Assignment 1: Discussion—Biomes, Development, Pollution, and You Each part of the United States has at least one ecological crisis based on location, biome, and industrialization pattern. For example, the Midwest was once a prairie with very fertile soil. However, when people realized that with the right watering and drainage system this area could become productive farmland, there arose ecological problems. The conversion of the prairie to farmland is the root cause of many ecological problems in this region. Regardless of what biome you consider, humans have likely had an impact on the ecology of that area.

For this assignment, identify the biome in which you live. The following are a few examples of biomes: Tropical rainforests: This biome has high average temperatures, high moisture levels, and high species diversity. Prairies: The prairies have grassland-variable temperatures, variable moisture levels—depending on proximity to mountain ranges—and are mainly dominated by grasses and ungulate herbivores. Deserts: These biomes have hotter average temperatures, low moisture, lower species diversity, and a composition of species limited mainly to those that are adapted to hot temperatures. Temperate forests: The temperate forests have variable temperatures, high moisture levels, and higher species diversity. Taigas: These biomes have colder average temperatures, lower moisture levels, and lower species diversity. Tundras: The tundras have cold average temperatures, low moisture levels, and low species diversity. Coral reefs: These biomes have high average temperatures and high species diversity. Open oceans: These biomes have a wide range of temperatures and species diversity varies. Chaparrals: The chaparrals have higher average temperatures, lower moisture levels, and are dominated mainly by grasses and shrubs. Alpines: These biomes have low average temperatures, low precipitation, and receive high ultraviolet (UV) rays due to high elevation.

Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following: Explain how humans have impacted the biome in which you live. List the types of environmental damage that have been caused and the species that have been impacted. Describe the major pollution issues for your biome, and elaborate on the sources of this pollution. List any species that have become extinct in this biome. Support your statements with appropriate examples and scholarly references. Write your initial response in approximately 300–350 words. Apply APA standards to citation of sources. By Saturday, February 20, 2016, post your response to the appropriate Discussion Area. Through Wednesday, February 24, 2016, review and comment on at least two peers’ responses.

The biome I reside in is the temperate forest, characterized by variable temperatures, ample moisture, and high species diversity. Human activities have profoundly impacted this biome, leading to various environmental damages and pollution issues. Historically, human settlements, agriculture, and urbanization have resulted in deforestation, habitat fragmentation, and species displacement. These activities have significantly decreased biodiversity, threatening numerous native species.

Deforestation caused by logging, agriculture, and urban expansion has led to habitat loss for many species. For example, the eastern hemlock and the koala in Australia are threatened by habitat destruction associated with human encroachment. In temperate forests, mammals like the gray wolf and the red fox have experienced population declines due to hunting and habitat fragmentation. Bird species such as the wood thrush have also suffered declines because of habitat loss and pesticide use.

Pollution in temperate forests stems primarily from agricultural runoff, industrial emissions, vehicle exhaust, and waste disposal. These sources introduce pollutants such as nitrogen oxides, sulfur dioxide, pesticides, and heavy metals into the ecosystem. Acid rain, resulting from sulfur dioxide and nitrogen oxides emissions, significantly harms soil and water chemistry, affecting plant and aquatic life. Additionally, air pollution contributes to climate change, which further disrupts the ecological balance of the biome.

Species extinction within temperate forests includes the Carolina northern flying squirrel and the Saint Helena ebony tree. While some extinctions are documented, many species have declined sharply or are critically endangered without outright extinction. The loss of keystone species like the gray wolf has altered predator-prey dynamics, affecting overall ecological stability.

To counteract these impacts, environmental policies such as the Clean Air Act and the Endangered Species Act have been instrumental, but their enforcement and scope can be expanded. From an ecological perspective, laws should prioritize habitat conservation, sustainable forestry practices, and pollution control. Implementing stricter regulations on logging, industrial emissions, and agricultural runoff can help restore biodiversity and ecological balance. Promoting reforestation and protecting remaining habitat corridors are critical strategies for recovery. The introduction of incentives for sustainable land use and pollution mitigation can further support the health of temperate forests.
