Think thylacine now and how the "theorists" maintain in earnest after nearly 75 years the species still "exists" without any documented trustworthy visual observations. What most of us as yet seem to forget we already live in our future past with the extinction threats a reality for a majority of wild animal and plant life and we require a change of our mind set from lamenting it, talking about it to changed behaviour in terms of us living on this Planet amongst so many other species and in so varied habitats and environments. Not Knowledge, but Action and Passion make that change. Just ask yourselves what can I bring to the table, that is doable, comes naturally to me and is part of that change and I can sustain that till the problem is fixed.
