1. "When in a sour mood, stop everything and ask if you are in need of food, sleep, a potty break, fresh air, or exercise." From Justin Wehr via Ben Casnocha. I agree, but would point out that if you're getting upset because you're hungry, it's probably because your body is addicted to sugar and carbs.
2. Government panel of experts releasing new health guidelines and updating the USDA Food Pyramid. Get this:
"Congress mandates that the guidelines be revised every five years."
Is this revision going to go on indefinitely, or at some point are we going to know what's good for us? What happens when the foundation of the food pyramid, grain consumption, crumbles? Does the whole structure collapse? Don't get your health information from the government, they don't have the incentives or the knowledge to get it right.
3. Is ecological (i.e., organic) agriculture productive? This research says yes.
"A variety of resource conserving technologies and practices were used, including integrated pest management, integrated nutrient management, conservation tillage, agroforestry, water harvesting in dryland areas, and livestock and aquaculture integration into farming systems."
We should see these agricultural practices as entrepreneurial innovations, not Luddite alternatives to modern farming. The problem with research like this is that they always embed broader environmental values into their conclusions that don't always relate to to how well we can feed people over the long run (including direct environmental effects that affect our ability to do so).
"These practices not only increased yields, but also reduced adverse effects on the environment and contributed to important environmental goods and services (e.g., climate change mitigation), as evidenced by increased water use efficiency and carbon sequestration, and reduced pesticide use."
The relationship between these agricultural methods, global warming, and long term agricultural productivity is so complex that it would be better to treat separately and just focus on yields. There's also the inconvenient truth that plants love CO2, and they thrive in environments where CO2 levels are high.
