Welcome Green Monsters! We're your online guide to making conscious choices that help people, animals and the planet.

There seems to be something about fish, crustaceans, and other types of animals collectively known as seafood that makes them hard for people to sympathize with. Maybe it’s because they lack the “cute factor” that some see in other food animals like cows, pigs, and ducks, or maybe it’s because people think they have no brains or no feelings, which, if you’re wondering, many scientific studies debunk.

But, regardless of your opinion of fish and their feelings, if you eat seafood, you’re contributing to the destruction of our oceans. As the demand for seafood continues, the fishing industry evolves, developing methods and equipment that catch more fish, more quickly, which unfortunately, wreaks havoc on the oceans.

When you purchase seafood, you’re directly supporting these practices, whether you agree with them or not. Is this something you really need to worry about? Yes! Because if the oceans die, every single life form on Earth will feel the devastating effects. Here’s how the seafood industry is killing our oceans:


Many people would shudder at the idea of eating a dolphin or a turtle, yet millions of dolphins, turtles, whales, sharks, seals, rays, birds, and other marine species are killed each year because they become tangled in equipment designed to catch other species and are unable to escape.

They are the inevitable by-product of the fishing industry, known as by-catch, and their useless deaths are throwing off the ocean’s food chains and ecosystems. Estimates put the amount of by-catch in the United States alone, to be between 17 – 22 percent of total catch, or 2 billion pounds every year. By-catch is a factor in the dwindling numbers of important predatory species and even contributes to the deaths of endangered species.

Another cause of unintended marine life death as a result of the industry comes from what’s known as ghost fishing, which occurs when nets, traps, and fishing lines fall off of or are left behind by fishing vessels. These pieces of equipment remain in the seas and continue to catch sea life, usually resulting in a slow death for their captives.

Species Depletion

Overfishing is one of the biggest threats to our planet. Entire species have been nearly obliterated by the demand for seafood, with experts estimating that nearly 80 percent of the world’s fish stocks have been fully exploited or are in decline and that 90 percent of the ocean’s large predatory fish have been wiped out. If current trends continue, the Earth’s food fisheries are likely to collapse entirely by the year 2050. These drastic depletions are causing devastating effects to the ocean’s delicate food chains and ecosystems.

Reef & Habitat Destruction

A fishing technique known as bottom trawling operates by launching huge nets from boats, which drag along the bottom of the ocean to collect their desired catch. These heavy nets consume everything in their path, resulting in a high yield of by-catch and they cause permanent damage to the fragile structures on the ocean’s floor.

Dynamite and cyanide fishing also destroy reefs and cause instability in the populations of species that call the reefs their home. Once a reef is damaged, it may take many years to regenerate, meaning an entire reef ecosystem can be destroyed in a matter of seconds with one pass of a trawler or a dynamite blast.

What You Can Do

So, the next time you go out to eat, please try to remember some of the facts presented here and consider ordering the veggie roll instead of the tuna roll.

Like most industries, the seafood industry relies on supply-and-demand for its survival. And, contrary to popular belief, “sustainable seafood” may not be any better. The only way to help put an end to the death of our oceans is to stop supporting it with your dollars, altogether.

Check out these awesome vegan seafood recipes and spend your money on plant-based foods, instead, and keep our seas healthy and alive for future generations.

From a Tourist Ranch to a Spacious Sanctuary: Ben the Bear Celebrates Two Years of Freedom!

