I strongly believe that the Seed bank is not a waste of money because…
Firstly if we run out of seeds we will have a storage place and they will be protected.
Secondly The vault needs a lot of security so that people can’t get in and wipe out whole species of plant! if that happens not just plants will die but animals too!
Furthermore if one seed bank gets wiped out then we will have another one to help the other one restart its seed collection so that we will never run out of seeds.
Thats why i think that the seed bank is not a waste of money but a thing to spend more money on.
