OECD published on Tuesday 13 March two books presenting the latest prospects concerning the socio-economic evolutions for the next four decades and their impacts on four important fields: climate change, biodiversity, water and environment pollution effects on health.
Costs of inaction could be enormous according to OECD. The growing energy demand will result in an increase of 50% in world's greenhouse gases and worsening air pollution. Such pollution could become by 2050 the first environmental cause for death in the world. China and India will be by far the most affected countries. The world water demand will increase of about 55%. 2.3 billion additional people will lack water.
