Ed Struzik: “The challenges of restoring a landscape uprooted by the destructive practice of oil sands mining — which involves strip mining the earth to depths of up to 250 feet — are enormous. Oil sands mining occurs primarily in complex wetland ecosystems of boreal swamps, bogs, and peatland fens that were formed over thousands of years and harbor a significant amount of biodiversity. Many experts doubt whether it’s technically or even economically possible to recreate on a large scale anything resembling the sensitive environments that existed there in the past. Even if were possible, others wonder whether climate change and rapidly expanding tar sands development in Canada — the volume of tar sands mining is expected to nearly double by 2021 — will sabotage efforts to accomplish this on a broad scale in the future.”
