The 50 million sheep of New Zealand outnumber its people 13 to 1, the highest such ratio in the world.
Topic
The wool industry in New Zealand
Framework
Problem/Solution
Main Point
Although the wool industry in NZ has been suffering since 1950, based on the rise of synthetic wool, it could improve its productivity by adopting the practices of the country's leading wool growers.
Summary
P1 - Intro / Description of Problem
After telling us about the glory days for NZ wool in the 1950's, we get a Purpose Pivot (but, yet, however, recently). It tells us about a drastic decline in profitability, so it looks like a good Framework could be Problem / Solution. The rest of the paragraph continues to unpack the problem.
P2 - Big Picture Solution
In this paragraph, the author rejects one Solution (raising wool prices) and says instead that we need to improve productivity, and "this goal could readily be achieved if" the NZ wool industry were to adopt the best practices of the leading wool growers.
P3 - Obstacle to Solution
This paragraph essentially continues its contention that better management could do the trick. A tension is introduced between "professional operations" (who are sympathetic to better management practices) and "family farmers" (who care more about lifestyle than maximal efficiency).
P4 - Specific Recommendation (start a genetic research company)
The author isn't talking about gene splicing, but rather just being more Darwinian by finding the superior sheep and keeping them as breeding stock.
