What is Human Impact on the Environment?
Human activities are having a significant negative impact on the environment at a local, regional, and global level. Pollution of water, air, and land, along with deforestation and the burning of fossil fuels, is leading to a loss of biodiversity and contributing to climate change. Understanding these impacts is crucial for developing sustainable solutions.
Board notes: Covered by all major boards (AQA, Edexcel, OCR). The causes and effects of global warming, acid rain, and water pollution are key areas.
Step-by-step explanationWorked examples
Worked example
When fossil fuels like coal and oil are burned in power stations and cars, they release carbon dioxide, a greenhouse gas. This gas accumulates in the atmosphere, trapping more of the sun's heat and causing the average global temperature to rise. This leads to climate change, causing more extreme weather events and rising sea levels.

Common mistakes
- 1Confusing the greenhouse effect with global warming. The greenhouse effect is a natural and essential process where certain gases trap heat to keep the Earth warm. Global warming is the enhancement of this effect due to human activities releasing excess greenhouse gases.
- 2Thinking that pollution only comes from big factories. Everyday activities, like using cars, throwing away plastic, and overusing fertilisers in gardens, all contribute to pollution.
- 3Underestimating the consequences of deforestation. Removing forests not only destroys habitats and reduces biodiversity but also contributes to climate change, as there are fewer trees to absorb CO2, and burning forests releases vast amounts of stored carbon.

Frequently asked questions
What is acid rain?
Acid rain is caused by sulfur dioxide and nitrogen oxides, released from burning fossil fuels, dissolving in rainwater. It can damage buildings, kill trees, and make lakes and rivers too acidic for aquatic life to survive.
What is eutrophication?
Eutrophication is when fertilisers from farmland are washed into rivers and lakes. The excess nutrients cause a rapid growth of algae (an algal bloom), which then die and are decomposed by bacteria. The bacteria use up the oxygen in the water, killing fish and other organisms.
