1. Human Impacts on the Environment

2. The Environment is the world around us It is where we live, where we go to school and work It everything we see and everything we touch

3. We only have one earth and we all have to share it If we want to live in a clean and beautiful world then we have to take care of it To protect our resources For future generations

4. Air Pollution Water Pollution Industrialisation Acid Rain Deforestation Global Warming

5. Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals Causes of air pollution: –Burning of fossil fuels –Car and vehicle emissions –Indoor activities such as using a dishwasher, washing machine and tumble dryer and playing a video games. These all rely on electricity and often fossil fuels are burned in generating electricity.

6. Oil Spills Gasoline Spills Acid Rain Waste and Litter Sewage

7. Population growth leads to industrialisation Burning of fossil fuels Non-renewable resources Pollution Increased CO² levels

8. The burning of fossil fuels releases sulphates and nitrates into the air Sulphates and nitrates mix with the water vapour in the air and form sulphuric and nitric acid which falls as acid rain

9. Lakes and ponds can become so acidic that no life can survive in them

10. Population growth leads to deforestation People cut down trees to build homes This leads to the loss of natural habitat. Leads to a loss of Oxygen producers and Carbon Dioxide eliminators

11. Humans have a major impact on the rate of global warming The burning of fossil fuels (coal, gas, oil) produces greenhouse gases (carbon dioxide, methane, nitrous oxide, water vapour) These greenhouse gases trap the heat and light from the sun in the earth’s atmosphere, increasing the temperature of the earth
