Biomes And Ecosystems Questions Medium
The major threats to tundra ecosystems include climate change, oil and gas exploration and extraction, pollution, invasive species, and human activities such as mining, infrastructure development, and overgrazing. Climate change is a significant threat as it leads to rising temperatures, melting permafrost, and changes in precipitation patterns, which can disrupt the delicate balance of the tundra ecosystem. Oil and gas exploration and extraction can cause habitat destruction, pollution, and disturbance to wildlife. Pollution from industrial activities and human settlements can contaminate water and soil, affecting the health of plants and animals. Invasive species, introduced by human activities, can outcompete native species and disrupt the natural ecosystem dynamics. Human activities such as mining and infrastructure development can lead to habitat destruction and fragmentation, further impacting the tundra ecosystem. Overgrazing by domesticated animals can also degrade the vegetation and soil, affecting the overall health of the ecosystem.