Living on a 12 by 22 foot chain is no life at all for a black bear. In the wild, these astounding creatures can be up to seven feet tall and weigh up to 800 pounds. The black bear is incredibly adaptable and can be found in 40 of the 50 states in the U.S. But, despite their versatility, black bears should never be found in a concrete enclosure, chained down as a tourist attraction. This, sadly, was the life of Ben the bear who lived for six years at Jambbas Ranch Tours, a private ranch attraction in North Carolina. All alone in his paltry cement prison, Ben's only form of interaction can in the shape of tourists outfitted with cameras and a wallet full of cash. His caretakers fed him dog food and for entertainment, Ben was given a bowling ball and a few sad stumps of wood. After years of the monotony, Ben began to exhibit stereotypic behavior, pacing back and forth in his tiny enclosure. Pacing and other pointless, repetitive behaviors are symptoms of zoochosis, the form of mental illness that animals kept in captivity develop overtime in response to the stress of being held indefinitely. Walking back and forth on the hard concrete caused serious damage to the bear's footpads and it was clear that this was hardly a proper environment for a wild bear. Thankfully, some compassionate visitors alerted PETA and the Animal Legal Defense Fund to Ben's suffering and soon these two organizations filed a suit for his release. All evidence pointed to the conclusion that Ben was not being properly cared for and he was released to Performing Animal Welfare Society's (PAWS) ARK Sanctuary in California. Ben the BearPETA First Steps to Freedom With the help of FedEx (yes that FedEx) Ben and his new team of caretakers were on their way from North Carolina to California. The flight crew dubbed the plane "Bear Force One" for the epic journey. PETA writes that when Ben arrived at the sanctuary, it was likely the first time his paws had ever felt grass. Probably a great comfort after years of hard concrete. Within minutes, Ben was running through his new, spacious, 1.5-acre playground, going for a dip in the pool and exploring to his hearts content. Check out this video of Ben's first day at the sanctuary! It's amazing to see how quickly he adapts to his natural environment after six long years of living in a concrete prison cell. Quite the testament to the resiliency of animals. Ben's habitat is part of theBob Barker Bear Habitat, which was specifically designed for bears. The habitat includes trees, grass, natural vegetation and a large pool, much more suited to the needs of an adult black bear. Ben was given proper food for the first time and allowed to interact with the sanctuary's other black bears, Sampson and Cinnamon. Ben the Bear Ben spent his first week at the sanctuary foraging for food and learning what it means to be a wild bear again. Ben the BearPAWS According to PAWS, the USDA suspended Jambbas Ranch Tour's exhibitors license in January of 2014. The license cannot be restored until the facility is in full compliance of the Animal Welfare Act's regulations. We can't really say that we hope this happens any time soon ... Ben the BearPAWS Following the suspension of Jambbas' license, Ben celebrated two happy years at ARK sanctuary! Although Ben's story has a happy ending, he is a constant reminder of the suffering that many other bears are currently being forced to endure for the sake of human entertainment. Ben the BearPAWS Every bear should get to experience the SWEET taste of freedom! Ben the Bear What You Can Do For Other Bears Tourist attractions that feature live animals are rarely focused on anything other than profit. Although some attractions boast their dedication to conservation, and claim their profits go towards helping other, non-captive species, it is important that you do all your research before buying a ticket. Are the animals kept on chains that greatly limit their movement? Are they being fed a proper diet? Were these animals captured from the wild? Just like a zoo or a circus, roadside tourist attractions perpetuate the idea that animals are here for our entertainment, and wrongly send the message that animals "enjoy" performing for an audience. When you understand the basic needs and behaviors of wild animals, it becomes readily apparent that living on a chain in a small enclosure without mental stimulation or companionship goes against anything natural. Unlike cats or dogs, wild animals have not evolved to live with humans and forcing them to do so is only to their detriment. Education is the first step in ending the abuse of animal tourist attractions. Share Ben's story with your friends and be sure to report any animal abuse or neglect you might encounter. Without the help of the kind people who reported Ben's sad condition to PETA and ALDF, he might not have been rescued. Remember, animals can't speak, so it is our duty to speak up for them!

I try to eat seafood only in the summer and not in the winter. Although I might have a little left over in the freezer that I might bring out after summer is over. This way if gives the fish a break most of the year. Sushi on a hot day is nice but too cold on a cold winter day.

This a load of false information. I don\'t know where you get your supposed "facts" from. The fisheries I work in are the best managed in the world. The industry implements all government regulations and exceeds these by a fair way to ensure our fisheries continue to be productive for future generations. Oh and by the way, the total area of our EEZ that we fish is 2%. How are we destroying the other 98%?
PS. I gather this will not get posted to the board.

Even when I was a meat-eater I never ate fish just out of principle because of over-fishing. The 'I'm a vegetarian but I eat fish' brigade really get my goat. Just don't eat anything with a face - simples. In my opinion, the revolution to save our planet starts with what we put on our plates.
