Why does Mew Guinea have more species of birds than Bali

Explanation:

Bali is a region in Indonesia. New Guinea is found in the Oceania and it is home to the largest Islands in the world.

 New Guinea have more bird species than Bali because of more ecological space available to these avian animals.

With more space available for a specie comes the ability to improve diversity.

Bali has a lot of human control and need for available space. The ecological space available to attain diversity is therefore very limited.

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
