Today in our environmental science lecture, we're discussing the impact of urban development on local ecosystems. One key example is the construction of a new highway near the town of Greenfield. Before the highway was built in 2018, the area was home to over 200 species of birds. However, a recent survey conducted last year found that this number has dropped to just 150. Additionally, noise pollution has increased significantly, affecting the breeding patterns of native frogs. Interestingly, the local council has now proposed a wildlife corridor to connect fragmented habitats, which could help restore some of the lost biodiversity.
