In Week 3, we will have a more detailed look at the scientific evidence that human activities are influencing the Earth at the planetary level. You will be introduced to the concepts of Anthropocene and Planetary Boundaries. The biosphere (all living organisms or “biodiversity”) is arguably just as – or more – important than climate for establishing the environmental conditions we enjoy on Earth, but receives much less attention. Furthermore, we will be examining the mitigation and adaptive options, on the local and global scales, in response to reduced environmental sustainability. Additionally, we will look at the international agreements for climate change and how they seek to meet the goals of the SDGs. Using current global environmental challenges, we will discuss ways in which communities and societies have utilized indigenous knowledge, scientific evaluations, technological innovations, societal regulations and laws, environmental monitoring, and policy prescriptions in environmental management at various scales.
