Planting trees, leaving rubbish

Today the community (not sure from the village or somewhere else) went out to do something good. Saving the planet is always good, and one way is planting trees. Unfortunately they (at least the ones planting legt from the Anouvong statue) couldn't get the whole picture about saving the environment. For example, plastic bags are NOT good for mother earth. Due to this lack of education (no NGO responsible?) they just left it next to the tree. May it grow well!
