Bangkok threatened by flooding

Bangkok, once known for its extensive canal network, is now facing severe sinking issues due to land subsidence and rising tides. Experts predict massive flooding by 2020, potentially affecting up to 20 million people. The city's coastal erosion is exacerbated by global warming and excessive groundwater extraction for industrial use. Despite existing flood prevention systems, Bangkok's low elevation and subsiding land pose significant challenges. Urgent action is needed to build effective flood defenses, as time is running out to prevent the city from becoming submerged.
