The most cause of Climate Change is human activity, caused by fossil fuels which produce carbon dioxide and other gasses.
The Western developed countries move to undeveloped countries to get resources to develop their countries.
They started with what they call Industrial Revolution which includes mining and agriculture there by causing land degradation.
The consequences of these activities, destroy the forests of the poor countries, causing Climate Change and leaving the people more poorer than they were before there by causing them to emigrate.
The Western Countries are going to see more and more migrants coming to their countries, and should be prepared to accept them, treat them with dignity, respect and give them fair justice as human beings.
So we say :
No more rejection of migrants,
No more destitution of migrants,
No more unfair treatment of migrants,
Because we are all human beings.
