The hemp fields sprouting in a part of Canada best known for its giant oil patch show how climate change is disrupting the construction industry.
Six years after setting up shop in the shadow of Calgarys oil patch, Mac Radford, 64, says he cant satisfy all the orders from builders for Earth-friendly materials that help them limit their carbon footprints. His company, JustBioFiber Structural Solutions, is on the vanguard of businesses using hemp the boring cousin of marijuana devoid of psychoactive content to mitigate the greenhouse gases behind global warming.

Roman engineers used the plants sinewy fibers in the mortar they mixed to hold up bridges.
