The extent to which global demand for seafood is outpacing the sustainable yield of fisheries can be seen in shrinking fish stocks, declining catches and collapsing fisheries, according to the Earth Policy Institute.
Given these alarming trends, here are some need-to-know facts compiled by Earth Policy Institute showing the state of fisheries and people's growing reliance on farmed fish:
More than 80 percent of the world’s fisheries are either considered fully exploited, with no room for safely increasing the catch, or they are already overfished and in need of rebuilding.
Small forage fish account for more than half the food supply in 36 countries, including the Maldives, the Philippines and Ghana.
"It’s not just the well-known predatory fish like the endangered bluefin tuna that need a break. Scientists recommend catch reductions of roughly 50 percent for many forage fish—small plankton-eaters such as sardines, anchovies, and herring that are staples for larger fish and other predators," said Earth Policy Institute Research Associate J. Matthew Roney.
Farmed Fish Production
Wild fish play a large role in the production of meat, milk, eggs and farmed fish. Some 6 million tons of fishmeal and 1 million tons of fish oil are produced each year. Nearly all of the fishmeal is fed to farmed fish, pigs and poultry, and 74 percent of fish oil goes to fish farms.
People will likely eat more fish from farms than from the wild in 2014, a historical milestone. As the world’s oceans are fished to their limits, any increase in world fish consumption will come from farms.
Fish farming output is expected to increase 33 percent by 2021.
In 2012, world farmed fish production topped beef production for the first time ever.
China accounts for 60 percent of world farmed fish production.
Scale Back and Rebuild
Some aquacultural producers are scaling back. Between 1995 and 2007, the fishmeal content in shrimp feed dropped from 28 percent to 18 percent. The drop was even more dramatic for salmon, from 45 percent to 24 percent.
Well-managed marine reserves, where fishing is off-limits, will help protect biodiversity and rebuild fish stocks.
"The modern fishing industry that evolved to meet our ever-growing demand for fish and shellfish has created a situation where most fish stocks are maxed out or worse," said Roney. "It appears that there is little prospect for increasing the wild catch much further."
In fact, because widespread overfishing is already undermining oceanic food webs as well as the economic and food security of millions of people, it is clear that sharp catch reductions are needed for many fisheries. Leaving more fish in the ocean now to grow and breed is an investment that pays big dividends in future fisheries productivity."

Scientists have engineered a mutant enzyme that converts 90 percent of plastic bottles back to pristine starting materials that can then be used to produce new high-quality bottles in just hours. The discovery could revolutionize the recycling industry, which currently saves about 30 percent of PET plastics from landfills, reported Science Magazine.

Cabin fever is often associated with being cooped up on a rainy weekend or stuck inside during a winter blizzard.
In reality, though, it can actually occur anytime you feel isolated or disconnected from the outside world.
What is cabin fever?<p>In popular expressions, cabin fever is used to explain feeling bored or listless because you've been stuck inside for a few hours or days. But that's not the reality of the symptoms.</p><p>Instead, cabin fever is a series of negative emotions and distressing sensations people may face if they're isolated or feeling cut off from the world.</p><p>These feelings of isolation and loneliness are more likely in times of <a href="https://www.healthline.com/health-news/yes-covid-19-cases-are-rising-why-you-still-need-to-practice-social-distancing" target="_blank">social distancing</a>, self-quarantining during a <a href="https://www.healthline.com/health/what-is-a-pandemic" target="_blank">pandemic</a>, or sheltering in place because of severe weather.</p><p>Indeed, cabin fever can lead to a series of symptoms that can be difficult to manage without proper coping techniques.</p><p>Cabin fever isn't a recognized psychological disorder, but that doesn't mean the feelings aren't real. The distress is very real. It can make fulfilling the requirements of everyday life difficult.</p>
What are the symptoms?<p>Symptoms of cabin fever go far beyond feeling bored or "stuck" at home. They're rooted in an intense feeling of isolation and may include:</p><ul><li>restlessness</li><li>decreased motivation</li><li><a href="https://www.healthline.com/health/irritability" target="_blank">irritability</a></li><li>hopelessness</li><li><a href="https://www.healthline.com/health/unable-to-concentrate" target="_blank">difficulty concentrating</a></li><li><a href="https://www.healthline.com/health/irregular-sleep-wake-syndrome" target="_blank">irregular sleep patterns</a>, including sleepiness or sleeplessness</li><li>difficulty waking up</li><li><a href="https://www.healthline.com/health/lethargy" target="_blank">lethargy</a></li><li>distrust of people around you</li><li>lack of patience</li><li>persistent <a href="https://www.healthline.com/health/depression/depression-vs-sadness" target="_blank">sadness or depression<br></a></li></ul>
What can help you cope with cabin fever?<p>Because cabin fever isn't a recognized psychological condition, there's no standard "treatment." However, mental health professionals do recognize that the symptoms are very real.</p><p>The coping mechanism that works best for you will have a lot to do with your personal situation and the reason you're secluded in the first place.</p><p>Finding meaningful ways to engage your brain and occupy your time can help alleviate the distress and irritability that cabin fever brings.</p><p>The following ideas are a good place to start.</p>
When to get help<p>Cabin fever is often a fleeting feeling. You may feel irritable or frustrated for a few hours, but having a virtual chat with a friend or finding a task to distract your mind may help erase the frustrations you felt earlier.</p><p>Sometimes, however, the feelings may grow stronger, and no coping mechanisms may be able to successfully help you eliminate your feelings of isolation, sadness, or depression.</p><p>What's more, if your time indoors is prolonged by outside forces, like weather or extended shelter-in-place orders from your local government, feelings of <a href="https://www.healthline.com/health/anxiety" target="_blank">anxiety</a> and fear are valid.</p><p>In fact, anxiety may be at the root of some cabin fever symptoms. This may make symptoms worse.</p><p>If you feel that your symptoms are getting worse, consider reaching out to a mental health professional who can help you understand what you're experiencing. Together, you can identify ways to overcome the feelings and anxiety.</p><p>Of course, if you're in isolation or practicing social distancing, you'll need to look for alternative means for seeing a mental health expert.</p><p>Telehealth options may be available to connect you with your therapist if you already have one. If you don't, reach out to your doctor for recommendations about mental health specialists who can connect with you online.</p><p>If you don't want to talk to a therapist, <a href="https://www.healthline.com/health/depression/top-iphone-android-apps" target="_blank">smartphone apps for depression</a> may provide a complementary option for addressing your cabin fever symptoms.</p>
The bottom line<p>Isolation isn't a natural state for many people. We are, for the most part, social animals. We enjoy each other's company. That's what can make staying at home for extended periods of time difficult.</p><p>However, whether you're sheltering at home to avoid dangerous weather conditions or heeding the guidelines to help minimize the spread of a disease, staying at home is often an important thing we must do for ourselves and our communities.</p><p>If and when it's necessary, finding ways to engage your brain and occupy your time may help bat back cabin fever and the feelings of isolation and restlessness that often accompany it.</p>
