William Ryerson freaks out about population growth:
The combination of rising oil prices and declining water could lead to a perfect storm where suddenly all these things lead to human catastrophe around the planet. A report that came out in the last couple of months by two biologists looking at global biodiversity has shown that biodiversity is declining globally and the 100,000 preserves that have been set up are doing nothing to protect biodiversity. Spreading human habitation is systematically reducing the life support system of our planet. Cutting down large rainforests is a major aggravator of climate change. It took 3 billion years of evolution to make our planet habitable for humans. Setting up large zoos – which is what reserves are – isn’t going to protect us. We are risking the long term habitability of the planet. Some scientists think that humans could be extinct by the end of the century.
Erik Loomis thinks global inequality is the bigger environmental issue. Marc Bellemare is exasperated by the negativity:
[I[ncreases in agricultural productivity have consistently outpaced the rate at which the world’s population continues to increases. This has been true since the beginning of time, so why worry now?
Joshua Goldstein downplays the fear that we might start to fight over resources. Previous Dish discussion of the 7 billion mark here, here and here.
