Technology destroy the art of communication

Native American creativity is boundless and sacred. Artistic expression has been a way to worship the gods. Art for art's sake is not part of the Indian psyche. Their artistic designs have beauty and care motivated by their love for nature.

Now, a study published in Proceedings of the National Academy of Sciences adds to the mounting evidence that our hunger for piscine protein is laying waste to parts of the planet we have never even seen, leading to lasting changes in the sea floor that prevent recovery.

Trawls are bulldozing millions of square miles of the sea floor every year. A new study in PNAS says that if such fishing is sustained, this is all that will be left.

New kinds of boats were designed that can drag larger and larger nets deeper and deeper into the watery depths of the deep sea.

Such engineering prowess was well rewarded—and so we began to empty our oceans, tonnes upon tonnes of fish at a time. Modern technology has mastered the art of trawling. Bottom trawlers literally drag nets—up to feet wide and 40 feet high—across the ocean floor, collecting everything from corals to top predators.

These nets weigh up to 1, pounds and can operate miles below the surface, in habitats few have ever seen. A fisherman separates the shrimp from the bycatch from a bottom trawl. In some areas, fifteen pounds of bycatch are discarded for every pound of seafood obtained by the trawls.

In addition, trawls literally scrape the sea floor bare, dragging or crushing whatever species lie in their path, including fragile and slow-growing sponges and corals.

Pusceddu and his colleagues compared sediments from heavily trawled areas an untrawled areas of the Mediterranean Sea, examining physical and chemical properties as well as the living organisms present in them. Not only are fish, corals, and invertebrates wiped from an area with each sweep, the very nature of the sea floor is altered by chronic trawling.

Since upwards of 98 percent of all marine species live on or immediately above the sea floor, such dramatic changes in sediment biodiversity and chemistry are bound to ripple outward. These data explain why deep sea communities affected by trawling take longer than expected to recoverif they can recover at all.

More than scientists and dozens of NGOs and fisheries organizations had signed a petition in support of the ban. A decade ago, more than 1, scientists from 69 countries called for a global stop to bottom trawling.
