I just love the idea of conserving the DNA of ‘all life on earth’. Are they serious? Do they have any idea how many species there are (the answer is no, nobody yet one knows how many species there are, it’s a work in progress), but we do know it is a large number. There are, for example, as many as 10 million different marine bacteria, 35,000 species of spiders (known –probably many more to be found). Are they proposing to conserve pathogens and parasites, and if not who gives them the right to decide what to keep and what to lose? And even if you could conserve all the DNA of all the species in the world, what good is it. DNA doesn’t do anything on its own, its not a magic life force just a rather long polymer. Each species has its own evolved machinery for making DNA work, and without this machinery the DNA is only marginally more interesting than nylon
