As a climate scientist, I strongly believe that planting more trees is crucial in our fight against climate change. Trees absorb carbon dioxide, a greenhouse gas, thereby reducing global warming impacts. Moreover, they enhance biodiversity and improve air quality. In short, reforestation is a vital step toward a sustainable future.

I believe high-income countries have a responsibility to lead the effort in tackling climate change because they have historically contributed the most to greenhouse gas emissions. They possess the technological and financial means to implement solutions effectively. By setting a strong example, they can help pave the way for global cooperation and support low- and middle-income nations in their sustainable development efforts.
