In-Depth Notes on Environmentalism and Genetic Engineering

Death of the Pope
  • Unexpected news of the pope's death, particularly touching for many, especially for those connected to indigenous groups and populations, and notably for the Argentine community.
  • Importance of observing the subsequent three weeks post-announcement for insights and reactions.
Environmental Movement
  • Key figures mentioned include:
    • John Muir: Environmentalist from California known for his advocacy for the preservation of wilderness.
    • Rachel Carson: Worked for the Department of Agriculture, significant for her environmental activism.
    • Henry David Thoreau: Influential philosopher and naturalist from Massachusetts, noted for his work related to nature and social critique.
  • Environmental movement arises not just from individual efforts, but as a collective political and social initiative.
The Amazon Rainforest
  • The Amazon, referred to as the world’s largest rainforest, accounts for one-fifth of the world's fresh water supply.
  • It faces significant challenges, including species extinction and habitat loss due to human activities.
  • The discussion raises questions about animal reintroduction, especially regarding extinct species like the dire wolf.
Genetic Engineering and De-extinction
  • Recent advancements leading to the creation of hybrid "dire wolves" by editing the genome of living wolves using ancient DNA techniques.
    • Scientists extracted DNA from 72,000-year-old inner ear bone and a 13,000-year-old tooth of a dire wolf to sequence its genome.
    • Utilized CRISPR technology to edit 14 genes at 20 sites in a grey wolf’s genome.
    • Resulted in the birth of three wolf pups through surrogate domestic dogs.
  • Important to note:
    • The creations are not exact replicas of the dire wolf due to the incompleteness of ancient genomes; they are hybrids.
    • The concept of “de-extinction” is complex and involves discussions on genetic fidelity versus engineered resemblance to extinct species.
Environmental Challenges
  • Discussion of the socio-economic pressures faced by countries bordering the Amazon, many struggling with debts from international financial institutions like the IMF and World Bank.
  • Critical environmental issues linked to the extraction of resources and encroachment on natural habitats.
The Issue of Climate Change
  • Recognized as a wicked problem due to its complexity involving many interconnected factors.
  • Historical reference to the environmental impact of CFCs and actions taken to abolish them, highlighting the importance of global cooperation in addressing environmental crises.
  • Methane as a significant greenhouse gas, particularly from melting permafrost, raising alarm on emissions.
Climate Refugees
  • Concept of climate refugees discussed in relation to geographical vulnerabilities, especially in places like Southern Louisiana and the Bahamas, which are at risk from rising sea levels and climate change impacts.
  • Trinidad and Tobago identified as having the highest risk in the Caribbean Basin due to low lying geography.
Conclusion
  • The upcoming class will have a shorter schedule, with anticipation for student presentations. Discussion topics will likely remain centered around environmental issues and the implications of genetic engineering in wildlife conservation.
