The only sustainable resource for energy from seawater is heavy hydrogen for nuclear fusion.

The lungs of the planet are in big trouble

This planet was not built for 7.9 billion people. Maybe not for even half that number.

And the right number is?

Actually an interesting question. I read somewhere that a stable and above all sustainable human population would be at around a billion.

That probably depends on how they want to live.

AFAIK, the average person in the US uses 50 times the energy (and resources) than the average person in Bangladesh.

I doubt this planet can sustain 5b people living like Swiss or US-Americans...

It's all easy talking about reducing the population, as long as "the others" are meant...

Man made Climate Change is a real issue that needs to be confronted and addressed in an appropriate and proportionate manner. Climate Change Armageddon or "Climate crisis" is just fear mongering nonsense that doesn't help the situation and leads to lunatics like Extinction Rebellion getting air time.

…Memento Mori...

Thanos was wrong, not only half of the population, we like to bone way to much and the numbers would be up again in a flash.

Why is it that some idiot has to put an image up that's larger than my screen?
Talk about climate change! what about thread change?

If you use an adblocker (who doesn't?) you may be able to block it. Rightclick on it and see what options you got.

Given that we created it, we should be able to do something about it, yes.

I am curious, where do you plan to store that water after you used it?

Haven't you listened to Greta:

“The world is going to end in 12 years if we don't address climate change.”

I actually think it's a good thing we are waking up as energy security is critical and renewables will be cheaper than fossil fuels.

Got an extra pack of TP the other day. Just in case.

Unless the process is already runaway and we are now just along for the ride.
I´m wondering if the economic consequences of Corvid will be used to overturn efforts to curb climate change.

Hehehe .. good one.

Even if we don‘t know, does that mean we shouldn‘t be trying? There are so many places to start.

Less is often more. Our consumption habits are wasteful, as they are in most rich countries. If some statistics make Switzerland look good, that’s because they fail to take into account the grey energy for the goods we import from the Far East. Fast fashion is a problem. Zurich alternatives: 2ndpeak.ch, thenewnew.ch, rework.ch, chemiserieplus.ch, caritas-secondhand.ch and many more available everywhere, such as Patagonia, Hessnatur, Changemaker or Avocadostore. We have a teen at home so we‘re working on it :-)

Plus, Switzerland‘s fleet of cars consists of the heaviest, most luxurious vehicles in Europe. And no, that’s not due to the mountain dwellers; your average Alpine farmer drives a sensible Subaru. Safe bike lanes would be a huge improvement and allow seniors and schoolkids to get regular exercise in the most efficient way possible, and not just the young kamikazes that Zurich‘s pedestrians love to hate.

As for Swiss agriculture, it is is hidebound, if you‘ll pardon the pun. We can produce almost the whole amount of meat and dairy we eat inside the country, but not nearly as much fruit and vegetables - which would generate both more calories and less CO2, as well as fewer pesticides and nitrates. By now, we all know about glaciers melting, but did you know that the Baldeggersee has been artificially ventilated for decades? The idyll is often superficial. But farms are usually passed on within families in Switzerland, and farming families traditionally feel represented by the SVP. Need I mention the votes in June? 3x yes if you can - thanks!

Somebody mentioned nuclear power. While that‘s better than gas in terms of carbon emissions, fuhgeddaboudit. Even a massive push for renewables stands a better chance, though/because Switzerland is far behind most neighbouring countries with solar and wind. We figured hydro put us ahead of the field. That was true, but it has made us complacent. We can and must do better. There are miles and miles of unused rooftops ideal for solar power generation. And that‘s just the low-hanging fruit. Wind is more difficult here but I‘ve never understood why. Not even Landschaftsschutz Schweiz fights every windmill.

The same person mentioned gen-mod crops. While I appreciate the theory, it‘s often ugly in practice. Farmers getting sued for plants sprung from their neighbour’s seeds. An unhealthy dependence on global corporations with more power than either small farmers or their governments. Did you know that a mind-boggling estimated one third of our food is trashed instead of eaten? I‘d suggest taking on food waste first. There are many good initiatives, see foodwaste.ch.

(And to state the obvious, we haven‘t set foot on a plane in years.)

Excellent question. I beg to disagree: https://finance.yahoo.com/news/risin...090000627.html Seems to be limited to the US. The south coast of England is crumbling in several places, too. Here‘s one: https://www.bbc.com/news/uk-england-dorset-28898711 And... Venice? Are those super-duper new flood gates working yet?

My favourite „Curse for Jewish Republicans“: May you sell everything and retire to Florida just as global warming makes it uninhabitable. (Yes, it is that old - dates from the days when they didn‘t call it climate change yet.)
