Simple.
Just look at the statistics of shark related attacks and then deaths from these attacks, then compare that to car accidents and deaths from car accidents.
Which is more prevalent and more of a concern for the entire population?
Therefore, it is self explanatory where the time, money and energy should be spent.
Australia, as of Feb 2008, has had 103 total shark attacks, 38 of those fatalities and the last fatality in 2006. Stats from 1700 and 2008.
ANOTHER website says 650.... EVEN if 1000 attacks per year, and say 5 deaths per year...
ANOTHER "In the last 50 years, there have been only 60 human fatalities (1.2 per year) in Australian waters from shark attack. "

I know this is the States but...
6 420 000 car accidents in 2005 2 900 000 were injured 42 36 were killed 115 people die everyday in the US. One death every 13 minutes
NOW compare the relevance of each statistic, and tell me where logically and mathematically time, money and energy should be spent!?
