Could we build a wooden skyscraper?

Summary

Mjøstårnet is the world's tallest wooden building made almost entirely from the trees of neighboring forests in the Norwegian countryside. It　was built in 2019, it started with the invention of glue-laminated timber called glulam, and engineers developed cross-laminated timber called  CLT to battle powerful winds.

In fact, the timber can be shaped quickly using computer directed cutting machines, 

engineered wood can be prefabricated in a factory, and

it’s biodegradable materials thus less waste.

By earthquake and fire, cracked wood panels can be easily replaced, and the CLT gives enough time to evacuate from fires. 

The timber is a renewable resource, and 

it is easier to heat and cool buildings with less energy waste.

It couldn’t be told that CLT is not strong enough to support a 40-story building and requires vastly more lumber than traditional wooden construction, though, even if only buildings under 30 stories were built from wood, it would reduce the carbon footprint of those structures by more than 25%.

We have to know about technological advancement to protect our earth.
