"Canada's prime minister, Stephen Harper, faces a widening revolt by the country's leading scientists against sweeping cuts to government research labs and broadly pro-industry policies.
The scientists plan to march through Ottawa in white lab coats on Tuesday in the second big protest in a month against the Harper government's science and environmental agenda.
Harper is accused of pushing through a slew of policies weakening or abolishing environmental protections – with an aim of expanding development of natural resources such as the Alberta tar sands."
