Food Utilization

1. Despite recent evidence that higher atmospheric CO2 will tend to lower protein and micronutrient concentrations (see Chapter 7), there is much we don't know about the eventual health consequences of these changes. Will they be less or more important than associated changes in calorie consumption, and how do the two interact? What management options exist to minimize the reductions in protein or micronutrient levels in crops?

2. Climate change will very likely influence the exposure and infection rates for various human diseases, as discussed in Chapter 2. How will these changes aggravate, or be aggravated by, changes in food security? What are the critical links between disease and hunger and what are the best points of intervention to improve outcomes?

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
