Speaking on the occasion, the Prime Minister said people should take pride in the number of trees planted by them the same way they take pride in worldly possessions.
He said that living in harmony with nature is the only way to avoid a catastrophic situation on Mother Earth.
Pitching for taking steps to protect the earth, Modi said, "Our ancestors have done it for us and now it is our responsibility to preserve it for the future generations."
Union Minister for Environment and Forests, Prakash Javadekar, was present on the occasion.
