A Renaissance for Wood?
A new study in the journal Carbon Management says architects should consider more wooden structures to reduce carbon emissions and create valuable carbon storehouses.
What's the Latest Development?
If architects designed more buildings from wood, less carbon would be emitted during the construction process and wooden buildings would store excess carbon currently hanging in the atmosphere. University of Washington professor Bruce Lippke, author of new paper published in the journal Carbon Management, says: "Every time you see a wood building, it's a storehouse of carbon from the forest. When you see steel or concrete, you're seeing the emissions of carbon dioxide that had to go into the atmosphere for those structures to go up."
What's the Big Idea?
Would a new generation of wooden buildings require forests to be cleared, forests which are more valuable as carbon storehouses than in their processes form as wooden beams? No, says Lippke: "While the carbon in the wood stored in forests is substantial, like any garden, forests have limited capacity to absorb carbon from the atmosphere as they age. ... However, like harvesting a garden sustainably, we can use the wood grown in our forests for products and biofuels to displace the use of fossil-intensive products and fuels like steel, concrete, coal and oil."
Are university safe spaces killing intellectual growth?
Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
