Besides enterprises, individuals also contribute a lot to bettering the environment. Afroz Shah is one of them. The Mumbai lawyer won the UN Champions of the Earth award last year. He is the man behind the world's largest beach clean-up campaign. He and his volunteers have removed millions of kilograms of garbage from a beach in the city over the past couple of years. Our correspondent Rebecca Bundhun reports from Mumbai.

A sea of litter washed up on Mumbai's Versova Beach. The scene was so distressing to one lawyer, Afroz Shah, and his 84-year-old neighbour, who has since passed away, that one day two years ago, the two men went to the beach to clear some of the trash themselves. This gathered momentum to turn into the world's largest beach clean up campaign. Afroz and an army of volunteers – from schoolchildren to Bollywood stars - have been going to the beach almost every weekend to pick up garbage.

AFROZ SHAH LAWYER AND ACTIVIST "It boiled down to the fact that we have to be part of the solution. I told myself that I'm not going to complain. We have littered. We humans are responsible for littering all this, and now we must take charge and do something about this."

The efforts of the volunteers, combined with some work by local authorities, have helped improve the cleanliness of the beach enormously.

 NILOFER KAZI LOCAL RESIDENT AND VOLUNTEER "I've been associated in beach cleaning with Afroz Shah like one year back, one and a half year back. I'm happy with him. I'm happy to clean the beach in my area. This is my beach."

Afroz has won a number awards for his work, and has even been praised by India's prime minister.

REBECCA BUNDHUN MUMBAI "Afroz and his volunteers have cleared a total of 9 million kilograms of waste from this beach to date. But it's a never ending task given the amount of garbage that washes up every day."

And the campaign has faced some choppy waters. Afroz recently briefly temporarily suspended the campaign because of factors including his volunteers facing verbal abuse. But he refused to give up so easily.

AFROZ SHAH LAWYER AND ACTIVIST "There's a prediction that by 2050 there will be more plastic in the ocean than fishes, by weight. That's scary. That's horribly scary for our planet."

Afroz hopes others around the world will gain inspiration to take action to help the environment. He explains he has made a lifelong commitment and he'll keep cleaning the beach for as long as he physically can. Rebecca Bundhun, CGTN, Mumbai.
