In South Africa alone, around 7.5 million people do not have adequate housing (
https://www.homelessworldcup.org/homelessness-statistics/). the great majority of these people believe, due to political mistakes both past and present, that they are entitled to housing, land and jobs.
These people have no understanding of the importance of nature in our own survival. Nor do they have any interest in nature, and virtually none of them can afford to travel to a nature reserve or anywhere else they may see the beauty of wild animals.
For them, any area reserved for conservation is land they feel should belong to them. The animals look like a good meal to them. The fact that most of these areas are too dry to farm, and will be destroyed in short order if they try to farm it is totally beyond their understanding.
Our government, since 1994 and before, has been promising them land and jobs, which promises they have largely failed to deliver on. In the latest (unfortunately only municipal) elections, the ruling party has lost a lot of ground, and they are now scrambling to recover their lost ground. Recently, they have been mooting new legislation such as "use it or lose it". The purpose of this legislation is that ground which is not earning income will be repatriated and re-distributed.
This is our reality, and it is not a unique reality either.
I realize (and gladly so) that things are different in Europe. However, that knowledge does not solve the problems in Africa, India and South America, the very places where most of the biodiversity is.
Here, we need desperately to find ways in which nature can be saved, and the only likely contender at this stage is if the earnings are greater than the cost of the loss of conservation land to agriculture.
