In case people are curious about this claim the reason Germany's "renewable energy" releases so much CO2 is because a large portion of their 'renewable energy' is burning wood.
Burning wood isn't "net neutral" until trees live over 100 years. Until then, it's worse than coal. http://www.pfpi.net/wp-content/uploads/2014/04/PFPI-Biomass-...
Most tree farms don't let trees grow 100 years either.
>Based on consumption trends in our region, using wood to generate power here or to make fuel pellets for power generation in Europe is projected to produce higher levels of atmospheric carbon(300%) than fossil fuels for 35 to 50 years. After that time, carbon levels will begin to fall as regrowing forests absorb CO2 from previous combustion, but it is likely too late to avoid irreversible effects on the climate system.

Now more seriously:
The human race would easily survive without seafish. Maybe in smaller numbers, but for example in the inlands people eat much less seafish, as they don't have seas nearby ;) A century ago not much seafish was available in the inlands, yet the European inland population was comparable in numbers to the current population.
Radioactive materials were in the ground already, and have been solved into water, which people drank, and had comparable life expectency (shorter, but also due to numerous other factors).
Poisoning the wells and ocean is not very good, especially for business, as many people are irrationally afraid of radiation, and even suspicion of possibility of radiation hurts just as much as actual hazardous contamination to the sales of a product. Apart from that it would truly cause large economic problems, as large areas would have to be excluded from agricultural use, yet nothing like extinction would happen. Even after Chernobyl some people are still alive in Eastern Europe. Even animals live mostly happily in the zone...
If you really want to go down that route then the human race can easily survive without clean air, water, ground or any animal life on this planet. Why would we need any of that? We, at least a few of us, could just as well be living in sealed underground bunkers powered by thermal energy while eating mushrooms all day and recycling our pee and sweat. Doesn't that sound like a lovely future? ;)
>A century ago not much seafish was available in the inlands, yet the European inland population was comparable in numbers to the current population.
They didn't need seafish because they did have enough land for agriculture, many other places, especially insular nation states and Asia in general, did not and do not have that luxury. I also doubt that current European inland population numbers are in any way comparable with the population numbers of a century ago, back in 1900 global population didn't even break 2 billion, now we are at over 7 billion.
That's ad hominem, Tex
