Does the real estate market increasingly force more families to build?

What was specifically claimed? Whether that is wrong or right, I will judge for myself.

Just watch the mentioned video or don't, if you prefer. If some left-green demonstrators think that CO2 is harmful to trees, that the production of the electric car battery is so much more environmentally friendly, or that the economic prosperity of an industrialized country and the supply of 82 million people can also be climate-neutral, then I gladly stand on the side of those who are accused of spreading only falsehoods or questioning 150 years of physics.

she cannot communicate her demands and foresight with people who, for example, work at RWE in the lignite industry.

As if that were originally her task. She is a figurehead, a face. If the movement is serious, someone else can do that.
I still see the disqualification of all other participants because of the illness of the pioneer, and it is still disingenuous.
Do you want to express that the movement as a whole is nonsensical because Thunberg cannot differentiate? Or would the cause be better if demonstrations were held on Saturdays? For your standards, you are surprisingly vague and only point fingers.

Whoever distills gasoline automatically gets diesel and heavy oils as leftovers. If you are not allowed to use that now, then what should be done with it? Ships consume heavy oil. Conclusion: Think before swinging the legislative hammer. There is no life with a clean slate. K.

Heavy oil can be further refined, desulfurized (hydrodesulfurization), etc. But no one does that because burning it at sea is cheaper. Even filters would help, but why should anyone spend money on that? Only government intervention could bring about an improvement here. Correction: enforce it.

You can't refuse anyone basic security if Art.1 of the GG is to apply...

Thank you for the reminder of the inviolability of human dignity. That provides orientation.

and the other "Asperger" debaters here:
Autistic people usually have extraordinary abilities. It shows a high level of ignorance to call their statements into question in a discrediting and discriminatory manner based on a diagnosis. The opposite is effective: listen, appreciate, and want to understand.

It is good when the world listens to Ms. Thunberg and lets her have a voice. It is good when students begin to engage again. Are there some among them who enjoy the event character and skipping school? Certainly. That is also good, because every movement needs followers to gain strength – for better or worse.

Regarding the initial question:
No, no family is "forced" by the real estate market to build a house. The feeling of "coercion" stems from a discrepancy between market conditions, income situation, and one's own expectations.

If any left-green demonstrators think that CO2 is harmful to trees, that the production of the battery of the electric car is so much more environmentally friendly, or that the economic prosperity of an industrialized country and the supply of 82 million people can also be climate-neutral

That is indeed all nonsense. However, I can conduct individual interviews at any gathering of enough people in which nonsense is spoken. In the end, I then edit the collected nonsense one after the other and tadaa... I meant something else: There are parts of the AfD that misuse the temperature data by using unscientific methods to "subtract" the warming of the last century in order to then say: It doesn't exist at all! (Fake news approach). Then there is a very small part that even declares the physical principle of the greenhouse effect itself (known for 150 years) to be nonsense. And they go canvassing for votes in a not-so-small camp where people consider climate change to be an invented instrument of domination. But that obviously has nothing to do with the video.

In the end, I splice together all the collected nonsense one after the other and tadaa…

Alone, just what would already be gathered here in the forum...
