1. Urbanisation and Land Use:
- Urbanisation: As cities grow, land that was once used for farming is now being used to build houses and roads.
- Less Agricultural Land: When there isn’t enough land for farming, people start cutting down forests to create more farmland.
- Forest Reduction: This leads to fewer trees and smaller forests, which is bad for the environment.
2. Energy for Building Materials: To make materials like brick, cement, and glass, a lot of energy is needed. This energy usually comes from burning natural fuels like coal, natural gas, and oil.
3. Problems with Natural Fuels:
- Coal, oil, and gas are non-renewable, which means once we use them, they’re gone forever.
- Burning these fuels causes air pollution, which is harmful to the environment.
- These fuels take millions of years to form, so we should use them carefully.
4. Using Renewable Energy: Solar (from the sun) and wind energy are renewable, which means they won’t run out and won’t cause pollution. We should use more of these clean energy sources to protect our planet.
5. Eco-Friendly Shelters: All living things need shelter, including humans and animals.
Eco-Friendly Homes: Just like animals build eco-friendly shelters, we should also build houses that are good for the environment and sustainable.
