Re: Electric planes?
"Do you also believe that we are currently proving that we don't need restaurants, pubs or sporting events?"
Well yes. They may be nice to have available, but there's obviously no actual need fo them to exist. If you can't go out for a meal, you can still very easily avoid dying of starvation. And if you're not able to fly from the UK to Australia, you can very easily simply avoid doing so, no matter how much family might be at the other end.
The difference is that pubs have very little environmental impact compared to eating at home, so there's no reason to worry about them opening back up once this lockdown is over. We absolutely have proven that we don't need them, but we want them and have little reason to oppose that want. Planes, on the other hand, do have some serious downsides to their use. And since we've proven that we don't need them anywhere near as much as some people liked to use them, maybe we should think a bit harder about going back to previous levels of use as soon as we can.
