About one hundred volunteers go into a mangrove forest in the suburb of Bangkok to clean the trash on the World Clean Up Day. Within an hour's time, people have collected more than 1.6 tonnes of rubbish, mainly plastic products including water bottles and food wrappers. Part of the trash will be sent to the recycle centre. "It is so painful when I see this amount of trash," says volunteer Faiyaz Ahmed. IMAGES AND SOUNDBITES
