What is the current focus on conservation biologists worldwide?
There are multiple focuses but many relate to habitat destruction and loss.
Conservation biologists focus on a multitude of topics depending on the ecosystem they study and their individual interests and resources. Many are focusing on issues related to habitat loss and destruction, as this is the leading cause of species decline worldwide.
The reasons behind this habitat loss can vary immensely: climate change, conversion of land from natural area to agriculture, increasing urbanization, exploitation of the land for natural resources such as oil and timber, loss of suitable aquatic habitat due to pollution from industry, decreased streamflow due to shrinking glacial sources of input, etc.
No matter the reason, habitat loss remains the primary factor behind the decline and extinction of most species at present.
