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
Examiner Tips and Tricks
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
