The dangers of phones. And bears.

When our species begins to decline in numbers, I do not think it will be due to environmental degradation or war or bears.

Those issues are certainly things to stay up all night worrying about, perhaps in a fortified bunker in your basement. And if you think bears aren’t a concern, remember that they can outrun us, outclimb us and outswim us. And we’ve spent decades teaching them how to ride bikes. We’ve created a potential monster.
