Coumadin (generic warfarin) is a poison.  Yet there are millions of people worldwide who take it daily as a blood thinner.  Its other use is to kill rats.
Alcohol is a poison.  Millions of people drink it every day worldwide in thousands of alcoholic beverages and survive.

Predicting the imminent apocalypse every day loses its effect after a fairly short period of time.  

When it truly is not so imminent as to require overhead protection from the falling of the sky like this subject or that of global warming, for example, 'real world' problems of feeding one's family or  getting to work in a gas guzzling vehicle on time often outweigh concerns about say, the rising of sea level which only is currently affecting some island nation someplace in the Indian Ocean or of what trees may be harvested in 35-40  years.
