This. As with most initiatives, extremism kills good ideas. Plans for carbon-free solutions that are so impractical to implement, or only in a far future, is a dead end. What we need now is to stop theorizing and take immediate measures to reduce the footprint of the current supply chain, mostly by rationalizing global exchanges (many raw materials are sent from A to B to be transformed/packaged only for the final product to be sent back home to be sold). Further decarbonization can also be reached in a reasonable future by retrofitting current ships with rotor sails to save fuel on windy days without impacting regular operations. The rest is science-fiction, and a waste of time and energy.

Reply to This Startup Turned 1 Million Pounds of Ocean Plastic Into a Highly Profitable Business by RedditModsAreAPlague

Might be profitable, but definitely not green nor sustainable. It only works because so far there are enough first world hipsters to buy that crap at an outrageous price to allow for a profit margin. Meanwhile the whole process uses way more raw oil than making the same items out of new plastics or even burning this shit and making new items out of purely organic materials. On the other side, it doesn't even clean up shit because of the insignificant volumes and the used newly recycled items will end back in the sea or ground water anyway, since the recycling chain is far from getting fixed.

Might however be riddled with issues tied to the natural decay of frozen DNA over 30 years. We don't have any data on such live experiments. They can - hopefully - be just fine, or suffer from yet unseen genetic diseases developing with age.

AFAIC I see no reason for a frozen piece of DNA to be healthier than one that has been naturally replicated with new material over and over, despite this occurring in a less than optimal environment.

Reply to Extreme heat will change us by SigmundFreud

Wait to see how we will get changed by depleting natural resources, including end of cheap energy and access to fresh water for the majority of us, in a world utterly polluted with microplastics and heavy metals.
