Climate Change And Global Fisheries

April 12, 2019 By EarthWise Leave a Comment

A Rutgers University-led study published in the journal Science has shown that climate change has taken a toll on many of the world’s fisheries and that over fishing has magnified the problem.

Seafood has become an increasingly important source of nourishment as the global population grows, especially in coastal, developing countries where it provides as much as half of the animal protein eaten.  More than 50 million people worldwide work in the fisheries industry or subsist on fisheries.

Scientists at Rutgers and the National Oceanic and Atmospheric Administration studied the impact of ocean warming on 235 populations of 124 species in 38 ecological regions around the world.  Species included fish, crustaceans such as shrimp, and mollusks such as scallops.  They combined data on fisheries with ocean temperature maps to estimate temperature-driven changes in the sustainable catch over 8 decades.  The data covered about one-third of the global catch.

According to the study, ocean warming has led to an estimated 4.1% drop in sustainable catches, on average around the world, for many species of fish and shellfish from 1930 to 2010.  In five regions that include the East China Sea and the North Sea, the estimated decline was 15 to 35%.

The researchers recommend that fisheries managers eliminate over fishing, rebuild fisheries, and account for climate change in fisheries management decisions.  Over fishing provides a one-two punch to fisheries facing warming waters.   It not only makes fisheries more vulnerable to ocean warming but continued warming will also hinder efforts to rebuild over fished populations.

Changes in diet have often been proposed as a way to reduce overall greenhouse gas emissions.  However, there has not been much research about the affordability and feasibility of such changes.

Livestock And Antibiotics

According to the FDA, approximately three-quarters of all antibiotics used in the U.S. are fed to livestock for non-therapeutic purposes.  This routine administration of antibiotics promotes the development of antibiotic-resistant bacteria, which can spread to animals and humans.   And as antibiotic-resistant bacteria spreads, medicines used to treat human diseases can become less effective. Antibiotic resistant infections kill 90,000 Americans each year.

Many of us crave the scent and taste of grilled meat.  Even staunch vegetarians seek out imitation meat products that simulate the look and flavor of animal protein.
