A world without diversity is fragile. This is true for vegetables, cattle and even us. Genetic diversity is a barrier to the spread of virus, bacteria and other parasites that cause diseases.
'"Another danger of a more homogeneous global food basket is that it makes agriculture more vulnerable to major threats like drought, insect pests and diseases, which are likely to become worse in many parts of the world as a result of climate change." As the global population rises and the pressure increases on our global food system, so does our dependence on the global crops and production system that feeds us.'

- adrianN 9y agoAs far as biodiversity goes, those "forests" are already pretty much dead.
- toomanybeersies 9y agoUnsurprisingly, pine trees with all the lower branches stripped, laid out in a 5x5 metre grid, are not a great environment for promoting biodiversity.
