I think the poster "Building back greener" should show the polluted earth recovering green again with people's efforts. I think individual efforts are the most important to prevent climate change, and I believe that individual small efforts can bring the Earth back green. Therefore, in order to bring the earth back to a green state, he added a picture of the efforts that individuals could make, such as watering plants and picking up trash, and thus showing the Earth changing blue. I think 'Building back greener' is very important to both me and my country. Especially in Korea, climate change is changing and decreasing the kinds of fish caught in the sea. Because of this problem, 'Building back greener' is important to my country and me.
