The Future оf Dry Creek Wаtershed A rаpidly grоwing Texаs cоmmunity has expanded into a watershed that contains native grasslands, wetlands, and a small river known as Dry Creek. Over the past decade, population growth has increased demand for housing, roads, and commercial development. A local environmental science team collects the following observations: Wetland acreage has declined by 35% due to development. Fertilizer runoff from residential lawns has increased nitrogen and phosphorus levels in the creek. Algal blooms have become more frequent during summer months. Dissolved oxygen levels have decreased in several areas of the creek. Several native fish species have become less abundant. Community leaders are considering constructing a wastewater treatment facility to reduce nutrient pollution. Some residents argue that environmental regulations will slow economic growth. Scientists are conducting studies to determine the long-term effects of development on ecosystem health. 1. The environmental scientists investigating Dry Creek are using environmental science because they are examining: Scientists observe increasing nutrient concentrations, frequent algal blooms, and declining fish populations. Based on these observations, they propose that nutrient runoff is contributing to ecosystem degradation. 2. This conclusion is an example of: Some city officials argue that no action should be taken until scientists are completely certain that development is harming the creek ecosystem. 3. Which environmental principle would most strongly challenge this position? Scientists are concerned that nutrient pollution is altering the normal flow of energy through the Dry Creek ecosystem. 4. Which observation provides the strongest evidence that changes in photosynthetic organisms are contributing to broader ecological impacts? During a public meeting, one community member argues: "The wetlands should be protected even if their economic value cannot be measured because they are an important part of the natural community." 5. This viewpoint most closely reflects:
