Unfortunately, you can’t just put plants everywhere. CO2 conversion is also highly dependent on light levels, which sufficient light levels not being achievable everywhere.

Office buildings with a large number of people meeting rooms etc.) could also benefit from monitoring.

Heck, even at home, I have a room that quickly accumulates CO2, easily reaching 2000ppm with just a single person being inside, which makes spending prolonged time in said room a tiring affair.

By that logic, the best thing to do for the environment is to die - which is probably true, it’s just not a very good (or even particularly interesting) argument.

No, it’s not. Lego has been bullying local distributors of other brick systems (e. g. CADA) by issuing patent claims, knowing very very well that those claims are false and the patents have expired long ago.

However, customs has to hold and store the shipping containers until the court settles, and they charge for it. A lot. This forces small shops (down to your local mom&pop toy store) to pay for customs storage fees, for weeks, sometimes months. These costs are high enough to force small shops out of business, mind you.

Along with the declining quality of the sets and the increasing cost, Lego is very well a shitty company.
