Economics, not philosophy, will end our oil dependence

We've known for decades that our dependence on Oil has a lot of downsides for us - pollution-producing extraction processes, Middle Eastern tyrants, risks of spills, the non-sustainable nature of oil stocks, etc. - and yet we've barely made a dent in changing over to alternative sources of energy. Even technologies like hybrid cars are merely more efficient, or trade off prices at the pump for prices at a central power plant. Philosophy and long-term self interest are not doing the job of moving us to a post-oil future.

What is? Simple economics. Pepsi has just announced a new plastic bottle produces NOT from oil, but from plant byproducts. And they didn't do it for philosophical reasons. They did it because PepsiCo produces hundreds of thousands of tons of plant waste every year on their food products, which they can reuse to produce packaging. Saving them millions.

The bottle is made from switch grass, pine bark, corn husks and other materials. Ultimately, Pepsi plans to also use orange peels, oat hulls, potato scraps and other leftovers from its food business.

The new bottle looks, feels and protects the drink inside exactly the same as its current bottles, said Rocco Papalia, senior vice president of advanced research at PepsiCo.

"It's a beautiful thing to behold," he said. "It's indistinguishable."

Cola Addicts Experience Weakness

During my weight-loss journey, one of the first things I did to cut calorie consumption was to cut out soda altogether. I like water and juices, so it has been easy to switch and it automatically has made every trip to a restaurant healthier by reducing the sugar intake. But a new study is showing that the only danger in cola is not sugar, but also a combination of problems which can lead to muscle weakness.

The first, a 21 year-old woman, was consuming up to three litres of cola a day and complained of fatigue, appetite loss and persistent vomiting. An electrocardiagram also revealed she had a heart blockage, while blood tests showed she had low potassium levels.
The second also had low potassium levels and was suffering from increasing muscular weakness. It turned out she had been drinking up to seven litres of cola a day for the last 10 months.
In a commentary on the paper, Dr Clifford Packer from the Louis Stokes Cleveland VA Medical Centre in Ohio relates the strange case of the ostrich farmer who returned from the Australian outback with muscle weakness. He had been drinking four litres of cola a day for the last three years and drank up to 10 litres a day when he was in the outback, causing a rapid reduction in his potassium levels.

I know several people who have switched from coffee to cola for their daily caffeine fix, because of the perception that it is healthier. I wonder how many of them are suffering from muscle weakness and have no idea that the cause is the fizzy drink in their hands.
