A modern airplane may not be perfect; they still crash every now and then, but in regards to transportation, they beat the hell out of Orville and Wilbur Wright's contraption.
"Any green, renewable, energy technology must be in harmony with nature."
But it won't be. Our environmental impact increased when we used sharp sticks to hunt. Let alone what we'll end up doing with our green, renewable, energy technology.
Green renewable energy will be far more in harmony with nature than our current system of burning the remains of long dead corpses and putting that into the air, water and land. Green renewable energy relies on the ever giving properties of life, with finite fossil fuels we're reaching a dead end in both supply and environmental sustainability.
"I believe as the world industrializes under green energy, populations will stabilize."
There will have to be some downside to that as well. We'll have to give something up to get that. Something that we like. Not just giving up too many people on the planet.
Population stabilization is just one aspect of existing industrialization in general, having green, renewable based industrialization population stabilization would vastly improve the current situation, but if you can think of a negative or adverse aspect, name it.
"I do disagree with you on one aspect, it is the kind of energy we use, solar, wind, geothermal would not do anywhere near the environmental damage of nuclear with it's toxic wastes and potential catastrophe or fossil fuels and their own toxic waste."
From the toxic waste perspective, sure. That's not the only way we do damage though.
Toxic waste has the capability of wiping out large portions if not all of civilization, so I consider that a pretty big way to do damage and that's just by accident and/or everyday use while not taking in to account the effects from a terrorist strike. With global warming climate change, we're literally threatening our own existence, I have never heard of solar, wind or geothermal energy having the capability of threatening life as we know it, if you have please share it. If you're coming to a fork in the road and down one path you can see imminent, overwhelming danger, it makes sense to go around the danger and change paths; if another looks much more promising without having to know every possibility about the new path, to do othewise would be illogical.
