Bangladesh is in the tropics and has a coastal location, making them vulnerable to tropical cyclones. 156 million people are in an area that's 60% the size of the UK, meaning they have a high population density. Due to climate change, river discharge has been increased due to melting in the Himalayas. 80% of the country is less than 10m above sea level which means it can easily flood. The widespread of the population - 31& of civilians live on <$2 a day.
