Many marine ecologists think that the biggest single threat to marine ecosystems today is overfishing. Our appetite for fish is exceeding the oceans’ ecological limits with devastating impacts on marine ecosystems. Scientists are warning that overfishing results in profound changes in our oceans, perhaps changing them forever. Not to mention our dinner plates, which in future may only feature fish and chips as a rare and expensive delicacy.
The fish don’t stand a chance
More often than not, the fishing industry is given access to fish stocks before the impact of their fishing can be assessed, and regulation of the fishing industry is, in any case, woefully inadequate.
The reality of modern fishing is that the industry is dominated by fishing vessels that far out-match nature’s ability to replenish fish. Giant ships using state-of-the-art fish-finding sonar can pinpoint schools of fish quickly and accurately. The ships are fitted out like giant floating factories - containing fish processing and packing plants, huge freezing systems, and powerful engines to drag enormous fishing gear through the ocean. Put simply: the fish don’t stand a chance.
Ocean life health check
Populations of top predators, a key indicator of ecosystem health, are disappearing at a frightening rate, and 90 percent of the large fish that many of us love to eat, such as tuna, swordfish, marlin, cod, halibut, skate, and flounder - have been fished out since large scale industrial fishing began in the 1950s. The depletion of these top predator species can cause a shift in entire oceans ecosystems where commercially valuable fish are replaced by smaller, plankton-feeding fish. This century may even see bumper crops of jellyfish replacing the fish consumed by humans.
These changes endanger the structure and functioning of marine ecosystems, and hence threaten the livelihoods of those dependent on the oceans, both now and in the future.
The over-exploitation and mismanagement of fisheries has already led to some spectacular fisheries collapses. The cod fishery off Newfoundland, Canada collapsed in 1992, leading to the loss of some 40,000 jobs in the industry. The cod stocks in the North Sea and Baltic Sea are now heading the same way and are close to complete collapse.
Instead of trying to find a long-term solution to these problems, the fishing industry’s eyes are turning towards the Pacific - but this is not the answer. Politicians continue to ignore the advice of scientists about how these fisheries should be managed and the need to fish these threatened species in a sustainable way.
Help save our oceans by being smart about what types of fish you eat and how often you consume them.Here is a great pocket guide that informs people what fish are sustainably fished and which to avoid. Just print it out, put it in your wallet and you’re good to go! I also recommend watching End of The Line. It’s a great documentary that portrays and discusses this issue very clearly. REMEMBER EVERY SMALL CHANGE MADE TO HELP THE PLANET COUNTS!
Or you know, just not eat fish at all.
The nesting season for sea turtles began in the U.S. on March 1
Leatherbacks are the first to lay eggs along Florida’s Atlantic coast, followed by loggerheads and green sea turtles, pictured here, later this spring. Merritt Island National Wildlife Refuge is one of several wildlife refuges where the endangered green sea turtle (pictured) is found:

ANIMALS IN NEED OF FOOD! PLEASE SHARE, OUR HOPE IS THAT OTHER SANCTUARIES WILL STEP UP AND HELP PROVIDE IMMEDIATE RELIEF.
Urgent plea from the Director of the Kharkiv Zoo in the Ukraine.
The animals are left to starve to death in Ukrainian zoo as their Government has cut off their funds to divert the money to the political unrest that is currently gripping the country.
The Director of the Zoo, Alexey Grigoriev, is making a public appeal to please get the word out and is asking for urgent help to save these animals. They are no longer getting donated food. The situation is quite desperate. Most zoos, during times of civil unrest in many countries, get de-funded as funds are usually diverted for military aid; many animals are usually put down. However, this zoo director is taking the compassionate step of publicly asking the global community for help for the animals.
We would like to ask if any sanctuaries can at all make any arrangements with the zoo, to please contact the zoo.
