[Eco-pathologies: effect on public health and animal health]

This study emphasizes on pathologies which rates are increasing due to human activities that alter the environment such as industries, deforestación, etc.... This ecopathologies are different from those caused by occasional natural agents. On the contrary, the agents responsible for these pathologies include gases such as CO2, NO and SO, released to the atmosphere, metals such as mercury, cupper, plumb, cadmium and chrome, contaminating soil and water, and pathogens of protein nature, i.e. prions, extended through the utilisation of feed of animal origin in intensive farming.
