Giant African land snails invading Cuba

Kennedy couldn’t manage it in 1961, but someone else has. According to the BBC, Giant African Land Snails have been spotted on Cuban soil, which is bad news for native molluscs in the island nation as well as numerous plants. As if that weren’t bad enough, they also pose a health risk to people. This is one invasion Cubans definitely want to stop in its tracks, and for once the CIA has absolutely nothing to do with it.These snails have a number of characteristics that make them a formidable problem in regions where they’ve been introduced, which includes parts of Asia, Central America, and the US. For starters, they’re big. Really big. Giant African Snails typically grow up to eight inches long, and they’ve been known to get even bigger. They lay hundreds of eggs every month, with a very high hatch rate, ensuring that once a few snails make land, they can quickly spread across a region and they’re extremely difficult to stop — in part because applying molluscicide would kill other species. Also introducing predators is also problematic because all of the snail’s natural predators would be more likely to pick on smaller, vulnerable native species.

Scalloped Hammerhead Sharks officially endangered, and that is not good news!

It’s not really the kind of "first" you want to be: The peculiar-looking but oddly beautiful scalloped hammerhead shark has just become the first shark species to be added to the US Endangered Species List. Sphyrna lewini, as they're known, are coastal to semi-oceanic sharks with a number of extremely vulnerable subpopulations. The move to classify them as endangered is in response to lobbying from several animal welfare groups who hoped to secure additional protections for these amazing creatures before it's too late.

Who is exposed to more pesticides, rural or urban dwellers?

Who has higher levels of pesticide exposure, New Yorkers or rural dwellers near commercial farms? The answer might surprise you: for at least two classes of pesticide, New Yorkers are actually more exposed, despite the fact that we associate pesticide use with the application of such chemicals to crops to protect them from destruction during growing and harvest season. Research on the subject has significant implications for pest management and environmental health. Where are all these pesticides in New York coming from, and what can we do about it?
