The Simple Genious of the Interstate Highway System (Video). Started by Dwight D. Eisenhower after WWII, it was an economic necessity and is considered to be one of the most influential infrastructures in the country (in US history). The project was achieved at a cost of $8.5M/mile (2016 dollars) to construct, which increased to $34M/mile in the 1980s (2016 dollars). Starting in 1956, it took nearly 40 years to complete the entire system. This reduced the 62-day journey from coast to coast to 42 hours.
The logistics of a nationwide transportation system is an engineering and economic marvel. On the other hand, there were some significant non-monetary and hidden costs. Check out this video for more details. (20-minute video, but worth the time – grab a coffee and enjoy).
The title of this 7-minute TEDEd video is “Can We Create the Perfect Farm?” As with a lot of future predictions, the techniques being proposed are already in production around the globe.
The video is correct – it will take global cooperative effort to succeed in adopting these practices as the norm, and it will also take consumer understanding and support of the agriculture industry’s efforts to be more sustainable and environmentally friendly while maintaining the production levels necessary to feed the world.
Contrary to pop-culture belief, the Agriculture industry is constantly looking for ways to improve – to use fewer resources, to produce a better product (grain, animals, etc.), and to be more efficient.
Ag Web has a terrific article about how farmers are using different ways to move toward carbon-neutral production; in this article, specifically livestock (pig, chicken, cow). The pork industry is looking toward a carbon-neutral pig by 2035 and the cattle industry is looking at 2050.
Pork production in the US contributes more than $23B to the economy, about 25% of which is exported and accounts for less than 1/2 of 1% of greenhouse gas emissions. Yet the pork industry continues to seek ways to improve efficiencies and reduce production resource needs.
It’s interesting to scroll down the list and see the progression of technology and how it invaded our lives and consciousness. Those of us who are (ahem) a bit older might recall living through these achievements.
NOTE the video below – in 1996, AT&T offered 5 hours of FREE internet every month.
Blast from the past – Check out this video to see the rise (and fall) of the most popular websites. What were the “Top 3” in 1993 versus the “Top 3” today? While the top website today won’t surprise you, the change over time is fascinating.
