UK Professor Tom Curtis : I make no apologies for putting micro-organisms on a pedestal above all other living things, for if the last blue whale choked to death on the last panda, it would be disastrous but not the end of the world. But if we accidentally poisoned the last two species of ammonia-oxidisers, that would be another matter. It could be happening now and we wouldn't even know - Halil

Jenny and Hookuh Tinypants have said this to me many times in our chats, I've stop pestering them and others with my endless science questions now, lol, I bet they miss it, haha! ;-) - Halil

Ha! You're never pestering. :) You're passionate and that's cool. :D - Hookuh Tinypants
