consider how they can protect our planet. Here are three reallife stories of
people who are doing their part to make the earth a better place.

throw away old newspapers and plastic waste, she decided to use her skills to reuse these materials. Zhang collected these old things from her neighbours
and brought them back to life by turning them into amazing art pieces.
Li Qi runs a local restaurant. He realised that food production affects the
environment. So, he made a change: his restaurant now serves only food from local farms. By doing this, Li supports local farmers and reduces the
pollution caused by trans-porting food from far away.
Miss Wang loves nature. She started a commu-nity garden where she plants
trees and flowers. This garden improves air quality and provides habitats for wildlife. Wang also invites children to her garden. She teaches them the
