Document Summary
Policy like to have a definitive answer before they establish something , what"s why it"s been difficult to make policies. Because we have well developed public health system. Why re-emergence or emergence of infectious disease (also a concern in developed world) Bacteria evolve faster than predicted, our travels also. In cold environment it doesn"t spread so much. Large scale anthropogenic changes and interaction with the natural environment. E. g. climate change, land use, altered ecosystem, densities, globalization(more open means for them to spread), use of medication (might be negative) May act synergistically to alter exposure to infectious diseases and natural disasters. Btu challenging to demonstrate direct connections between degraded environmental conditions and negative health outcomes. Bacteria are close to each other, but through the process of mitosis, mutations can occur. Evolution occur faster on bacteria level than human level. E. g. when you stop before the who cycle completes, the person is selecting the leftover bacteria.
