The Species Approach Chapter 9 Core Case Study The Passenger Pigeon Gone Forever Once the most numerous bird on earth In 1858 Passenger Pigeon hunting became a big business By 1900 they became extinct from overharvest and habitat loss. The complexity and rich diversity of life found in forests provides many vital services to human beings Nonetheless humans are destroying forest biodiversity at an alarming rate The conversion of forests to agricultural land overgrazing unsustainabl To overcome this constraint Andean people have always had to be strategic to ensure that they have enough food and enough of the right kinds of food Instead of fighting the restrictions that their location and climate impose on food production they Agricultural biodiversity includes ecosystems animals plants and microorganisms related to food and agriculture Today most species of crops and domesticated livestock are the result of thousands of years of human intervention such as selective breed Sustaining Aquatic Biodiversity.
