My point simply is this: some people do what they do because they need the money. I think it is a bit naive to imagine that there will be "organisations" around to help these people. There is sometimes a disconnection between the lofty aims of these organisations and what actually happens on the ground.
All that I am saying is that, to someone in a developed nation like you or I, plant conservation may appear to be very important. However, to someone else in a rainforest village in the middle of nowhere, would he care so much for the conservation of plants at the expense of his family?
Perhaps I am painting a very extreme picture. But it is important, in the inter-connected world we live in, to realise that perspectives of "wrongness" will differ between different cultures. IP laws are another good example. While countries such as the US have argued for the enforcement of IP rights, countries such as China have been slow, in practice, to do so. There is a discord not between the desire to obey laws but what the law actually is in the first place.
