RODRIGUEZ BERTHEAU, Andrea María et al. Technological development, environmental impact and health. Rev Cubana Hig Epidemiol [online]. 2011, vol.49, n.2, pp.308-319. ISSN 1561-3003.

The improvement of living conditions caused by technological development increased world population, energy expenditure, food production and consumer goods. Turn accelerated environmental pollution, deforestation, the rise of big cities and other phenomena that have become a problem for humanity. We intend to show the current problems between the technological development of its impact on the environment, human health and the possible ways of finding solutions. Pollution attacks the human health, water or air, due to reduced crop yields, also on the health of livestock and fisheries. It has released sufficient quantities of CO² and other greenhouse gases that have caused an excess mortality estimated at 70 000 deaths in Europe, aggravate cardiovascular and respiratory disease with 1.2 million deaths each year in urban areas. The levels of pollen and other allergens are higher which may cause allergic conditions like asthma, which affects about 300 million people. Natural disasters have more than tripled since the sixties, every year these disasters cause more than 60 000 deaths. The increasing variability of rainfall will affect the supply of fresh water and which will endanger the health, increase the risk of diarrheal diseases that kill 2.2 million people each year. It has doubled the frequency of extreme droughts and their average length of six, increasing famine. Is likely to prolong the seasons of major vector-borne diseases such as schistosomiasis, malaria and dengue. The summit in Copenhagen showed the chaos of the world's governments since no consensus was reached in 2010 was postponed signing a binding treaty. In 2010 at the Cancun conference established the «Green Fund» to help poorer countries cope with climate change and policy commitments but no binding agreement was reached. It is necessary to understand the urgency of the measures and the importance of the participation of all in the care of natural resources.
