I strongly recommend you to watch this! Health and climate are closely related. Walking, biking or running is beneficial for both yourself, your economy and the global climate!

I´m currently revising for my next final exam: energy and environment. There are several fascinating, worrying and interesting subjects brought back to my attention! Among them the effect food production has on the environment.
For my international readers, the bar graph is in Norwegian, but I´ll explain:
The image to the left is taken from one of our energy and environment-lectures. The bar graph gives an overview of the amount of CO2 emissions produced by various types of food. The scale is measured in grams CO2 equivalents per kg of the product. Not surprisingly, vegetables give very little emissions, while meat from cattle is by far worst. Cheese is the third worst, and vegetables grown in greenhouses give very high emissions compared to vegetables and fruit growing outside.

In short: a low-carb diet is disastrous for the environment. A varied, balanced diet with lots of vegetables is the key to sustainability!

Intelligent thermostat saves energy
Now here´s something I like! The intelligent thermostat Nest is just what we need to increase the efficiency in energy consumption. By automatic, flexible systems it´s easier to reduce the need of energy for heating and cooling buildings.
In a global scale, an automatic, easily operated thermostat controlling the temperature isingenious, just like the iPhone- generation would expect. The user-friendly and esthetic design is, by the way, designed by none other than Tony Fadell. He´s the mind behind Apple´s iPod and iPhone! If revolutionizing the music industry is possible within a few years, I feel pretty confident the same should be possible in the energy sector.
