of harmful climate change; implementation of the UNFCCC led eventually to the Kyoto Protocol. The IPCC bases its assessment mainly on peer reviewed and published scientific literature. The IPCC is only open to member states of the WMO and UNEP.
IPCC reports are widely cited in almost any debate related to climate change. National and international responses to climate change generally regard the UN climate panel as authoritative. The summary reports (i.e. Summary for Policymakers), which draw the most media attention, include review by participating governments in addition to scientific review.
Selected quote
| I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species. I realized that you humans are not actually mammals. Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment, but you humans do not. You move to an area, and you multiply and multiply, until every natural resource is consumed. The only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is? A virus. Human beings are a disease, a cancer of this planet.
— Agent Smith
