Energy sources unsuitable for mobile power plants, such as nuclear power, renewable hydroelectricity, or wind power can be used. According to widely accepted global energy reserve statistics, the reserves of liquid fuel are much less than gas and coal (at 42, 167 and 416 years respectively). Most countries with large rail networks do not have significant oil reserves and those that did, like the United States and Britain, have exhausted much of their reserves and have suffered declining oil output for decades. Therefore, there is also a strong economic incentive to substitute other fuels for oil. Rail electrification is often considered an important route towards consumption pattern reform. However, there are no reliable, peer-reviewed studies available to assist in rational public debate on this critical issue, although there are untranslated Soviet studies from the 1980s.

What is the recent incentive in order to overcome oil scarcity?
Answer: to substitute other fuels

In 2008 the Government of Canada made efforts, through the Canada First Defence Strategy, to modernize the Canadian Armed Forces, through the purchase of new equipment, improved training and readiness, as well as the establishment of the Canadian Special Operations Regiment. More funds were also put towards recruitment, which had been dwindling throughout the 1980s and '90s, possibly because the Canadian populace had come to perceive the CAF as peacekeepers rather than as soldiers, as shown in a 2008 survey conducted for the Department of National Defence. The poll found that nearly two thirds of Canadians agreed with the country's participation in the invasion of Afghanistan, and that the military should be stronger, but also that the purpose of the forces should be different, such as more focused on responding to natural disasters. Then CDS, Walter Natynczyk, said later that year that while recruiting has become more successful, the CF was facing a problem with its rate of loss of existing members, which increased between 2006 and 2008 from 6% to 9.2% annually.

What was the effort called to upgrade the Canadian Forces?
Answer: the Canada First Defence Strategy

As mentioned, lifestyle- and obesity-related diseases are becoming increasingly prevalent all around the world. There is little doubt that the increasingly widespread application of some modern food processing technologies has contributed to this development. The food processing industry is a major part of modern economy, and as such it is influential in political decisions (e.g., nutritional recommendations, agricultural subsidising). In any known profit-driven economy, health considerations are hardly a priority; effective production of cheap foods with a long shelf-life is more the trend. In general, whole, fresh foods have a relatively short shelf-life and are less profitable to produce and sell than are more processed foods. Thus, the consumer is left with the choice between more expensive, but nutritionally superior, whole, fresh foods, and cheap, usually nutritionally inferior, processed foods. Because processed foods are often cheaper, more convenient (in both purchasing, storage, and preparation), and more available, the consumption of nutritionally inferior foods has been increasing throughout the world along with many nutrition-related health complications.

Other than being cheaper, what is another main draw of processed foods?
Answer:
more convenient
