New Delhi, Aug 11 - Do 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.
