Final answer:
Wealthy nations ensure access to clean water through infrastructure, while poorer nations face challenges due to limited funds. Overcoming barriers is crucial for achieving water sustainability and ensuring safe drinking water for all.
Explanation:
Wealthier nations address water problems by building infrastructure like deep wells and large dams, ensuring most have access to clean water. In contrast, poorer nations struggle due to lack of funds, leading to challenges in developing water supplies.
The global community faces issues in water sustainability, requiring solutions like 'more crop for the drop' and 'virtual water' to feed more people with less water. It is essential to overcome social, political, and economic barriers to ensure everyone has access to safe drinking water.
The debate on whether water is a human right is ongoing, with differing opinions on privatization versus recognizing water and sanitation as human rights by international bodies like the United Nations General Assembly.
