Overheating Oceans and Overfishing Has Caused Fish Populations to Significantly Decline, Study Finds

For more than a decade now, scientists have suspected that we could have fishless oceans by 2048. So it shouldn't come as a surprise that human-caused climate change has already caused our oceans to overheat and reduce the overall fish population. According to a new study, the world's fish population has depleted by 4.1 percent since 1930, primarily due to overheating oceans. Luckily, there are plenty of actions we as humans can take to prevent a fishless ocean from actually happening.

The study, titled "Impacts of historical warming on marine fisheries production," was published in the journal Science this week, and authored by several universities and fishery science centers. For the report, the authors studied the "maximum sustainable yield" of 235 different temperature-dependent populations of 124 fish species in 38 ecoregions, from 1930 to 2010.
