Turtle Power!

Yes, it isn't just in popular 1980's cartoons. It's in the more than 45,000 people who have already signed the petition to help protect sea turtles from bottom longline fishing in the Gulf of Mexico. With 6 out of 7 species of sea turtles listed as threatened or endangered, continuing protections for these animals is critical, starting with working to limit the number of deaths each year from irresponsible fishing practices. Snared on sharp hooks or in nets, sea turtles often drown. In incidents of snaring by longlines in 2006-07 the government estimates nearly 1000 turtles were snared, with up to an 80% fatality rate. So call that 800 a year. 800 doesn't seem like that high a number, but consider that we have no idea how many sea turtles there really are because we can only track females who come to shore to lay their eggs. Male and juvenile sea turtles will spend their entire lives at sea.
But wait! There's more!
Fatality rates for sea turtle hatchlings are staggeringly high, due to natural predators alone. Add to that all the trouble man makes for them, and repopulating the oceans becomes a truly daunting task. Sea turtles are constantly losing prime nesting beaches to development, and like the polar bears and their melting ice, sea turtles are faced with the problem of global warming raising water levels and putting much of their nesting habitat under water. Even if the beaches are left alone, nearby lighting from developments can confuse turtle hatchlings, causing them to flounder inland and be run over on roads, die of dehydration, or become prey to domestic cats and dogs.
What more can you do to help besides signing the petition and donating to sea turtle conservation? Defenders of Wildlife has a list for you.

GreenPeace protection against Japanese Whalers

Hooray for a wish come true. Since I first heard the news about the Japanese intending to kill humpback whales for 'scientific research' the Greenpeace organization has been on my mind.
Now Japan has backed off of the humpbacks...but still intend to kill other whales including Fin whales and Minke whales..you can read more about it on the Greenpeace website.
I sometimes think people find Greenpeace to be too 'in your face' about their protection of environment and endangered species, but sometimes it is the only approach that works. On game reserves and in national parks in Africa individual teams of Park Rangers are often given exclusive guardianship over a specific animal, be it an endangered rhinoceros or elephant, or perhaps a pride of lions in order to protect them, with force if necessary from the danger of poaching. And Japan's plans to continue to kill protected whale species IS poaching. There is no scientific OR commercial basis for Japan's continued whale hunts. The market for whale meat is virtually non-existent at this point. Already whaling in Iceland has given up the ghost, due to the unmarketability of whale meat.
So what can you do to help? Aside from making donations to conservation organizations like Greenpeace, World Wildlife Fund, and Defenders of Wildlife, I encourage you to write to the tourism bureau of nations like Japan who refuse to concede to environmental science and let them know that you would never consider spending your hard earned money on a vacation to their nation until all unnecessary 'scientific' whaling ceases, and you would discourage anyone else from visiting as well.

Stop Illegal Whaling

Finally, Care2 has come through where Defenders and other organizations have failed me.
I have been in a tizzy since hearing on the news at least a week ago about Japan planning to add Humpback Whales to its list of 'scientifically' harvested species. In this day and age I see no reason why whales must be slaughtered in order to study them...indeed, whales in particular are more easily studied when ALIVE, so that migration patterns and communication can be studied. Japan's harvesting for 'scientific study' is nothing more than commercial whaling in disguise.

From Defenders of Wildlife: "Whaling is one of the biggest threats to whales. By the middle of the 20th century, whaling had left many populations severely depleted. The International Whaling Commission introduced a moratorium which continues to this day. However, there are still some exceptions to this moratorium. This allows countries like Norway, Iceland and Japan and the aboriginal communities of Siberia, Alaska and northern Canada to continue their annual whale hunts. "
Since the international ban on whaling in 1986 more than 30,000 whales have been slaughtered. Japan has already overstepped its bounds in the hunting of commercial fishes, we cannot allow them to continue to expand their control over our marine mammals as well. Whales are an apex and keystone species of the marine ecosystem, and the health of our oceans depends upon, and is reflected in the health of our whales. Please do your part to help them now, but signing this petition today!
Stop Japan's Illegal Whaling!

Arrr, more squid!

The headline reads "Voracious Jumbo Squid invade California!"
What a load of codswallop.
Sure, the Humboldt Squid is usually found in warmer more southerly waters, but it's not as if this is some foreign creature. Living at depths of 600 to below 2000 feet (only surfacing to hunt) and not well researched because of it, Humboldt Squid can none the less be found in numbers in the Baja region of California/Mexico where they're heavily fished by Mexican fisherman. A recent documentary showed the devastating impact this heavy fishing has on the species. While always aggressive on the hunt, the Humboldt Squid is normally a cooperative hunter, hunting its natural prey of anything from krill to hake and anchovies in groups. But when squid are being hooked and hauled aboard left and right the opportunistic predators go into a frenzy, attacking and eating anything in sight...including researcher's camera equipment. There are documented reports of Humboldts attacking divers, and famed videographer Scott Cassell has even made himself a 'squid suit' designed to protect him against their razor sharp beaks and chitinous teeth ringed tentacle suckers. Humboldt Squid only live for an estimated maximum of 4 years (sometimes only 1), growing in that time to a documented 7 feet in length. Researchers conclude that this is the reason for their sometimes uber-aggressive behavior. With such a limited time span the Humboldt Squid has to do whatever it can to survive and progress. This is also the reason why the Humboldt Squid is so adaptable, and therefore a 'problem' to California fishermen.
But let us consider the facts, kids. Why are Humboldts moving north? Could it be the pressure from fishing in the Baja region and the coast of South America? Could it be that Humboldts natural food sources in their historic ranges (aside from other humboldts) has been damaged? Or (my bet) could it be that commercial fishing has so decimated stocks of fish, both predator and prey, that the Humboldts are now filling a gap that was never there before? While the Humboldts feed on anchovies and hake (normally prey of the tuna in this region) the fishermen would love to catch, their numbers increase more dramatically because their natural predators (tuna, swordfish, shark) have been fished into a steep decline.
Why is it that when Nature is out of balance we always try to blame Nature, when really we should be taking a closer look at ourselves?
Unfortunately I can't find any organizations directly dedicated to Squid Conversation, so today you'll just have to suffice with educating yourself!
