Hope for the oceans in a time of COVID-19

April 14, 2020 — The following was released by the Environmental Defense Fund:

The global COVID-19 pandemic gives us all pause about what the future holds. Our focus and attention are on all those hurt by this terrible disease. But for many of us, this is also a time of deep reflection about society and the world we’ll inhabit when this scourge is over. So for me, it’s also a moment to reflect on the prospects for the ocean, one of the planet’s fundamental life-support systems — making it vital to human health and well-being.

A just-released article in Nature, by Professor Carlos Duarte of King Abdullah University of Science and Technology in Saudi Arabia and colleagues, argues that the global ocean can once again return to abundance, rebounding from overfishing and pollution by 2050, if humanity puts its shoulder to the wheel and redoubles efforts across all types of threats. We emphatically agree.

Here, we dive into what such lofty ambitions might require, through one of the key lenses that Duarte and company identify: sustainable fishing.

First, peer-reviewed research shows very clearly that sustainable fisheries management works.  That should come as no surprise. Our own work with University of California, Santa Barbara and others (Costello et al., 2016) modelling the world’s fisheries showed that the “upside” of informed and effective management rapidly outweighs the downside of unsustainable fishing (which would otherwise deplete more than 85% of fish populations). Our modelling shows that such management approaches would allow full rebuilding of most stocks (and total global fish abundance) in less than a decade — restoring fish as a valuable asset both for nature and human needs. This exciting finding was recently underscored by a deep and systemic analysis (Hilborn et al., 2020) showing that, in fact, when good management is put in place, fish and fisheries respond impressively.

Why the death of coral reefs could be devastating for millions of humans

November 10th, 2016 — Coral reefs around the globe already are facing unprecedented damage because of warmer and more acidic oceans. It’s hardly a problem affecting just the marine life that depends on them or deep-sea divers who visit them.

If carbon dioxide emissions continue to fuel the planet’s rising temperature, the widespread loss of coral reefs by 2050 could have devastating consequences for tens of millions of people, according to new research published Wednesday in the scientific journal PLOS.

 To better understand where those losses would hit hardest, an international group of researchers mapped places where people most need reefs for their livelihoods, particularly for fishing and tourism, as well as for shoreline protection. The researchers combined those maps with others showing where coral reefs are most under stress from warming seas and ocean acidification.

Countries in Southeast Asia such as Indonesia, Thailand and Philippines would bear the brunt of the damage, the scientists found. So would coastal communities in western Mexico and parts of Australia, Japan and Saudi Arabia. The problem would affect countries as massive as China and as small as the tiny island nation of Nauru in the South Pacific.
