power balance bands

I think that power bands have very little affect. I also think its in peoples head that it works. You don't need a bracelet to be great at a sport. I would test this by having a person blind folded and put a regular jelly bracelet on them first and do the balance test and then put the power band on and do the same test and ask the person if the first or second bracelet had any effect. I think that its important to look at all sides of the story because one thing could have a greater affect then the other.

the aqutic ecosystems

The health of the aqutic ecosystems are in very bad conditions. there going to start to be a lot of limiting factors going to take place in a few years for example, The biotic factors have changed so much that habitats  are becoming extict. Also some of the abiotic factors are also starting to die. Most people are hopeing that primary succession might take place over time. My connection to the aqutic ecosystems are that people drink from there and it provides us food. I think the rule us hummans play in the biosphere is not good, we need to be more careful on what we put into the air, because if acitic rain continues to poor into the oceans our and there resources are going to start to die. I dont think most people know what they do every day hurts the ecosystems if this keeps up theres going to be a lot of competition going on and less mutualism going on. There will also be more predation in the aqutic systems. There may or may not be as much symbiosis in the sea. There will also be a lot more immigration and emigration happening because of globle warming.
