  • Founding of IUCN

    Aims to encourage international cooperation and "nature based solutions", as well as focuses on the impact of human activities on nature. Works to ensure that human progress, economic development, and nature conservation take place together.
  • Minamata

    This disease was caused by the consumption of fish contaminated by methylmercury compound from a chemical plant. Measures against the environmental pollution and efforts to improve it have been made. Minamata showed people what happens when society gives priority to economic goals, and lacks proper attention to the environment.

  • Rachel Carson's "Silent Spring" Published

    This publication was the beginning of the modern environmentalist movement in America. It argued that pesticides were dangerous to humans, animals, and would disrupt ecosystems. This familiarized the public with how much harm mankind could inflict on nature.
  • The Clean Air Act

    This act distributed $95 million for the study and cleanup of air and water pollution. The act gives the federal government the authority to reduce interstate air pollution, regulate emissions standards for stationary pollution sources, and invest in technologies that will remove sulfur from coal and oil.
  • Santa Barbara oil spill

    The Santa Barbara oil well spilled over 200,000 gallons of oil into the ocean for 11 days straight. Due to the damage caused and pollution of the California coastline, the spill led to reforms in the energy industry. Soon after, Richard Nixon signed the National Environmental Policy Act, requiring environmental impact reports.
  • Fire on the Cuyahoga River

    The Cuyahoga River in Ohio became so polluted that it caught on fire. This fire led to water pollution control activities such as the Clean Water Act and the Great Lakes Water Agreement. It also led to the creation of the federal Environmental Protection Agency
  • Establishment of "Earth Day"

    This holiday is marked by the world as a day of action to change human behavior and create global, national and policy changes. This led to the creation of the U.S. Environmental Protection Agency and the Clean Air Act.
  • Gaia Hypothesis

    Model of the Earth where its living and nonliving parts are viewed as an interacting system that can be thought as a single organism. Where all living things have a regulatory effect on the earth’s environment.
  • Stockholm Conference

    This UN Conference on the Environment was the first world conference to make the environment a major issue. Through this, the Stockholm Declaration was adopted which placed environmental issues at the forefront of international concerns. A major result of this conference was the creation of the United Nations Environment Programme (UNEP).

  • Whaling (save the whale)

    Greenpeace launched the world’s first antiwhaling campaign from the docks of Vancouver. This ignited a global “Save The Whales” movement, and helped secure an international ban on commercial whaling.
  • Bhopal

    More than 40 tons of methyl isocyanate gas leaked from a pesticide plant, killing at least 3,800 people. This event led to more international standards for environmental safety, preventative strategies, and industrial disaster preparedness. It established the importance of integrating environmental strategies into all industrial development plans for India.
  • Antarctic ozone hole discovered

    In the ozone layer over Antarctica, researchers discovered a 7.3 million square mile hole. Within two years after this discovery, the U.S. and more than 100 other countries pledged to phase out the use of ozone depleting compounds known as chlorofluorocarbons (CFCs).
  • Chernobyle

    At a nuclear power station workers violated safety protocols and power surged inside the plant, and caused a chain reaction of explosions inside. The nuclear core itself was exposed, causing radioactive material to go into the atmosphere. Due to the damage this has caused the environment and humans, it has led to a global anti-nuclear movement.
  • 5 billion

  • Launch of IPCC

    The UN launched its Intergovernmental Panel on Climate Change to assess the developing science in climate change, and to provide up to date information to governments. These reports are used are used as a reference point in international climate negotiations, which helps countries agree to take action.
  • Exxon Valdez oil spill

    An Exxon oil tanker ran aground in Prince William Sound, Alaska, spilling 11 million gallons. This oil spill catalyzed public opinion about the environmental dangers of oil, and led to the enactment of the Oil Pollution Act.
  • The Rio Earth Summit

    This international conference by the UN established a set of principles for improving and protecting the environment adopted by 178 countries. It was the first time the issues of economy, climate, and international development were considered together.
  • Agenda 21

    The Rio Declaration on Environment and Development, and the Statement of principles for the Sustainable Management of Forests were adopted by more than 178 Governments at the United Nations Conference on Environment and Development (UNCED) held in Rio de Janeiro, Brazil. This led to the creation of the Commission on Sustainable Development (CSD).
  • Kyoto

    This led to committing industrialized countries and economies to limit and reduce greenhouse gases emissions. Under the protocol countries actual emissions have to be monitored and records are kept. This has led to emissions being reduced and GHG emissions at a steady level.
  • 6 billion

  • Documentary film "An Inconvenient Truth" released.

    This is a film that addresses myths and misconceptions about climate change, and that global warming is real. It helped people worldwide finally understand the reality of the climate crisis destroying Earth, and encouraged people to take climate action.
