The Impact of Epidemic Outbreak ..
Before the SARS epidemic was over, ..
A study published in Journal of Epidemiology and Community Health and originating from the San Francisco-based Pesticide Action Network claims that 20% of our food is contaminated with pesticides that have been banned for decades such as DDT, dieldrin and dioxin. Finding up to five chemicals in foods is routine and adults may ingest up to 90 times the limit for a group of chemicals known as persistent organic pollutants (POPs), that persist for years, can build up in the body's fatty tissues and have been banned since the 1970s. Foods possibly contaminated with POPs are, butter, cantaloupe, cucumbers, meat loaf, peanuts, popcorn, radishes, spinach, summer squash and winter squash. A meal consisting of 11 ingredients -- notably turkey, stuffing, gravy, potatoes, green beans, squash, pickles and pumpkin pie -- featured 38 "hits" of POPs. Three-quarters of conventionally and one-quarter of organically grown produce contain chemical residues. The World Health Organization agrees it is important to ratify the convention on POPs. However 20% of foods may contain low levels of these chemicals, there is no consensus that they are hazardous to humans.
The spread of awareness and its impact on epidemic …
To be studied are the ecological and economic risks of the rising global trade in wildlife; catastrophic biodiversity "tipping points," which complicate predictions; how biodiversity loss impacts rates of natural carbon sequestration and carbon cycling on land and in the ocean, the emergence of new human diseases from wildlife such as HIV/AIDS, SARS, Ebola, and H5N1 avian influenza.
