Third, where risks are regional or global rather than local, many national governments, especially in poorer and smaller countries, may drag their heels in the hope that larger and richer countries will bear the costs of addressing them. Knowing this, larger and richer countries may be reluctant to take precautionary measures, as this would reward and thus encourage “free riding.”
第三，如果风险是地区性或者全球性的，而非地方性的，许多国家的政府、特别是小国和穷国可能会希望大国和富国将会支付解决问题的费用而拖延采取行动。大国和富国知道了这一点就会不愿意采取预防性措施，因为这样就会提供奖赏并鼓励“免费搭车”。
