I don't have any fear of 5G but I've read that people have problems growing plants around current wireless connections. It's anecdotal and I've seen other people grow things that have wireless.

We should always be aware about what new bandwidths we use affect nature. If we screw up the bees or bats things could go bad quickly.

New tech is great, but we use it like a horny teenager. We just want to jizz all over the place with our new tech without thinking about all the long term consequences.
