Ecological productivity ( Health )

Climate change currently contributes to the burden of disease and premature deaths. Economic development will affect how effective adaptation to climate change will be. According to the IPCC report, it is likely that:
climate change will bring some benefits, such as reduced cold deaths.
the balance of positive and negative health impacts will vary from one location to another.
adverse health impacts will be greatest in low-income countries.
the negative health impacts of climate change will outweigh the benefits, especially in developing countries. Some examples of negative health impacts include increased malnutrition, increased deaths, disease and injury due to heat waves, floods, storms, fires and droughts, and increased frequency of cardio-respiratory diseases. According to a 2009 study by UCL academics, climate change and global warming pose the biggest threat to human health in the 21st century.
