A New Superhero! Enviropig!

Well, not quite.
The Canadians have made a pig that is better for the enviroment, though. The problem with pigs is that they have to eat a diet of barley or corn. These plants are very high in phosphorus, which cannot be digested by the pig. This element then is released through poop into the ocean and causes dead spots. That's why the U.S. has made a no tolerance rule against pig poop, which costs farmers because they have to spend a lot of money to contain the excrement, which hurts the economy because the farmers have to raise their prices. But hopefully, that will soon be a thing of the past thanks to the Canadians. They've made a pig that can digest phosphorus and pass this trait on to their offspring, to at least eight generations down the line. They did it by splicing the neccessary sequence onto a mouse promoter and then injecting that into the embryos of several pigs. It will take a while for these pigs to be legally farmed in this country, but it will happen. I think this is a good idea, it will stimulate the economy and save the earth. Dead spots are slowly draining the fish supplies, so any way to fill them up again sounds good to me.
Phew. Blogger wasn't working for a while, I'm glad i was able to do this.

Go around the Swallows!

Hello world,
South Africa is the main nesting site for a whole lot of European swallows for several months of the year. They come there to breed. The problem is, is that an enormous amount of humans will be flocking there for the 2010 Football World Cup. The airport that they will us is the King Shaka International airport, which is right in front of a huge nesting area. Thankfully, conservationists have been working with the developers and have come up with a solution. The nesting area is below the takeoff strip, so with a little help from a radar system, the control tower will be able to tell when the swallows are flying high enough to get caught in the planes jets. There will be plenty of time to perfect the system before the airport opens on May 1. I think it's wonderful that they worked this out instead of just killing the swallows off.

Off With Knut's Nuts!

Hello world,
Several years ago in Germany Knut the polar bear was abandoned by his mother. Now the German branch of PETA is calling for him to be castrated. They argue that otherwise Knut would mate with his cousin, Giovanna, who shares an enclosure with him. That would decrease the genetic diversity of the bear population, and cause incest depression. Supposedly, the castration would help him be able to continue to live with Giovanna. Personally, I think that if they're that worried, they should just move him.

Transexual Frogs

Hello world,
No really, they can change genders now. The Common Reed frog has been known to do this when there aren't enough males, but that is good for the species in general. The sex change that the article talks about is a chemical induced change that is bad. It's caused by the weed killer atrazine. It decreases the level of testosterone and can make the frogs turn female or become sterile. This, along with habitat destruction, is probably helping along the frog extiction process. This is very unfortunate for frogs and their homes, for frogs help keep insects under control and provide food for many creatures. I hope they put a ban on atrazine, for if it can do this to frogs, it might do something bad to humans.

Bear competition

Hello world,
Grizzly bears have been spotted in Wapusk National Park, the bear capital of the world. Most scientists agree that the grizzly migration has more to do with a growing number of bears rather than global warming. Some even speculate that the polar bears would be making room for their cousins within the next century because of the fleeing ice. Polar/Grizzly bear fights are expected to not happen often, because most polar bears leave the area before the Grizzlies wake up from hibernation. Some even hope for grizzly/polar bear hybrids. I do think this is big in the bear world, but I think the polar bears have bigger fish to fry (so to speak)
