The giant jellyfish in China are ruining the fishing industry now.

Millions are being spent, and it's still not enough.

It's a huge problem, species are moving into new areas.

symp: are you feeling better? i hope so. sounds like you had a bad time there.

Hi Symp!!!!

Again, I'm NOT saying that we have NO impact. We certainly do. But not as much as we may think.

Hey Gryph!!!

I understand. I think maybe you're saying what ever happens to the earth, from us or the earth's own changes, the earth may start the cycle of life over again.

Even after we may be gone. Do I follow?

They still can't fish in China. /laugh.png' class='bbc_emoticon' alt=':P' />

I guess it's do to the warming, waters.

I'm NOT saying people caused it either.

As I believe it's all Al Gores fault. /laugh.png' class='bbc_emoticon' alt='' />

I think it's some of both, the earth changing and people having some type of an impact.

The view seems globalized, as what is happening to the earth as a whole.

I'm a speck on this planet. I'll think in simple terms, and what effects I've had directly to the earth.

I have a septic system, it leached into my well water.

Springs flow under ground, and my sewage may have went into the springs also.

I left an impact. Maybe on others drinking water, due to well fed springs.

Think about it, I did not have to report this to any goverment agency, which I thought odd.

How far did my sewage travel?

We explained to neighbors and suggested they get a well test. We test ours yearly.

I wondered, as this happens who knows.

Although I don't agree that mankind and industry is the root cause of "global warming" I do agree that the earths climate is changing. Can cleaning up our dirty wasteful ways make a real difference in the climate – I doubt it, but what would result is cleaner air, cleaner water and less garbage accumulating in landfills – and I think everyone will agree that would be a good thing. The problem is that a few scientists, governments and loonies are fear-mongering rather than selling the masses on the real good that can result from change.

Then we should consider if making a change in our lifestyles could assist is lessening the impact of lets call it a normal global warming cycle and whether might be worth it or not. Will an increase in temperatures a 1/4 of a degree add to the rising sea levels enough to make Venice, Italy a ghost town because of the flooding that would result? Would it turn the great barrier reef into just a giant rock wall killing off the coral because of deeper water. With the diluted salinity of the oceans, what will be the increase in cost of shipping because of reduced buoyancy of ships?

But if this carbon credit insanity comes about, I'll tell you here and now that I will raise holy hell when they tax or remove the CO2 from my Dr Pepper! /angry.png' class='bbc_emoticon' alt=':unsure:' />
