Associated Cause

Due to recent cyclone Vardah, Chennai has lost significant part of its green cover. Ainthinai, CTC's green wing, is actively working with Forest Department and other NGOs in greening the city through tree plantations and maintenance drives throughout the year. Our volunteers planted 7000+ trees in the last 4 years in and around the city. We need your support to cover related expenses tools for planting, manure for saplings, including tree guards, irrigation, transportation, etc. Your help will go a long way in supporting the ongoing green momentum to make our city a greener and more beautiful place to live in.
