3. What is the potential of nature-based solutions for climate change?

Nature-based solutions (NBS) harness the power of natural ecosystems to address climate change. This includes protecting and restoring forests, wetlands, and other ecosystems that act as carbon sinks. NBS also offer other benefits, such as improved biodiversity, water quality, and soil health. Examples include reforestation, afforestation (planting trees in areas where they didn’t previously exist), and restoring coastal ecosystems like mangroves and salt marshes. NBS are a cost-effective and sustainable way to mitigate and adapt to climate change.

4. How can individuals contribute to climate change solutions?

Individuals can make a significant impact by adopting more sustainable lifestyles. This includes:

• Reducing Energy Consumption: Using energy-efficient appliances, turning off lights when leaving a room, and reducing heating and cooling needs.
