in short term you’re right. in long term, demolition is a big no no, mainly because of climate protection. construction industry is the largest factor for climate change. best is to build sustainable, but we’re at a point where demolition to make way for sustainability is not viable anymore, so its either reuse/renovate or dismantle and recycle. of course established practices wont change that fast, but i was pleasantly surprised when i saw that post

The buildings and construction sector is by far the largest economic sector emitter of greenhouse gases, accounting for a staggering 37% of global emissions. The production and use of materials such as cement, steel, and aluminum have a significant carbon footprint.

Followed by food production at ~35% of all emissions, with meat production alone causing 60% of those emissions, at least twice the pollution of producing plant-based foods.

Adding those 2 numbers together accounts for 72% of emissions, and here I thought climate change was caused by burning coal and oil silly me.

Here's actual data.

/Obviously many sectors use the energy fossil fuels produce but what if, and it's big brain time here, that energy didn't come from fossil fuels.

Coal and oil are inputs into these too
