Final answer:
The cycles of poverty and development work against sustainable development by perpetuating underdevelopment and environmental degradation.
Step-by-step explanation:
Sustainable development is hindered by the two cycles of poverty and development. The cycle of poverty perpetuates underdevelopment, as individuals face limited access to education, healthcare, and essential services. This lack of investment further exacerbates poverty, creating a self-perpetuating cycle. On the other hand, the cycle of development often leads to exploitation of resources, environmental degradation, and inequality. It is important to find a balance between economic growth and environmental conservation to ensure sustainable development.
