o your bit to save the environment even if it is a tiny step, urges actress Priyanka Chopra who is working for a greener tomorrow as the brand ambassador of NDTV-Toyota's "Greenathon II" campaign.

"This is a fantastic initiative. I'm a part of the young generation who questions almost everything. But we need to understand that it takes little things for something to become big, " Priyanka told reporters here Tuesday.

"Youngsters often ask - 'What can we do?' But I believe it is only the simple things we can do that can bring about a change. Get involved in such initiatives, spend a weekend doing something good for the environment and you will feel happy... let's make the earth a better place, " she added.

The first edition of "Greenathon", a campaign initiated by The Energy and Resources Institute (TERI) in association with NDTV and Japanese auto giant Toyota, aimed to raise funds for the 'Light a Billion Lives' project. The aim was to take solar lanterns to rural communities.

The campaign ended up raising Rs.20 million and lit up 55 villages across India.
