I'm not an expert but blocking UV-B may have some negative consequences.
- uoaei 4y agoImagine a world where bees can't see the centers of flowers.
- adastra22 4y agoBees see with UV-A light, not UV-B.
- uoaei 4y agoBees see with both. UV-A (320-350nm) and UV-B (290-320nm) both overlap with bee visual spectrum (300-650nm). Do you have data on which flowers in which geographical areas reflect with UV-A and/or UV-B? Maybe to bolster your argument you will need to prove that this won't affect bees, and pollinators more generally.
- adastra22 4y agoThe harmful UV-B rays are under 300nm, and that’s the cutoff for bee vision for the same basic biological reason. Below that limit is what you’d want to filter out.
- adastra22 4y agoIt does not. UV-B is ionizing radiation and is incapable of being used by biological processes as a source of energy. About the only effect it has on our biome is that it contributes to the production of ozone, and it is possible that filtering out UV-B might reduce (but not eliminate) the ozone layer. However the main/only benefit of the ozone layer is to filter out UV radiation, so... UV-B is like mosquitos, one of those rare things that really only does cause harm and can be safely eliminated if possible.
