Introduction to Climate Change

Climate change is when the Earth’s temperature gets warmer because of certain gases in the atmosphere. These gases trap heat from the sun, making our planet hotter. This can lead to extreme weather, melting ice, and rising sea levels.

Causes of Climate Change

The main causes of climate change include:

  1. Burning Fossil Fuels: This happens when we use coal, oil, and gas for energy. Cars, factories, and power plants all burn these fuels.
  2. Deforestation: Cutting down trees means there are fewer plants to absorb carbon dioxide, a harmful gas.
  3. Agriculture: Farming produces gases like methane, especially from cows and rice fields.

How to Reduce the Causes of Climate Change

1. Use Renewable Energy

What is it? Renewable energy comes from sources that won’t run out, like the sun (solar), wind, and water (hydro).

Example: Using solar panels on rooftops can provide electricity without polluting the air.

2. Save Energy

What can you do? Simple actions like turning off lights when you leave a room or using energy-efficient bulbs can save energy.

Tip: Use less heating in winter by wearing warmer clothes indoors.

3. Plant Trees

Why is this important? Trees absorb carbon dioxide, helping to clean the air.

Trick: Start a tree-planting club at school or in your community!

4. Reduce, Reuse, Recycle

What does this mean? Reducing waste means using less, reusing items instead of throwing them away, and recycling materials like paper and plastic.

Example: Instead of buying a new water bottle, use a refillable one.

5. Use Public Transport or Walk

Why should you do this? Cars release a lot of carbon dioxide. Public transport, cycling, or walking can reduce this pollution.

Tip: Organise walking or cycling to school days with friends.

Conclusion

By understanding how our actions contribute to climate change, we can make small changes that add up. Each of us can help reduce the causes of climate change and protect our planet for future generations. Remember, every little action counts!
