Millions of Jellyfish Invade Nuclear Reactors

oxide7 writes "A nuclear reactor in Japan was forced to shut down due to infiltration of enormous swarms of jellyfish near the power plant. A similar incident was also reported recently in Israel, when millions of jellyfish clogged the sea-water cooling system of a power plant."

This is just further evidence, but by shutting down nuclear reactors, the only current viable alternative to fossil fuel power plants, they ensure we use more coal and oil power plants, contributing to the environmental change they love.

      Many Jellyfish and Fish compete in their ecological niche. Because people the world over are over-fishing the sea, it leaves room for more jellyfish to snatch the food the fish would otherwise eat. Furthermore, Jellyfish are also nearly nutrition-less so people do not try to catch them. So, we have a collection of species of animal that have less predation vs. their main competitor and more food to eat, so they tend to thrive. Its not really a good idea for us to continue to ravage the sea life without regard to their continued survival. Coal and Oil plants really don't affect the Jellyfish as much.

      Historically, we didn't have a population problem. China reflects the population growth of the entire world. Until about 1850, population growth was a stable thing, growing fractionally every century or so. After about 1850, we saw this exponential growth.

      The reason I picked China as the example, is that China has made a conscious effort to control population. One couple, one child. Negative population growth, which should put China comfortably within the land's capability to support their population within the next 100 years or so. (Sorry, no, I haven't researched projected population figures - I'm just guesstimating that 100 years from now, China's population will be (very roughly) about 1/4 what it is today.)

When I look at history, I see a lot of nations invading others for food, for wealth, for crazy religious reasons, and to satisfy a desire for conquest and blood lust. China? They have had 1/4 of the world's population for millenia, I guess. Back when the number of warm bodies on the field pretty much decided the battle, they could have expanded anywhere they wanted. But, they didn't.

      What I think is more likely to happen is, a lot of young men are going to emmigrate from China. China is right now building something of a financial empire across the rest of Asia, Africa, and reaching into Europe and the Americas, along with Australia. It would be perfectly reasonable for China to export young men to those nations for business reasons. And, while they are out and about, they may find that the local women are rather attractive, with the added benefit that the local governments don't care to much about the number of children you have.

    Some of the divers discovered they could get even warmer by sticking the hoses into the neck of their wetsuit. After a few weeks of doing so, a number of jellyfish swam near the surface. You can probably guess what happened next -- one of them got sucked into the pump and shot through the hose, straight down the back of his wetsuit and settling right between his legs.

    It took a few days before he was able to walk after that, and probably a week more before he could do it comfortably. I guess he was lucky they weren't a more deadly variety, and that he had a buddy nearby to help him surface and remove his wetsuit.
