Contrast point source pollution and nonpoint source pollution.

The point source and nonpoint sources can be differentiated:

1. Source of origin: In point source pollution the pollutants are originated from a identifiable and single source whereas in nonpoint pollution, pollutants originate from different sources and they get mixed therefore, the source of origin cannot be identified.

2. Control and prevention: As, point source pollutants originate from a single source they can be track back at their origin sites and their synthesis can be prevented whereas nonpoint pollutants originate from different sources their synthesis cannot be prevented.

3. Dilution level: The point source pollutant originate from a single source therefore remains in the concentrated form near the source of origin whereas nonpoint source pollutants originate from different sources therefore remain in diluted form.  

answer: andy garner, a 17-year-old who decided to become a human guinea pig in 1965 and go without sleep for 11 days. by the second day his eyes had already stopped focusing, and he lost the ability to identify objects by touch. by day three he was moody and uncoordinated and by the end he had trouble with short term memory and had even started hallucinating.

and a rare genetic mutation called fatal familial insomnia, where people can’t sleep at all, gets progressively worse over months or years and leads to dementia and death.

a devoted soccer fan died after staying awake 48 hours to watch the world cup, she said. ‘while his untimely death was due to a stroke, studies show chronically sleeping fewer than six hours a night increases stroke risk by 4 1/2 times compared with those getting a consistent seven to eight hours.'
