Final answer:
The resource issue in South Asia that should receive the most funding and attention is environmental degradation.
Step-by-step explanation:
The resource issue in South Asia that should receive the most funding and attention is environmental degradation. Due to population growth and resource depletion, countries like India are struggling with major environmental problems such as water pollution, air pollution, and deforestation. These issues have severe consequences on the health and well-being of the population, as well as the sustainability of the region's natural resources.
By focusing on environmental degradation, funding and attention can be directed towards implementing sustainable practices, improving waste management systems, promoting renewable energy sources, and conserving biodiversity. Addressing these resource issues will not only benefit the environment but also the overall quality of life for the people in South Asia.
