Migration by humans has been a fact of life throughout their evolution. Homo sapiens emerged from Africa. Migration has been an essential mechanism for survival in the harsh climate and erratic agricultural conditions of the Sahara and Sahel regions for as long as people have lived there. To feed oneself, to provide for ones family , men and women will always seek other lands, and while the grass is still literally greener on the other side then men and women will endeavour to reach it. Only when it is possible to maintain an adequate living standard at home, will men and women stay at home. That is something Capitalism will never be able to offer many people throughout Africa.
Now a series of climate crises is forcing people to migrate, leave their homes and occupation. Climate change threatens to cause one of the biggest refugee crises of all time
Poverty, failing ecosystems, vulnerability to natural hazards and gradual environmental changes have always been linked to migration. The effects of warming and drying in some regions will reduce agricultural potential and undermine the provision of clean water and availability of fertile soil. The increase in extreme weather events such as heavy rains and resulting flash or river floods in tropical regions will affect even more people and generate mass displacement. A sea-level rise will permanently destroy extensive and highly productive low-lying coastal areas that are home to millions of people who will have to relocate permanently. Its main impacts are escalating humanitarian crises, rapid urbanisation and associated slum growth, and stalled development.
World socialism is a vision of the 'one world' principle - we have one world and that is to be shared between us all. A world of common ownership with free movement for all. The underlying problem to be eliminated is not migration but capitalism. In a socialist society humanity will for the first time be truly free and living according to natural principles, it will consciously direct its own development. Mankind will act consciously and according to a plan and to the whims of the market economy. With socialism overpopulation will not be an issue. The solution to the population “problem” is to overthrow capitalism for if production is geared to the needs of the people and not to filling the coffers of a few capitalists and their corporations there will be no population problem. It is not people who are “polluting” the world with their numbers but Big Business in search for profits
