Debate
Debate
We will have a short debate with 2 teams defending the neo-Malthusian and anti-Malthusian theories.
- 3 people will speak on each team
- Prepare opening statements for your perspective
- The rest of the class will comment on the debate using backchannelchat.com
Resource stewardship strategies, including:
Resource stewardship strategies, including:
- the value of the circular economy as a systems approach for effective cycling of materials and energy
- the role of the UN Sustainable Development Goals and progress made toward meeting them
This is a fitting final section for the core of the DP course since it focuses on the interconnectedness of most, if not all, of the issues we have discussed in the course: You can apply all of these issues to the idea of a multi-faceted solution, where each part has a direct impact on the others, and is indispensable to the whole.
The Circular economy
The Circular economy
"A framework for an economy that is restorative and regenerative by design" to go from linear to circular, like an ecosystem
"A framework for an economy that is restorative and regenerative by design" to go from linear to circular, like an ecosystem
The circular economy must be addressed at a variety of scales, from local to global, and from small businesses to TNCs

- Keep products and materials in use
- Regenerate natural systems

The role of the UN Sustainable Development Goals and progress made toward meeting them (continued)
The role of the UN Sustainable Development Goals and progress made toward meeting them (continued)
Goal 12: Ensure sustainable consumption and production patterns
Goal 12: Ensure sustainable consumption and production patterns
"Decoupling economic growth from resource use is one of the most critical and complex challenges facing humanity today. Doing so effectively will require policies that create a conducive environment for such change, social and physical infrastructure and markets, and a profound transformation of business practices along global value chains."
- 12.3 - By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses
- 12.4 - By 2020, achieve the environmentally sound management of chemicals and all wastes throughout their life cycle
- 12.5 - By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse
Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all
Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all
"Ensuring access to affordable, reliable and modern energy for all has come one step closer due to recent progress in electrification, particularly in LDCs, and improvements in industrial energy efficiency. However, national priorities and policy ambitions still need to be strengthened to put the world on track to meet the energy targets for 2030"
- 7.1 - By 2030, ensure universal access to affordable, reliable and modern energy services
- 7.2 - By 2030, increase substantially the share of renewable energy in the global energy mix
- 7.A - By 2030, enhance international cooperation to facilitate access to clean energy research and technology
