Debris(noun) : 1. the remains of anything broken down or destroyed; ruins; rubble:the debris of buildings after an air raid; scattered remains of something destroyed. 2. Geology. an accumulation of loose fragments of rock, left by a melting glacier etc.. First something on not so regular context to us – i.e., in Marine – at sea.Marine debris applies to floating garbage such as bottles, cans, styrofoam, cruise ship waste, offshore oil and gas exploration and production facilities pollution, and fishing paraphernalia from professional and recreational boaters. Marine debris is also called litter or flotsam and jetsam. Objects that can constitute marine debris include used automobile tyres, detergent bottles, medical wastes, discarded fishing line and nets, soda cans, and bilge waste solids.In addition to being unsightly, it can pose a serious threat to marine life, boats, swimmers, divers, and others. For example, each year millions of seabirds, sea turtles, fish, and marine mammals become entangled in marine debris, or ingest plastics which they have mistaken for food. As many as 30,000 northern fur seals per year get caught in abandoned fishing nets and either drown or suffocate. Whales mistake plastic bags for squid, and birds may mistake plastic pellets for fish eggs. At other times, animals accidentally eat the plastic while feeding on natural food.The largest concentration of marine debris is the Great Pacific Garbage Patch. In Apr 2917 in Colombia, a lethal mix of gravity, water and dirt combined to create an “avalanche” that tore through a small Colombian city, killing more than 200.What happened in Mocoa is known as a “debris flow,” which came during an unusually wet season, topped off with a shorter period of intense rain, federal landslide scientist Jonathan Godt said. He said he reviewed images and video of the Mocoa disaster, noting the mountains surrounding the city.“That very heavy rainfall makes the soil like goo, makes it easy to flow. It just starts sliding down the hillside,” said Godt, coordinator of the U.S. Geological Survey’s landslide hazards program. “My guess is that it was moving very fast and would have been full of rock and boulders and pieces of buildings. For someone experiencing it, an avalanche would be a very accurate description.” Witnesses reporting hearing buildings shuddering and vibrating as the flow crashed through Mocoa. Scores remained missing since the deluge struck when many people were sleeping, washing away trees, vehicles, houses and everything in its path. Pictures posted to social media showed bridges wiped away, piles of debris in the town center and overturned vehicles tumbled amid tree limbs, rocks and fencing. Godt, who has created small-scale landslides in Oregon for research, said debris flows like this one can be more devastating than a flood because the water gives the flow speed and the debris gives it extra punch. He said the flow would have been loud: Think water rushing, boulders crashing and trees being torn apart.“Gravity is always working to drag the mountains down, and water changes the strength of the material,” he said. “A layperson's description of this as an avalanche of mud and rock would be absolutely accurate.”
