Martin Rosen is the director of the Trust for Public Land, the organization that is coordination the stat-wide tree plating effort. “Time is not neutral. We are so rapidly depleting th

20、e atmosphere, we are so rapidly changing the climate, that unless we start now the situation may well become irreversible.” Some movie stars were on hand for the tree planting ceremony. Actor Peter Cyote served as the master of ceremonies. “Unless the environmental movement comes into everybodys lif

21、e, in real simple activities, its not going to work. Planting a tree is real simple.
