Green Ukraine is an idea that some people have to make Ukraine more environmentally friendly, like how you try to make your room cleaner and nicer. People want to protect the Earth and keep it healthy for the animals, plants, and people who live on it.
To make Ukraine "greener," people might plant more trees and plants, use less energy from things like cars and factories, and try to make less trash that can hurt the environment. They might also try to keep the air and water clean, so that people can breathe and drink without getting sick.
If Ukraine becomes greener, it could help protect the Earth and maybe even make people's lives better and healthier!
