A new invasive snail has been observed near Miami (Florida) in August of 2020. If established, the snail can be problematic in nursery, greenhouse, fruit and vegetable production. Recognition is vital - if you see this snail, please report to state regulatory agencies right away (i.e. Texas Department of Agriculture). We also talk about the practical challenges with growing plants on Mars; something we're all going to encounter in the next 5 years or so... probably.
