Truly, the price of development can be quite steep: according to experts, the ever growing human population and increasing reliance on antibiotics are major reasons why difficult strains of diseases keep popping up all over the globe.

As stated in scientific journal Nature, the increased contact between wildlife and humans resulting from the rapid growth of human population "is a recipe for something crossing over." That something, they say, are new diseases.

Some of the deadly diseases that were caused by contact with wildlife - often prevalent in poorer countries - are HIV, which is believed to have started from primates, and SARs, which was traced back to bats. Chinese bats.

On the other hand, the rich nations are also suffering from new strains of illnesses resulting from the constant use of antibiotics. Other factors stemming from development are also to be blamed, according to these experts.

Biologist Peter Daszak made an example out of the common bacteria, E. coli, which now spreads faster than the usual thanks to raw vegetables which are now being produced in centralized facilities. “Disease can be a cost of development,” said Daszak.
