Greenpeace activists hold a banner with a message "Protect Chao Phraya Now!" in inflatable canoes in Chao Phraya River in front of Wat Arun temple to conclude its "Toxic free Chao Phraya river tour". Four Greenpeace activists began its unique river journey from Nakhonsawan last 22 May 2009, to raise awareness on the issue of unprecedented pollution of Chao Praya River by relentless dumping of industrial effluents and domestic waste into the river.
The "Toxic Free Chao Phraya river tour" aimed to inspire all stakeholders on the river, government and industry, polluters and impacted communities to catalyse a collective effort to find solutions to save the Chao Phraya River.
