I think that carbon dioxide can be transformed by plants, but I don't know how many plants are needed to make this process stable.
The process was stable for thousands of years until humans started using large amounts of fossil fuels and reintroducing millions of tons of carbon which had been sequestered from the cycle.

Have you read any research on the effect of CO2 concentration on plants?
It can increase the growth of plants to a certain degree but where all other variables are the same. The increase in CO2 in the atmosphere increases the heat levels which in turn impacts precipitation patterns and negatively impacts plant growth.

Can plants or anyone else use atmospheric methane?
It naturally degrades into CO2 over time.

... I prefer wood whenever possible given that it is easy to work and is renewable, but there are applications that stone works better, such as retaining walls.
I also like working with wood. In the future, I plan to make a wood dryer, because it is difficult to find well-prepared wood.
I had a friend who years ago cut and milled lumber to build his house, but the wood all warped horribly in the drying process. He wasted all of that effort to wind up with essentially firewood.

Sometimes I read that aerated concrete is a new ecological material. But in practice it is difficult to use, it requires a good basis to prevent deformation and cracking. We have a very deep frost of ground, sometimes the groundwater level is very high, both reasons require that the base be deeper.
Yes, where I grew up had a much lower frostline than where I live now. It is hard to explain to people why I automatically view footers as being too shallow.

This winter is very snowy. But I already forgot when there were real frosts. Today -12 C (10 F), but when I was at school, I remember low temperatures of -25 ...- 30 C (-13 ...- 22 F).
We have similar temperatures here this morning with wind chill in the lower single digits F.

What type of internet is commonly used in the US to connect? I mean for distant places.
The local areas have different service providers with different connection methods. Cable is popular in most places, but some lin remote areas have satellite connection. I have fiber optic here. I believe most of the major connections are now fiber optic, but I am not sure.
