Biology & Environmental Systems and Societies

Dynamics of Environmental Perspectives

  • Environmental perspectives (and the beliefs they are built on) shift and change over time in all societies

  • Although many different factors can cause these changes in perspectives, they are often influenced by government or non-governmental organisations (NGOs) campaigns or through social and demographic changes

    • For example, in the 1970s (and as early as the 1950s), there was a significant rise in environmental awareness due to campaigns against pollution

    • Government initiatives like the Clean Air Act in the UK (1956) and the establishment of the Environmental Protection Agency (EPA) in the US (1970) played important roles in highlighting pollution issues

    • NGOs like Greenpeace (1971) and Friends of the Earth (1969) also spearheaded campaigns, raising public awareness about the detrimental effects of pollution on health and the environment

Interpretation of behaviour-time graphs

  • Behaviour-time graphs illustrate how specific behaviours change over time

    • For example, a behaviour-time graph tracking smoking rates might show a decline over decades due to anti-smoking campaigns and general increased health awareness

      • The "Stoptober" campaign in the UK encourages smokers to quit during October, resulting in noticeable dips in smoking rates during those periods

  • Other examples of using behaviour-time graphs include:

    • Littering tendencies

    • Water usage

    • Recycling rates

    • Use of renewable energy sources

    • Use of public transport

    • Consumption of meat

    • Shifts from traditional indigenous lifestyles to modern ones

      • For example, Indigenous groups are increasingly adopting Western clothing and technologies due to globalisation

      • This transition can be seen in long-term studies that show changes in clothing styles, housing structures, personal belongings and food consumption patterns over time

Exam Tip

You should familiarise yourself with interpreting behaviour-time graphs to identify trends and perspective shifts over time. Pay attention to the axes, labels, and units to understand the scale and significance of the changes shown.

The Development of the Environmental Movement

  • The environmental movement is the term used to describe humanity’s increasing awareness of the damage we are causing to the environment and the importance of conserving the environmental health of our planet

  • The movement includes a diverse range of individuals, organisations and initiatives united by a common goal: to address urgent environmental challenges such as climate change, pollution, habitat destruction and species extinction

  • The movement promotes sustainable development, responsible resource management, conservation of biodiversity and the transition to cleaner, renewable energy sources

    • This can be achieved by implementing changes in public policy and encouraging changes in our individual behaviours

    • Through education, advocacy, activism and policy-making, the environmental movement aims to create a more sustainable and resilient future for both humanity and the natural world

  • Various different factors, including people, books, films and historical events, have been key in the development of the environmental movement

  • These events and influences have come from many different areas, including:

    • Individuals and environmental activists

    • Literature

    • Media

    • Major environmental disasters

    • International conferences and agreements

    • New technologies

    • Scientific discoveries

Description

Effect on Environmental Movement

Minamata disease in Minamata, Japan

1956

Chemical factories released toxic methyl mercury into waste water— mercury accumulation in fish and shellfish caused mercury poisoning in local people, with severe symptoms (neurological disorders, paralysis, death, or birth defects in newborns)

Raised awareness of the risks of industrialisation and the need for environmental regulations and checks to be imposed on industries
