Increased CO2 in World’s Oceans Causes Fish to be Attracted to Predators

Human activity is not only causing increased carbon dioxide (CO2) emissions in our atmosphere, but our oceans are suffering as well. CO2 absorption causes the water to become more acidic, which in turn alters marine life’s natural instincts to avoid predation. Researchers fear the results will have “far-reaching consequences for the sustainability of fish populations”.

Does Climate Change Cause Crime?

Here’s the theory: climate change contributes to rising temperatures and dropping water levels, which in turn leads to lower catch volume and smaller fish, which pushes some Lake Naivasha fishermen in Nairobi’s Rift Valley to cast their nets into the world of crime. Naivasha police say that most of their recent arrests for kidnapping, rape, robbery, carjackings and other crimes have been of fishermen, up to ten a week. In addition, fishing has become so difficult that fishing “cartels” are forming, and some have been killed for fishing in a group’s regular territory.

Australia’s Integrated Marine Information System Makes a Splash

There is literally an ocean of information floating around out there about almost anything you can think of, but seldom is that information brought together in an integrated, meaningful and useful way- especially when there are multiple governmental and scientific groups involved. But a new high-technology marine information system in the waters off of South Australia is looking to condense puddles into a usable stream. The new system will record information about wind speed, ocean currents, water temperature and salinity and make it available on the Internet for anyone who needs it.

Oceans Without Fish in 40 Years?

Ok, “without fish” is a little bit of an overstatement, but a new report out by the United Nations Environment Program (UNEP) and leading economists warns us that if fishing policies don’t change, all commercial fisheries could collapse in the next 40 years, which is pretty dramatic. UN Under-Secretary General and UNEP Executive Director Achim Steiner has made it clear that we really are heading towards unprecedented disaster if policies aren’t changed:

“Fisheries across the world are being plundered, or exploited at unsustainable rates. It is a failure of management of what will prove to be monumental proportions unless addressed.”

UN: Dock 13 Million Fishing Boats to Save Global Stocks

Stark predictions lie ahead for the fishing industry if action is not taken immediately to preserve stock, according to the United Nations Environmental Programme (UNEP). Warning that “virtually all commercial fisheries will have collapsed by 2050 unless urgent action is taken”, scientists estimated 13 million boats need to stop fishing immediately to save global fish populations. Such drastic measures would shrink the world fleet to seven million vessels.
