Perhaps the most important, cross-cutting problem is poverty, which afflicts billions of people and underlies most other development problems. When you are poor, your children will more likely suffer malnutrition and succumb to TB.
或许最重要的跨领域问题是贫困，令数十亿人深受其害并构成其他多数发展问题的罪魁祸首。如果你是穷人，你的孩子更容易营养不良及患上结核病。如果你是穷人，你更有可能砍伐并烧毁热带雨林或者为了捕鱼在珊瑚礁上使用炸药。
