I ask the people to respect trees and attach great significance to the environment. The slogan, "Each Iranian Should Plant a Tree" --which is common among the people-- is a good slogan. The people should do their best to plant more trees on such days. Both the people and officials in particular should prevent the hands which try to destroy the environment. They should not allow our forests, grasslands and the environment in cities and suburban areas to be destroyed. If you do not act in a powerful and decisive way, the Alborz mountain range will turn into iron and cement all the way up to the peaks. That is to say, if you do not act decisively, some people will continue to take advantage of the situation. Of course, you mentioned that you are working on this. This is very good, but this should be visibly seen in practice so that people know fundamental measures are being adopted.
