One Person Can Make a Difference

Sixth grade science project leads to breakthrough research according to an article by Brittany Shammas of the Sun Sentinel. 12 year old Lauren Arrington's research for her science fair project showed that the highly invasive lionfish can survive water with a much lower salinity than scientists had previously thought. This means that young fish in brackish waters may also be at risk of predation by the voracious lionfish.

Called prescribed grazing, people in Athens will be able to rent the animals for up to 30 days to help rid their property of invasive plants. So which should you choose, a sheep or a goat?
