To determine which strategy will most decrease the number of people sickened by water-borne diseases, we need to evaluate each option and consider their potential impacts.

1. Increased use of solar power: Although solar power has numerous benefits for energy production, it may not directly address the issue of water-borne diseases. Solar power primarily focuses on sustainable energy generation and reducing carbon emissions, which can indirectly contribute to environmental improvements. However, it may not directly reduce the risk of water contamination.

2. Increased use of fungicides: Fungicides are primarily used to control or eliminate fungal infections in agriculture. While they may help improve agricultural yields, they have limited impact on water-borne diseases. Water-borne diseases are typically caused by pathogens like bacteria, viruses, and parasites, rather than fungi.

3. Improved agriculture: This option could have some positive effects on reducing water-borne diseases. Improved agricultural practices can include proper water management, avoiding excessive use of fertilizers and pesticides, and promoting crop diversification. These measures can minimize the runoff of contaminants into water sources, thus decreasing the risk of water contamination.

4. Better sanitation systems: This strategy has the most direct impact on reducing water-borne diseases. Proper sanitation systems, including safe waste disposal and clean water supply, play a crucial role in preventing the transmission of water-borne pathogens. Access to improved sanitation facilities and practices significantly reduces the risk of water contamination and the spread of water-borne diseases.

Considering the options, it is clear that option 4, better sanitation systems, would have the most significant effect in decreasing the number of people sickened by water-borne diseases. Implementing and improving sanitation infrastructure, providing clean water supply, and ensuring proper waste disposal are fundamental measures to prevent water-borne illnesses.
