Study Notes
Environmental Science
- Fossil fuels (coal, oil, and natural gas) are non-renewable resources that will eventually run out.
Causes of Global Warming
- The main cause of global warming is the increasing levels of greenhouse gases, particularly carbon dioxide, in the atmosphere, primarily due to human activities such as burning fossil fuels and deforestation.
Types of Pollution
- Point source pollution originates from a single, identifiable source, such as an oil spill from a tanker or a factory's waste pipe.
Ecosystem Functions
- Wetlands play a crucial role in an ecosystem as natural filters, improving water quality by trapping sediments, nutrients, and pollutants, and providing habitat for diverse plant and animal species.
