How can the decision to build the Dakota Access Pipeline be described in terms of the three pillars of sustainability? The economic and environmental pillars aren't supported, but the social pillar is because the pipeline didn't jeopardize the cultural life of the Standing Rock Sioux. The environmental and social pillars aren't supported, but the economic pillar is because the oil being moved can support indefinite growth. The social pillar isn't supported, but the economic and environmental pillars are since additional studies showed the new path didn't put water resources or land at risk. The decision doesn't reflect sustainable development because none of the three pillars are supported
