If I had about 400 extra years of life, I could not possibly make a dent in the snail population off of just one little beach I frequent on the little island I call home. By walking along the shore at low-tide, you could easily kill thousands of them without even stopping to look at what it was crunching under your feet. Not to mention, the only laws I came across when researching this involved
endangered and
protected species, not invasive species of snails which come from another part of the world.
