The government is looking at ways to tackle Cambodia’s waste problem with a $1 charge on airline tickets touted to raise the cash. The move comes after footage emerged showing the capital’s canals remain clogged with rubbish a year after video of the pollution was shown around the world. More damning evidence of waste mishandling surfaced during the Water Festival, with a video of street-cleaning contractors sweeping rubbish into the Tonle Sap river. Now, the Environment Ministry wants to take $1 from every air ticket bought in Cambodia to go towards maintaining the environment. Environment Minister Say Samal said income generated will help to reduce the burden on the government.
