How does water erosion affect humans? what are the short-term effects to humans? (property damage, contaminated water, damage to crops, etc.) what are the long-term effects to humans? (health issues, transportation difficulties, etc.)

For the answer to the question above for property damage, one example we could give is buildings or houses. Erosion decreases the value of this properties because the materials like metal are oxidizing and rust overtime and the structure's strength is decreasing over time. As for damage to crops. the land's nutrients decrease overtime too. Which means the crops can get fewer nutrients from the soil in order to perform Photosynthesis.

The long-term effects of this things on humans are things get riskier. Like a car. A 20-year-old car isn't the same as a brand new car in whatever ways. The brand new cars are safer because the materials that are used there are newer than the old car and they are more reliable. Same for humans. A 5-year old's health is not the same as a 50-year-old's health.
