    • No radical political agenda, promote working to create change within existing social and political structures
    • Current economic growth can be sustained if environmental issues are managed by legal means or political agreement
    • Believe that the environment can be used if managed properly
  • Cornucopians
    • The world has infinite resources
    • They do not see environmental issues as problems because humans have always found a way out of difficulties in the past
    • New resources and technologies will solve any environmental problems as they are encountered
    • There is no need for a radical agenda, socio-economic or political reform
    • Growth and capitalism are the best ways to manage the free-market economy
  • The modern environmental movement was catalysed by Rachel Carson's book, Silent Spring, published in 1962
  • Silent Spring

    Warned of the effects of pesticides on insects, both pests and others, and how this was being passed along the food chain to kill other animals, including birds (hence a silent spring)
  • What really gained people's attention was her belief that pesticides such as DDT were finding their way into people and accumulating in fatty tissues, causing higher risks of cancer
  • Chemical industries tried to ban the book but many scientists shared her concerns and when an investigation, ordered by US president John F. Kennedy, confirmed her fears, DDT was banned
  • In the decades since the publication of Silent Spring, it has been criticized as scaremongering without enough scientific evidence. The banning of DDT may have caused more harm than good by allowing the mosquitoes that carry malaria to survive and so spread the disease causing millions of deaths
  • Al Gore, former US vice-president, was heavily influenced by the book to become involved in environmental issues, particularly with his documentary on climate change – An Inconvenient Truth, 2006
  • This raised awareness on climate change, then called global warming, and clearly stated that global climate change was a result of greenhouse gases released by human activities and that we had to act as this is a moral issue
  • George Bush's response to the documentary when he was president of the USA was 'Doubt it' and he later said that we should focus on technologies that enable us to live better lives and protect the environment
  • The Chisso Corporation built a chemicals factory in Minamata, Japan and was very successful for years. But a by-product was methylmercury which bioaccumulated in the bodies of humans, causing mercury poisoning
  • The villagers sued Chisso many times and asked for compensation, until the government finally had Chisso pay them compensation and treat their illnesses
  • In the early hours of the morning of 3 December 1984, in the centre of the city of Bhopal, India, in the state of Madhya Pradesh, a Union Carbide pesticide plant released 40 tonnes of methyl isocyanate (MIC) gas, immediately killing nearly 3,000 people and ultimately causing at least 15,000-22,000 total deaths. This has been called the Bhopal Disaster and is considered to be the world's worst industrial disaster
  • The people are still suffering till today
  • In 1986, at Chernobyl, the worst nuclear disaster ever occurred. This was a few miles north of Kiev, the capital of Ukraine (then part of the USSR) where an explosion and then fire resulted in a level 7 event (the highest)
  • The reactor vessel containing the uranium radioactive material split so exposing the graphite moderator to air which caused it to catch fire. The reactor went into uncontrollable meltdown and a cloud of highly radioactive material from this drifted over much of Russia and Europe as far west as Wales and Scotland
  • Fission products from the radioactive cloud, e.g. isotopes of caesium, strontium and iodine, have a long half-life and were accumulated in food chains
  • There is much debate about how many people have been affected by the radiation as long-term effects, such as cancers and deformities at birth, are difficult to link to one event
  • 31 workers died of radiation sickness as they were exposed to high levels in trying to shut down the reactor and some had a lethal dose of radiation within one minute of exposure
  • Estimates of later deaths vary but some state about 1,000 extra cases of thyroid cancer and 4,000 other cancers caused by the fallout cloud. Other estimates state that 1 million people will have died as a result of the disaster
  • Even today, the reactor is still dangerous. It was encased in a concrete shell but the other reactors continued to run until 2000. Now, a metal arch is being built as the concrete shell only has a lifetime of 30 years but estimates of the date of completion have been put back to 2016
  • In 2011, there was another nuclear accident at the Fukushima Daiichi nuclear plant in Japan. An earthquake set off a tsunami which caused damage resulting in meltdown of 3 reactors in the plant. The water flooding these became radioactive and will take many years to remove
  • Although the radiation leak was only about 30% that of Chernobyl and radiation levels in the air low, one third of a million people were evacuated as the plant was sited in a densely populated area
  • Later reports showed the accident was caused by human error – it was not built to withstand a tsunami even though it was close to the sea in an earthquake zone. The plant is still not secured
  • After the disaster, there were anti-nuclear demonstrations in other countries and Germany announced it was closing older reactors and phasing out nuclear power generation. France, Belgium, Switzerland all had public votes to reduce or stop nuclear power plants. In other countries, plans for nuclear plants were abandoned or reduced
  • System
    An organised collection of interdependent parts that perform a function and which are connected through the transfer of energy and/or matter
  • Systems approach
    A way of visualising a complex set of interaction which may be ecological or societal
  • System
    Composed of storages and flows
