求翻译：发展中国家应制定长远的能保证经济可持续发展的战略，不要为了短期利益而牺牲长期发展前景，而发达国家更应为全球环境的维护和改善承担更多责任。是什么意思？

Developing countries should develop a long term to ensure sustainable economic development strategy, not to short-term interests at the expense of long-term development prospects, while developed countries should take more responsibility for the global environment to maintain and improve.
