Scholars’ Circle – BBNJ Ocean Treaty to preserve Bio-diversity in the High Seas and Restoring ecosystem from invasive species – November 5, 2023

November 6, 2023 host

Biodiversity is under extreme attack in the high seas. With roughly 70% of the Earth’s surfaces as oceans, protecting biodiversity needed to extend beyond these national
jurisdictions. Hence, in June of this year, 2023, nearly 200 countries adopted the Biodiversity Beyond National Jurisdiction treaty, also called the BBNJ. we will explore what this treaty seeks to accomplish and what mechanisms are in place to protect ocean species. And we will examine the most significant risks to this biodiversity. [ dur: 28mins. ]

Invasive species are wreaking havoc all over the world and costing hundreds of billions of dollars per year. The alarming rate of the spread of invasive species are threatening nature, food security, our economies, and human health. Some areas are more successful than others in maintaining or restoring ecosystems with their indigenous species. How bad is the damage from invasive species and what can be done about it? We explore the south pacific island of New Zealand. [ dur: 28mins. ]

Scholars’ Circle – Wetlands Protection, the Clean Water Act and the US Supreme Court – July 2, 2023

July 3, 2023 host

In the wake of the US Supreme Court decision that weakened the EPA’s capacity to protect wetlands, we explore the role of wetlands in sustainability, biodiversity, and the economy. What might the decision mean for our environment, and economy? We examine Sackett vs. EPA, in a broader context what this means for the implementation of the Clean Water Act, what it means specifically for wetlands. What is the implication of framing the EPA as being against economic development?

What exactly does “waters of the United States” mean as discussed in this decision? [ dur: 58mins.]
