Working toward a healthy and sustainable diet

wpid-20150112_151027.jpgIn a recent review in the journal, Frontiers in Nutrition, Ruini et al. state that there is a

“strong correlation between the environmental impact of food and their nutritional characteristics. Specifically, it has been demonstrated that the foods whose consumption should be moderated for health reasons are also those that have a greater impact in terms of soil use, water consumption, and CO2 emission. In other words, to achieve a sustainable, healthy diet is essential to eat more plant-based foods and reduce our consumption of meat, animal products, and other foods, like salted snacks and sweets, which offer little in terms of nutritional value.”

An important observation.  It would appear that a plant-based diet is better for our health, more environmentally friendly and cost-effective. Reminds me of that quote that we are sometimes surrounded by solutions rather than problems!

It looks like Apple is building a car.

In an article in MacWorld (1), Elon Musk was quoted as saying that Apples Project Titan was an “open secret … It’s pretty hard to hide something if you hire over a thousand engineers to do it.”

Personally, I believe that environmentally friendly, point to point transport, will be the future of modern transit systems.  This is not to say that mass transit systems do not have a role. We just need to keep in mind their practical limitations. Ever tried to do the family shopping by train?

China closing coal mines in its own country and mining the Liverpool Plains


The state government has approved the Shenhua coal mine in the Liverpool Plains, which is perhaps the most productive agricultural land in the country (1). At the same time, the Chinese government plans to halt coal mining approvals in its country and close a thousand mines that are already in production (2).  Bob Hawkes 1988 wish that we should become a clever country has clearly not eventuated (3).

Green space, urbanity, and health: how strong is the relation?

“This research shows that the percentage of green space in people’s living environment has a positive association with the perceived general health of residents. Green space seems to be more than just a luxury … ” (See Link)
