States who pollute majorly are responsible for the traumatic lives of refugees and must hence open their borders to allow their entry in a regulated manner. Environmental refugees are equally important in today's world and deserve a chance at life in the normal world, At the expense of the state.

If they have an airport, They are contributing to pollution. If they have livestock like cows, They are contributing to methane pollution. Not one single country can safely say that give off no pollution and that their people don't lite fires giving off carbon dioxide. Each country is responsible on some level,
