Study Notes
Greenhouse Gases
- The Earth produces greenhouse gases, which surround the planet and reflect heat back to Earth, making it warmer than space.
- Greenhouse gases are essential for the planet, but excessive production can lead to negative consequences.
Global Warming
- Global warming occurs when the climate becomes hotter due to an excess of greenhouse gases.
- Consequences of global warming include:
- Places becoming deserts (e.g., southern Europe)
- Plants failing to grow due to lack of water
- Animals becoming extinct due to lack of food
- These changes may not occur in our lifetime, but the world will change significantly in the next 50 years.
Carbon Footprint
- Carbon dioxide (CO2) is the main greenhouse gas contributing to global warming.
- Everyone produces CO2 through daily activities, such as:
- Using electricity
- Driving a car
- Taking the train
- Buying imported food
- A carbon footprint measures an individual's CO2 production in daily life.
- A large carbon footprint is detrimental to the environment.
Reducing Carbon Footprint
- To reduce carbon footprint, consider:
- Riding a bike or walking instead of driving
- Drinking tap water instead of bottled water
- Making small lifestyle changes can help mitigate the negative effects of global warming.
