Thailand
In previous years, Thailand earned the title of one of the biggest marine plastic polluters in the world. Citizens tended to dump trash into the ocean, and as a result, polluted the ocean and the beaches when trash washed up on shore.

Fortunately, this has gotten better over the years despite the negative record. Government initiatives, including reducing single-use plastic bags and containers have helped improve the problem drastically, even though it remains one of the most polluted areas in the world (The Thaiger).
