You are absolutely right about the Human Population Growth being the root cause of a lot of our own problems. And you are right about mother nature being the final arbitrator of this. We may pollute our shelves to death or have mass starvations due to hunger and disease.Originally Posted by kygorski
The earth only has a limited carrying capacity and that varies in different places though out the world.
It's impossible to think that man's activities is not having an impact on our plant. How much of an impact is debatable but an impact non the less.
What many don't really comprehend is that even a small change in the Average Global Temperature of the Earth can have a huge impact on certain areas of the planet. I think that super storms Sandy and Katrina were just small examples of what could come in the future with a warmer Earth.
Warming of the Ocean's by just a few degrees can change ocean currents which can have a huge impact on certain parts of the Globe.
We do know that the amount of Carbon Dioxide in the Earth's atmosphere has changed over time. We can extract ice cores from glacier that have been around for over thousands of years and measure the amount of CO2 that's frozen in the different layers of the ice. That tells us that the lower (older) layers of the ice have less CO2 in them. We do know that increasing levels of CO2 makes it harder for heat to leave the earth's atmosphere.
I really have no dog in this fight, I'll be dead long before this all really starts to affect me and I don't have any kids to worry about in the future. I'm just saying!
