Statistics Canada's first survey of urban green space shows that cities across the country are getting greyer and browner.
Statistics Canada's first survey of urban green space shows that, just as the singer-songwriter warned, cities across the country are getting greyer and browner.
"We did a see a decrease over the time period we looked at," said Jennie Wang, who helped prepare a massive report from the federal agency released this month on human activity and the environment.
StatCan used satellite imagery to estimate the amount of green space in Canadian cities -- parks, urban trees, even backyards and lawns. The data has existed for years, but it was used for this purpose.
"(We're) getting a sense of the condition of vegetation in urban areas," Wang said. "It's the first time we've done that."
