Richest countries pollute, poorest countries suffer

Poorest countries suffer more than richest countries because of emissions of carbon, although they are less guilty. These emissions cause global warming and, in these countries, increase the risk of diseases like malaria and dengue, a severe fever of viral origin. The geographer Jonathan Patz (University of Wisconsin) quantified the problem: he compared CO2 emissions per capita with the increase of these diseases because of global warming. The result is merciless: Americans, for example, have an output of carbon dioxide six times above normal, but their risk is lower.
