What aspect does the Brundtland Commission's work primarily focus on?

The Brundtland Commission, formally known as the World Commission on Environment and Development, primarily focuses on environmental sustainability. This commission, established by the United Nations in 1983, aimed to address the challenges of sustainable development. Its landmark report, "Our Common Future," articulated the concept of sustainable development, emphasizing the interdependence of environmental, social, and economic factors.

Environmental sustainability is at the core of the commission's work as it seeks to reconcile the needs of the present without compromising the ability of future generations to meet their own needs. The report highlighted the importance of protecting the environment through responsible management of resources, ensuring that development is both economically beneficial and environmentally sound.

In the context of the other options, while technological advancements, global economic strategy, and healthcare reform are important topics, they are not the primary focus of the Brundtland Commission. Rather, the commission advocates for a holistic view that integrates these aspects within the broader framework of sustainable development, but its central message remains rooted in the principles of environmental sustainability.
