Dozens of people have been arrested near Vancouver, Canada, in a blockade against test drilling for an extended oil pipeline. Protesters have camped out on Burnaby Mountain to stop the company Kinder Morgan’s plans to expand its Trans Mountain pipeline, which brings tar sands oil from Alberta to Canada’s west coast. Protester Tamo Campos spoke out after his arrest.

Tamo Campos: “Why are we putting our economic system, the market, above the very ecology that we all depend upon? We’re more dependent on clean water, fresh air and clean soil than the market. It’s the thing that keeps us alive. And we have to stand up to unjust laws, to make those the laws, because those are the laws that have always governed our lives. And indigenous people have had natural laws that predate colonial laws by thousands of years, and we need to respect that.”

Campos is the grandson of the prominent Canadian environmentalist David Suzuki. An 11-year-old girl was also among those detained on Sunday.
