What is one reason the number of great breasts might decrease?

The number of great breasts might decrease due to several reasons. One potential cause is the impact of climate change and habitat destruction on the populations of great bustards, which are large birds found in various regions of Europe and Asia. These birds require vast open grasslands and steppe habitats for nesting and foraging. As these natural habitats are degraded, fragmented, or converted to other land uses, the availability of suitable breeding grounds for great bustards declines, leading to a decrease in their populations. Additionally, hunting, illegal trade, and other human-induced factors can contribute to the decline of great bustards and, consequently, the reduction in the number of great breasts.
