Hey girl, I’m from 50 years ago. I’ve been wondering, what will the future world look like? Is it full of technology? Have the environmental problems been solved? In my world, we have lots of environmental issues, such as global warming, and natural disasters …. If all of these problems still haven’t been solved, I feel so sorry about that. I tried my best to change this, everyone is trying to participate in individual action, and scientists are trying hard too.
