Pollinator Park is a sort of virtual botanical park tour created by the EU. The idea is to show us “what a world without pollinators would be like”. It sounds and looks cool, but didn’t load correctly in my web browser. It is also supposed to work in Oculus Rift, which I am sure is cool. There are some nice pictures in this Inhabitat article.

I have certainly heard that pollinators, and insects more generally, are disappearing, not just on a species diversity basis but on an absolute biomass basis. It makes complete sense that the loss and fragmentation of natural habitats and native vegetation would lead to a loss of insects. Pollution, agricultural chemicals, and climate change (heat/drought/fires/floods/storms) can’t be helping. I have seen at least one dissenting paper on insect loss however and would like to understand the evidence for it better. But taken at face value, it is very concerning. Pollination is undoubtedly a critical ecosystem service that we can’t do without, and this is fairly easy to understand. Unless we can go to some kind of high-tech indoor agriculture, which currently would not be a feasible way to feed 7+ billion people.

I’d also like to understand to what extent it is important to preserve some natural habitat and native vegetation (or other pollinator-friendly vegetation?) in the midst of farmland to maintain yields. What size and what shape should these habitat islands or corridors be, and do they need to be paired with specific crops? More esoterically, if you change the type of crop being grown but leave the insects and vegetation in place, does the ecosystem service value diminish? (economically, yes, but logically and morally, this makes no sense to me and I think it helps illustrate the limits of the economic approach.) Could these designed/managed habitats act as useful buffer/transition areas to more natural preserved areas? Or would they do the opposite, importing non-native plants and animals that would have an adverse impact? Can urban and suburban parks and gardens play a meaningful role? Or is it hopeless and only trying to preserve vast swathes of untouched wilderness would do? (maybe add a placeholder for this on our next planet.) Should we be releasing vast swarms of genetically modified or self-replicating robot insects? (I’m going to go with no!)
