US Navy (and certainly others) kill many dolphins, whales and other sea life with their high powered sonar.
US also has high powered ultra low frequency radio (ELF) for communication to subs and that's got to be insane to wildlife.

- dingnuts 2y agosound and radio are of course waves in completely different media. why would low frequency radio waves be insane to wildlife? it's not like it's microwave (which would cook them) or pressure (sound) which directly physically damages their organs. almost by definition low frequency radio waves are low energy, so I don't see how this would be more dangerous to Flipper than my Wi-Fi router is to me
- d3w3y 2y agoWell, some people do think their Wi-Fi routers can hurt them ... maybe we should make tinfoil hats for the cephalopods.
- bee_rider 2y agoHuh, sharks pick up EM signals, right? I wonder what they think of this stuff But just to be clear, I don’t think we should suppose it is damaging and try to ask the military to stop using it (good luck, lol). It could be worth looking into though.
- nativeit 2y agoI mean, we all pick up EM signals. The frequency range is the distinction, I think.
- bee_rider 2y agoSure, but sharks use them as a sense. We all pick up photons in the sense that we can all feel the warmth of the sun on our skin, but also, it is sometimes interesting to think about how people who aren’t blind perceive light.
- blackeyeblitzar 2y agoI’m talking about sound not electromagnetics. It’s like a torture for marine life to be surrounded by constant noise. Many also use sound to communicate or locate.
