wrote: That does not alter the fact that on this planet non-plant life is wholly dependent upon plant life, Bacteria and microbes which feed upon manganese deep underground or the searingly hot acids emitted from volcanic fissures on the sea bed might argue with that. but not vice-versa. So the loss of pollinating insects, rodents, bats, primates and birds to which certain plants have adapted specifically will not have any adverse effects upon those plants then? There are hundreds if not thousands of plants that have adapted to very specialised pollinators and if those pollinators disappear, then so do the plants. A widely known example is the Yucca which flowers prolifically here in the UK, but cannot set seed since the moths which assist with the flowers' pollination are not present amongst our fauna and could not exist in our climate. If those moths disappeared in their native habitat, so would the Yuccas eventually. Many valuable tropical species (my favourites the bananas come quickly to mind, but there are many more) are bat pollinated. Wipe out the bats (and they are becoming highly endangered in many regions) and the plants disappear. No, you are wrong, there is a powerful necessity for co-existence for without one there will not be the other. You cannot make such sweeping statements that plants can exist without animals, because ultimately flowering plants are dependent upon animal life.
