The tar sands production is damaging the environment and animal habitats in several ways. It is destroying the boreal forest habitat, which nearly 50% of bird species in North America rely on. Production is also poisoning waterways and the air, causing declines in species near operations and increased rates of cancer in nearby communities. Approximately 1 million cubic meters of water per day is diverted from the Athabasca River for tar sands operations, with 92% ending up in tailing ponds and contaminating downstream areas. The tar sands are also the fastest growing source of greenhouse gases in Canada.
