Books, newspapers, scrap paper, soft drink cans, plastic bottles, used batteries, etc. are converted into trees - a series of activities organized by the Youth Union at all levels in coordination with schools in the province to spread green lifestyles, raise awareness of environmental protection for students, especially about waste classification.

The model of exchanging trash for trees organized by localities and units is a small but meaningful activity. What participants bring is trash, but what they bring back is not simply trees or gifts, but more importantly, awareness of waste classification in the place where they live and awareness to protect it.
