Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction. For example, if a population is exposed to a new disease, selection will act on genes for resistance to the disease if they exist in the population.
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.
