    Sustainability in Canada

    Sustainability is the ability of the biosphere, or of a certain resource or practice, to persist in a state of balance over the long term. The concept of sustainability also includes things humans can do to preserve such a balance. Sustainable development, for instance, pairs such actions with growth. It aims to meet the needs of the present while ensuring that future people will be able to meet their needs.

    Sustainable Development

    Sustainable development has been defined by the United Nations (UN) as development that “meets the needs of the present” while ensuring the future sustainability of the planet, its people and its resources. Meeting these needs often requires balancing three key features of sustainable development: environmental protection, economic growth and social inclusion. The goals of sustainable development are interconnected. The most successful sustainable development projects will include environmental, economic and social considerations in their final plan. These considerations must include the free, prior and informed consent of any Indigenous groups impacted by a sustainable development project.
