Maybe something like taskrabbit? Could pay them to pick it up, then send it through a courier.

I have little to comment on regarding the motivation for your post – I am not up to date with what’s happening in the EU – but, for an encrypted messaging-app alternative to Signal, I can recommend Matrix.

This isn’t necessarily about the sheer size of population, and has more to do with birth rates, but this Kurzgesagt video also outlines well the need for a higher birth rate.

Almost all countries need to reduce their population.

On the contrary, actually, we need to increase our populations. Assuming that you mean an equal reduction in all demographics, the existence of productive, and hyper-productive people is mostly a game of statistics. A larger population means that more of such people will exist. Such individuals are necessary for pushing humanity forward. A nation with a larger population means a larger natural defence. A larger gloabal population decreases the chances of a mass-extinction event.

it’s stressing the system.

What specific stresses are you referring to? We have no lacking in resources, nor space. Economic activity is proportional to those acting within it.

For reference, the article does point out the following:

The United States said it was discussing with relief agencies how “safe areas” could be set up for civilians in Gaza. “One of the things that we did discuss with [Israel] was the need to protect civilian lives in Gaza, the need to establish some safe areas, where civilians could relocate to be safe from Israel’s legitimate security operations,” said a senior U.S. State Department official in briefing reporters. “So we’ve been engaged with the International Committee for the Red Cross, the UN relief agencies to work through the details of what that might look like. It’s still work that’s coming together. The Israelis are committed to it,” the official said.

The article also provides a map of the total evacuation area, which I assume was also provided to the Palestinians. Given that this evacuation area only applies to the north of the Gaza strip, I would assume that the evacuees could flee to the south. I’m not arguing that this is practical given the circumstances, but there technically are places to go.

Please correct me if there is extra information that would suggest that evacuation to the south is also not an option. There’s a lot of information out there regarding this situation, and I am not at all fully educated on the matter.

What is your rationale for making that statement?
