Appreciation
Pollution is a serious problem around the world, and much effort has been put into the fight against it. Do you think things will change significantly in the future Work in groups and describe what the world will be like 20 years from now.
Critical thinking
Sample answer:
I predict that the world will be much cleaner and greener in 20 years. First, cars running on traditional fuels will be replaced by those powered by new energies, such as electricity or solar energy. As a result, the effect of greenhouse gases on the climate will be significantly reduced. Second, almost all reading and writing will be done on computer and phone screens, so people will cut down fewer trees and use less paper. Third, new technologies will be invented to make sure that our daily activities do not have a negative impact on the environment.
Lucid waters and lush mountains are invaluable assets.
Homework
