Sea Worms. The sea worms are a large and varied group of animals belonging to a group called annelida. They are segmented worms, and all bear at least some resemblance to the common earthworm. In the ocean, however, the worms have evolved many different appearances. One of the more interesting varieties is the tube worms. These animals form a hard-shelled tube that provides them protection.
Earthbag building is a low-tech solution to making foundations (or entire buildings) using basic materials and simple tools. Drawing on the age-old technique of rammed earth building, earthbag uses woven sack material to provide a ready-made, leave-in-place formwork for containing rammed earth mixtures.
Environmentalist, humanitarian, and engineer Nader Khalili developed the idea of Earthbag, Flexible Form Rammed Earth, Super Adobe about 50 years ago. Nader recognized it's potential when he saw that it was very versatile and functional by the way it withstood time and the elements for holding back floods and with it's use as bunkers from the war. He explored it's potential in order to submit it as a viable option for quality emergency housing to the United Nations.
