When companies use resources to create goods and services for consumers,they are generally not reguired to pay the environmental costs of such resource use.For example,fishing companies pay the costs of catching fish but do not pay for the depletion of fish stocks.timber companies pay for clear-cutting for ests but not for the resulting environ mental degradation and loss of wildlife habitat.these companies reasonably seek to maximize their profits,so they do not voluntarily pay these costs or even try to assess them,unless reguired to do so by government laws or regulations.
當公司使用資源創造貨物和給消費者服務時,它們不會要求去支付使用資源的環境代價.例如:捕魚公司支付捕魚的費用但是不會支付魚類.木材公司適合清楚砍森林支付但不是一個導致環境墮落和野生動物棲息地損失.這些公司合理想辦法使他們的益處最大化,因此他們不自願支付這些費用或者甚至努力評價它們,除非要求以政府法律或者規章來做.
