热带森林是地球上物种最丰富的生态系统。一些作者认为，根据对森林砍伐率的分析对热带森林灭绝危机的预测过于悲观，因为这些预测没有考虑到由于农村向城市迁移和随后的二次再生长而导致的未来农业废弃。即使出现这种再生长，也必须考虑与森林覆盖面积没有直接关系的物种所面临的威胁。狩猎是热带森林动物群消失的一个潜在但重要的驱动因素，有可能使森林植物和动物组成发生级联变化。无效的立法和执法沿着决策者未能解决狩猎的威胁，正在煽动热带森林灭绝危机的火焰。如果热带森林生态系统要生存下去，现在就必须充分解决不可持续的狩猎的威胁。
Tropical forests are among the most species‐rich ecosystems on the planet. Some authors argue that predictions of a tropical forest extinction crisis based on analyses of deforestation rates are overly pessimistic since they do not take account of future agricultural abandonment as a result of rural–urban migration and subsequent secondary regrowth. Even if such regrowth occurs, it is crucial to consider threats to species that are not directly correlated with area of forest cover. Hunting is an insidious but significant driver of tropical forest defaunation, risking cascading changes in forest plant and animal composition. Ineffective legislation and enforcement along with a failure of decision makers to address the threats of hunting is fanning the fire of a tropical forest extinction crisis. If tropical forest ecosystems are to survive, the threat of unsustainable hunting must be adequately addressed now.
