This document discusses forests, deforestation, wildlife management, fisheries, and endangered species. It notes that forests are economically and ecologically important but deforestation is a major environmental concern. Deforestation is driven by wood usage, which is predicted to double by 2050, and paper production, which uses 30% of the world's paper despite only 5% of the population. Unsustainable logging and fishing practices have depleted fish and whale populations. International agreements have established protections and regulations for fisheries, whaling, and endangered species to curb overexploitation and prevent extinctions.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Landscapes
Forests are:
a. Economically important
1.
b. Ecologically important

2.
3.
4.
2. Deforestation
1. One of the most crucial environmental
concerns of our times
2. Direct causes
• a.
b.
c. in developing world = major
source of fuel
3. Case Study:
Paper and Deforestation
1. U.S. and paper:
a. We (5% or world’s pop.) use 30%
of paper

(upwelling, nutrients, algae)
Harmful commercial fishing techniques:
25. An estimated 2 billion hooks are set
each year by longline fishing fleets,
killing 40,000 sea turtles, over
300,000 sea birds and millions of
sharks annually, to name a few.
27. For every pound of shrimp caught,
10 - 20 lbs of bycatch “trawl
trash” is killed and discarded!
The area of the
seafloor trawled
is equal to 150X

forests clear cut
each year!

seafood.

c. __________________________established
in 1946 set moratorium on commercial whaling
in 1982 (very important!)
