What is Human Impact on the Natural Environment?

Humans have had a profound impact on the natural environment at all scales, from local pollution to global climate change. Key impacts include deforestation to clear land for agriculture and cities, pollution of air and water from industry and waste, and the over-exploitation of resources like fish and minerals. Understanding and managing these impacts is one of the greatest challenges facing humanity.

Board notes: This is a synoptic theme that runs through the entire GCSE Geography course for all boards (AQA, Edexcel, OCR). Students are expected to understand the complex interactions between human activity and the environment across a wide range of topics, from river management to urbanisation and climate change.

Worked example

Common mistakes

• 1Thinking that all human impact is negative. Humans can also have a positive impact on the environment, for example, through conservation projects, reforestation schemes, and the creation of nature reserves and national parks.
• 2Seeing the environment as separate from the economy. The environment and the economy are fundamentally linked. Environmental degradation can have huge economic costs (e.g., the collapse of a fishery), while a healthy environment provides essential resources and services that support the economy.
• 3Believing that environmental problems are someone else's responsibility. While governments and corporations have a huge role to play, the cumulative actions of individuals – our consumption patterns, travel choices, and how we dispose of waste – also have a significant environmental impact.

Frequently asked questions

• What is the ecological footprint?

  The ecological footprint is a measure of human demand on the Earth's ecosystems. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Currently, humanity's total ecological footprint exceeds the Earth's biocapacity, meaning we are living unsustainably.

• What is rewilding?

  Rewilding is a large-scale conservation effort aimed at restoring and protecting natural processes and core wilderness areas. This can involve reintroducing keystone species, like wolves or beavers, that can help to reshape the ecosystem and increase biodiversity.
