Can we do things better with wood?

Image
As the climate crisis grows more severe, some are suggesting the use of prefabricated structural wood components in place of concrete and steel for support in large buildings. Yes, wood structures mean the cutting of trees. But the overall climate impact may be substantially less than the immense carbon footprint of concrete and steel construction. Michael Green, an architect who is a proponent of wood construction notes that, “Roughly 11 percent of the global carbon footprint is related to what buildings are made out of.” FOR THE WHOLE STORY ==> https://www.nytimes.com/2019/11/20/style/engineered-wood-tower-construction.html [ Photo: P.

Round trees in square holes

Image
Ever plant stuff? I do. And I always dig a round hole to put the transplant it. Well, approximately round anyway. Who doesn't? Lots of people planting trees these days. And apparently some of them have been doing it wrong. Apparently when planted in a round hole there is a big chance that the roots will grow in a circular pattern and not expand out to provide a healthy support pattern. The solution to growing more resilient trees? Why plant round trees in square holes of course!

Curbing Noise Pollution with Trees

Image
  "Research is proving the effectiveness of trees and shrubs as noise abaters—research prompted by the growing awareness that excessive noise is a form of environmental pollution. The average community noise level has risen fourfold in the past 20 years with jet aircraft, the heavy vehicular traffic, and domestic power equipment contributing to the problem. It is likely to go higher if it is not checked." But how many trees does one need? It turns out the that number and types of trees and shrubs is important in creating an effective noise filter. "In some situations trees will reduce noise levels up to 50% but to be effective you need a tree barrier that is at least 50 feet deep. It also needs to be longer than you might expect, and it needs to consist of both trees and shrubs that start at ground level." And, "evergreens are favored for year-round noise screening. " For additional reading on the subject: Trees And Shrubs Can Curb Noi...
