Greenhouse gas emissions should be reduced by 50% by 2050 from the 1990 level, warns UN. It is urgent to reach international agreements that avoid irreversible damage, but saturation media in climate issues, which seems to be fashionable, can numb the social conscience. Reduce the effects of air pollution is one of the great challenges of humanity. The overexploitation of resources, changes in temperature and the progressive warming of the planet merman ecosystems and cause the rapid extinction of some species.

The World Health Organization (who) celebrated this year the health day under the slogan protect health from climate change.

Already perceived an increase in deaths from heat waves and diseases transmitted due to natural disasters. Some developing countries reduced the growth of their emissions during the past three decades. Its development policies include renewable energies to ensure the protection of the environment and to allow a clean breakthrough.
