small impact on butterflies?

a nice image that showcases the "small" impact of the human race on this planet:


if this would be cancer, we could concider this our last day

i personaly dont buy the "small matchbox in the big atlantic ocean" theory. pollution is a missive issue and we are running down this planet faster then you can say chaos theory.

can mankind cause massive and global pollutions or climatic changes? maybe the picture above can bring some light into this issue.

cheers

The *fact* is, most scientist think that the world is warming up, that this is generally bad for the human race, and that it is caused (at least in part) by us.

Yes, they could be wrong. Yes, you can find scientist that disagree. Yes, this could all just be nothing. But, there is a *really* good chance that they are right.

To continue the cancer analogy, if you found a big lump on you neck that didn't go away, would you just hope it was okay or would you go to the doctor?

Now lets say a dozen doctors looked at it. 11 of them said it was life threatening cancer and it needs to be removed at once. Doctor number 12 says it's probably cancer, but it could be something else. Oh, BTW, this doctor works for a man who runs a toxic waste dump in your backyard.

The fact is that most scientists who were saying that there was no global warming are now acknowledging that there is indeed something amiss...

The sad fact of the matter is that most of these "scientists" are usually people backed by larger companies with a vested interest in the said scientists "findings"...

You have to be very wary of where your source comes. I'm sure, somewhere, there's a middle ground. But let's be serious for a second...

The middle ground between nothing wrong and...
The end of life as we know it?

Hm? >_>

Yes, people like to bring up the "global cooling" scare of the 1970's. Do you know the story behind that?

Between 1940 and 1970, scientist reported that there was a cooling trend. In 1975, Newsweek picked up the story and warned that we where heading into another ice age (this is what most people quote).

The funny thing is, the 1974 report this was based on goes on to state that: "the present time of high temperatures should be drawing to an end" but "human interference has already altered the environment so much that the climatic pattern of the near future will follow a different path".

In short, the earth should be cooling but it isn't because of human involvement. We've stopped an ice-age and now we're over correcting.

Do you mean that human impact is so strong that it can even overcome the forces of the nature ?
I have no arguments against this hypthesis but it seems a little strange
Moreover it is a matter of fact that cold periods have been followed by hot ones and viceversa
The chronicles from middle age till nowdays leaves no doubt about this point
