Biodiversity is a huge factor when considering the health of an ecosystem, a community of living organisms, and the physical environment they are dependent upon (Sayre 15). Land, water, air, and even noise pollution can make a habitat unlivable for birds and other wildlife (Sayre 2). Birds are a very important part of the national food web (Sayre 16).
