Cos they caused global warming due to high carbon emissions. This has melted glaciers in mountainous regions and formed glacial lakes.
Unfortunately, the glacial lake is stoppered at its mouth by an unmelted ice wall, which will eventually break open as melting continues, to release a huge torrent of water and wash away the lives and properties of those living downstream.
Inhabitants in developed countries responsible for high carbon emissions better donate some funds to examine all the glaciers in the world, or else reduce the rate of CO2 emissions significantly if they want to maintain clean conscience and karma in the present world.
