Horseshoe crab number are drastically declining. The relationship between horseshoe crabs, humans and many shore birds beautifully exemplifies how all living species in nature are interrelated for survival.

Thanks to the advanced medical sciences and improved food sources and nutrition, humans are steadily increasing in number and approaching 8 billion. This insurmountable number, not only creating an imbalance in the nature but also many logistic problems. How are we going to be able to feed, cloth, house, educate, employ, and protect them from the ravages of climate change without invading and destroying the living environment of other species, thereby causing their disappearance?
