No, this isn't mistakenly left out of the conspiracy theories.

Alien species are plants or animals that are invading non-native lands.

A good example of this are the new crab species inhabiting the New England shoreline, including the Green Crab and the Asian Shore Crab. They threaten the native populations of crab because they add to competition for food, (natural resources), they out-breed native populations, (guaranteeing that their genetics as a species are passed on) and they are aggressive.

How do they get here? Shipping, they take a cruise.

An alien plant species can cause a disruption in the food chain, based on the spread of it's dna as it interacts with the local fauna and flora.

Underwater Vac Inhales Alien Algae
Tracy Staedter, Discovery News

Sept. 25, 2007 — Alien algae are infesting and killing some of Hawaii's coral reefs at an unprecedented rate. But a new underwater vacuum cleaner is helping curb the growth.

Dubbed the Super Sucker, the machine can hoover up to 800 pounds of the thicket-like algae in an hour, which should give reefs a fighting chance of recovery.

This should also give people hope that there are things we can do on a major scale to effect our environment in a positive way. I hope this works as coral reefs are so important to the diversity of ocean life.

So, don't give up on humanity's ability to cause change it all, cure cancer, aids, end global warming and feed the hungry. When we put enough of an effort into improving or preserving something, we can make the world a better place for all.

Hmmm... that really sucks.

I watch the high def Planet Earth series on Discover. Our oceans are in big trouble. I'm a bit of a "greenie" and this is kinda on my radar.

I'd love to see us be able to keep areas in the ocean that are dying alive, but I think that it is the natural process of the world for changes to take place, resulting in new species.

I am wondering if we are not developing new forms of life, hidden deep within the depths of the ocean, in reaction to the changes that are taking place on the surface of this planet, perhaps even some of the newly discovered sea creatures that were washed up in the tidal wave catastrophe.

We do know intelligent life lives in the ocean already, whales and dolphins, able to communicate almost telepathically. Who is to say what will emerge, someday. I hope humanity someday is able to witness something amazing, something that makes so much of a difference in the life of every person, that our species is finally able to experience peace.
