"For one cause or another, it has become necessary to impose restrictions upon the use of many commodities, including not a few of the necessities of life"

This quote by William Lyon Mackenzie King speaks to the need for limitations on making use of numerous products, including a few of the most necessary products for life. This implies that, for whatever factor, it has actually become necessary to restrict the use of these products. This could be due to a shortage of resources, a need to conserve, or a desire to secure the environment. It could also be due to financial or political reasons, such as a desire to control prices or to protect particular markets. Whatever the cause, it is clear that limitations are essential in order to guarantee that these items are used responsibly and sustainably. This quote functions as a suggestion that, even in times of abundance, it is important to be mindful of our consumption and to use resources wisely.
