If you think you are powerless against overwhelming environmental problems, these five people will change your mind.

Environmentalist Sasin Chalermlarb, biking activist Saranarat Kanjanavanit, architect Yanyong Boonlong, organic rice farmer Lalana Sri-kram and cardiologist Rungsrit Kanjanavanit will share their work, which has inspired a large number of people to do their part to save the planet, at the “Do It Better” talk, on Oct 18 from 1pm to 6pm.

Organised by Salforest, a social enterprise which promotes sustainable development, the talk will be held at Wiwattanachai Hall of the Thai Summit Building, New Phetchaburi Road. It can be reached by MRT Phetchaburi station.

Sasin, secretary-general of the Seub Nakasathien Foundation, successfully mobilised mass protests against renewed efforts to build the Mae Wong Dam by walking from the dam site to Bangkok and using social media to garner support.

Yanyong designs new living spaces that improve the quality of life and strengthen community ties of those living in slums. He also designs canal-rail connectivity to help ease Bangkok’s traffic gridlock.

Saranarat, secretary-general of Greenworld Foundation, is an avid cyclist and a driving force for Bangkok’s “car-free” day.

Lalana founded the Raithong Organics Farm, which links organic farmers to urban consumers and promotes urban farming.

Dr Rungsrit, an avid birdwatcher and wildlife conservationist, believes health and the environment are closely related. He uses birdwatching activities and social media to promote environmental awareness.
