The article provided a balanced account of declines in species and populations caused by fisheries, habitat degradation and likely effects of climate change and suggested that losses will rapidly intensify, especially from habitat degradation, as human use of the ocean industrializes.

Finding ways to acknowledge problems without implying that they are universal and irreversible would give people a more realistic and actionable perspective. However, our thought processes evolved over hundreds of thousands of years and they are not likely to change quickly. Heightened attention to potential dangers helped our ancestors survive and will likely help us too.

The price of that wariness may be seeing the world as more threatening--and threatened--than it really is. If those responses breed despair and cynicism that prevent actions to improve conditions, emotions that once served us so well will create a self-fulfilling prophecy. The ocean and most of its inhabitants are reasonably resilient and will survive, and even thrive, if we manage our ocean interactions more effectively and sustainably. There is time to rectify most ocean problems if resolute actions are taken--but they must be taken soon to avoid long term calamities, including climate change caused by excessive emissions of carbon.

The ocean is not dying and it may have a little more patience with us than we credit, but we need to have a lot less patience with ourselves. Which article will you open?

Saint of the Day St. The reason that wreck fishing is one of the most popular forms of sea angling is that these places are avoided by bottom trawlers, giving them de facto protection. Where trawling occurs, congers are scarce. It was bottom trawling that led to decline.

Trawlers catch fish by dragging their nets over the seabed. It is not hard to imagine the damage this did to the great fields of invertebrates that lived on the bottom, including corals, sponges, seafans, sea nettles, oysters and hundreds of others. While big fish were the mainstay of net and hook-and-line fisheries from the middle ages to the early 19th century, they declined rapidly with the spread of trawling, especially when steam power was added in the s and 90s.

A recent analysis of catch records shows that the amount of fish caught by trawlers for every unit of power expended has declined 25 times from the s to the present. The simple reason is because there is less life in the sea. While this is certainly true now, and it will become increasingly problematic in future, the primary driver of decline to date is overfishing. Ask an EU official for the latest stock estimate of common skate, and you would get a puzzled look.

We no longer fish commercially for species such as common skate because there are hardly any left, so we no longer bother counting them and their disappearance goes unremarked. But fishing carried on long after the skates, halibut, wolf-fish, angel sharks, bluefin tuna, thresher sharks, porbeagle, sturgeon and wild salmon — the list is a long one — dwindled to irrelevance. What is not widely known among those outside the fishing industry is that managers deliberately aim to reduce stock sizes of the fish we eat. Cutting the amount of fish in a stock frees up resources for the others, so they grow faster.

This theory, developed in the midth century, says that maximum productivity is reached when you reduce a stock by half, a point called the maximum sustainable yield.

  6. Fishing at MSY was recently embedded in the reformed European fisheries policy, which should have been a good thing given that stocks have been so depleted. At these low levels though, we are on dangerous ground. When life is brought low, there are unwanted and unanticipated knock-on effects. Predators like tuna, sharks, porpoises and whales are not mere embellishments, nice to have but not critical if lost. They once regulated the abundance of their prey and weeded out diseased and parasite-laden creatures before populations became seriously affected.

    They were important in cycling nutrients through ocean ecosystems, shuttling them from the depths to the surface where sunshine and plants could turn them into the energy that feeds all life in the sea. Seabed life, those waving fields of invertebrates swept aside by trawls, — captured carbon and sequestered it into the sediments.
