What are some ways you can reduce the number of fishnets in the ocean?

Answer:

August 11, 2014 — Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t part of the EU and hold a strict discards ban, the waste was shocking.

When this news reached Dan Watson, a young British designer, it became the inspiration for SafetyNet, an ocean fishing net that allows certain fish to escape via lighted rings, offering more catch selectivity. The Scottish fishermen’s predicament, he believed, was driven by their lack of control. “There can be no villains, there can be no victims, there are just problems,” Watson says. “I started this project because I wanted to go some way towards solving that problem.”

Bycatch can result in overfishing, reduces the population of species that might already be endangered and, on the largest scale, interrupts food chains and damages whole ecosystems.

Watson joins a growing number of innovators designing more selective fishing gear to reduce bycatch — the unwanted fish, dolphins, whales and birds that get scooped up by longlines, gillnets and trawlers each year and then discarded. Globally, the amount of marine life that is wasted or unmanaged — which makes it potentially unsustainable — forms about 40 percent of the catch. “The way we catch now is to catch everything, decide what we want to keep, and discard the rest,” says Martin Hall, head of the bycatch program at the Inter-American Tropical Tuna Commission, which regulates tuna fishing in the eastern Pacific Ocean. Bycatch can result in overfishing, reduces the population of species that might already be endangered and, on the largest scale, interrupts food chains and damages whole ecosystems. It also amounts to an enormous waste of valuable fish protein.

To designers building better nets and lines, bycatch isn’t viewed as an inevitability, but as something we can phase out, piece by piece. It’s also seen as a battle that needs to be fought alongside fishermen, not against them.

Rethink the Game

Speaking from his trawler, the 45-foot Proud Mary, off the coast of Massachusetts, one such fisherman, Christopher Brown, says that over the years, fishermen have had to “rethink the game.” Brown operates a fishery that’s almost completely free of discards; is the board president of the Seafood Harvesters of America, an organization representing stewardship-minded fishermen; and has designed a squid net that reduces bycatch. The net contains an escape route at its base that exploits the bottom-dwelling behavior of unwanted flounder, encouraging them to flee the net through this gap. “We need to look at things entirely differently than we have in the last 30 years,” Brown says — and new gear is part of that equation. “It’s a matter of enlightened self-interest.”

Tundra and desert biomes have shallow soil profiles because weathering is limited by a lack of
nalin [4]
<span>Extreme temperature and bedrocks Tundra and desert both have shallow soil profiles because of the extreme temperatures and the bedrocks it has. In the case of tundra, it has extreme cold temperature and the soil were covered in ice in long periods of time. Because of this, the plants were unable to get water from the bedrocks resulting in plants dying. In the desert, however, it has extreme hot temperature making the plants unable to survuve due to lack of water in the environment and in the bedrocks. The plants that can only survive in this temperature are the plants that has the ability to store water in their system.</span>

Which of the following molecular movements is due to diffusion or osmosis? a) The sodium-potassium pump pumps three sodium ions
MrMuchimi

Answer:

The correct answer is  b) When a plant cell is placed in concentrated salt water, water moves out of the cell.

Explanation:

Osmosis is the movement of solvent molecules from an area of less concentration of solute to high concentration of solute to equalize the concentration of both the side of the cell.

So water will move outside the cell when any cell will be placed in a concentrated salt water because the concentration of solute is high in salt water and low inside the cell.

Therefore when a plant cell is placed in salt water the osmosis of water takes place from inside to outside the cell. So the right answer is b.
