Assignment 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 this assignment, identify the biome in which you live and explain how humans have impacted it. List the types of environmental damage caused and 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.

Understanding Biomes and Human Impact

The biome I live in is the temperate forest biome, which experiences variable temperatures throughout the year and receives abundant moisture, making it an ecosystem rich in biodiversity. This area supports various plant and animal species, serving as a critical habitat. However, human activities have drastically altered this biome, as industrialization and urban development have emerged as significant contributors to environmental degradation.

Human Impacts on the Temperate Forest Biome

Human impact on temperate forests can be categorized into several key areas, including deforestation, urban sprawl, agriculture, and pollution. Deforestation is perhaps the most visible impact, where large areas of forest are cleared for timber or to make way for agricultural land. As mentioned by Foster et al. (2020), conversion of these ecosystems disrupts habitats and leads to a decline in biodiversity.

Urban sprawl has introduced impervious surfaces to the biome, which has altered natural water drainage patterns, contributing to increased flooding and erosion (McMahon et al., 2018). Additionally, agricultural practices have led to soil compaction, nutrient depletion, and increased runoff of fertilizers and pesticides into nearby water bodies, resulting in water quality degradation.

Types of Environmental Damage

Environmental damage in the temperate forest biome includes habitat loss, fragmentation, and pollution. Habitat loss due to deforestation has resulted in a decline in species populations, including the Eastern cougar (Puma concolor couguar), which has faced extinction largely due to habitat fragmentation and loss (Raine, 2021). Fragmentation leads to isolated populations that struggle to thrive, impacting genetic diversity.

Major Pollution Issues in the Biome

Pollution has become a critical concern for the temperate forest biome. Air pollution from transportation and industrial sources introduces harmful substances into the atmosphere, leading to acid rain, which negatively affects plant life and soil chemistry (Norton et al., 2019). Water pollution is another significant challenge, with runoff from agricultural lands washing pesticides and fertilizers into local rivers and streams, leading to harmful algal blooms that deplete oxygen and pose threats to aquatic life.

The improper disposal of waste and industrial chemicals also contaminates soil and waterways, causing long-term ecological harm. As noted by Smith et al. (2022), heavy metals and other toxic pollutants accumulate within the ecosystem, affecting species health and survival. Species such as the Eastern brook trout (Salvelinus fontinalis) have shown declining populations due to increased pollution levels in aquatic habitats.

Species Extinction in the Temperate Forest Biome

Sadly, the temperate forest biome has lost several species to extinction. One notable example is the passenger pigeon (Ectopistes migratorius), which once thrived in these ecosystems but faced drastic population declines due to overhunting and habitat destruction in the early 20th century (Kindred, 2021). This serves as a cautionary tale of the consequences of unchecked human expansion and exploitation of natural resources.

Conclusion

The transforming impact of human activities on the temperate forest biome is substantial, with ongoing issues of habitat destruction, pollution, and species extinction. While there are steps that can be taken to mitigate these impacts, it is crucial to cultivate a greater awareness and commitment to sustainable practices to preserve the ecological balance. By thinking globally yet acting locally, we can contribute positively to our environment and curtail further degradation of this vital biome.
