You are blaming everything on Americans...I do not know where you live but I have traveled quite a bit..and America has the cleanest beaches, cleanest cities, cleanest forest and national parts, cleanest highways, clean drinking water, and the cleanest air of most continents. At least America has regulations, a police force that tries to regulate, and people that do give a *hit...
My guess is that in this instance, there were no regulations, no police, no protection of the beach, no signs, no education about the importance of the nesting... time to make a change to this.
