Scarcity of the resources vital to economic development and growth hits the developing countries the hardest: not only do they need to export most of their resources in order to develop their economies and to import those resources they lack, but many developed countries are stockpiling fossil fuels and minerals in order to secure their own future needs, thus diminishing prospects of the developing countries being able to secure supplies adequate for their present requirements. The maldistribution of industrial power and technology, and of the wealth they produce, exacerbates the discriminatory international order, as does the mounting pollution of soil, water and air by the wealthy countries, which are rapidly poisoning and extinguishing plants and animals necessary to the survival of the entire world. Through its production and consumption lifestyle, the 20% of the world's population in the North accounts for more than 80% of the gases which are causing climate change and depletion of the ozone layer.
