Hi @Tahr, in answer to your request for evidence for my statements: Paragraph 1 - 1080 poison is cruel without doubt so well proven that I don't believe you would debate that point. The same for the poisoning of vertebrates and invertebrates alike.
Para 2: If you look at the extinctions of birds like the NZ Native Quail Coturnix Novaezelandiae , this bird was common across the Nth Sth and Great Barrier Islands, so common that daily bags of 100 were easily shot. Then simultaneously they disappeared. Bird life international lists the cause as 'diseases from introduced game birds' The following link will show you how extensive the problem is - http://scholar.google.co.nz/scholar_...l=1&oi=scholar
The inland sanctuary Islands is a 'no-brainer' we already see how these work - how birds move to safe areas to breed and then move out into the wider area. The same concept can also be seen working with marine sanctuaries.
