These changing wants encourage producers to manufacture new and better products. However, since resources such as land, labour, capital and time are limited, it is impossible to satisfy every human want. Therefore, every individual, business and government must make choices while using available resources. This reflects the chapter&rsquo;s core idea that unlimited wants must be managed through efficient use of limited resources.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\">\n\n\n\n<h1 class=\"wp-block-heading\">Question 2<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>&lsquo;Human wants are unlimited and keep changing.&rsquo; How do you think this constant desire for more creates pressure on the environment?
