But I think the same complexity is what makes them beautiful, he said. In what theyre calling a modern global insurance policy, mechanical engineers have proposed that humans establish a repository of reproductive cells  sperm and ova  from 6.7 million of Earths species, including humans. In what theyre calling a modern global insurance policy, scientists have proposed a lunar bank of reproductive cells  sperm and ova  from 6.7 million of Earths species, including humans. The group hopes to send 6.7 million species to the moon, representing up to 90% of all known plants and animals, minus those that cannot be cryogenically preserved, he said. 'Now we're leveraging it for other scientific applications,' he said, adding that there are likely further uses for this type of data.
Now they are trying to preserve a moon bank.
( z0 try :ARG0 ( z1 they ) :ARG1 ( z2 preserve :ARG0 z1 :ARG1 ( z3 bank :mod ( z4 moon ) ) ) :time ( z5 now ) )
(z0 / try-01
    :ARG0 (z1 / they)
    :ARG1 (z2 / preserve-01
              :ARG0 z1
              :ARG1 (z3 / bank-01
                        :mod (z4 / moon)))
    :time (z5 / now))
Now they are trying to preserve a moon bank .
z0 :ARG0 z1
z0 :time z5
z0 :ARG1 z2
z2 :ARG0 z1
z3 :mod z4
z2 :ARG1 z3
