Are you a nature lover? Want to explore a vast variety of diverse landscapes, wildlife, and plant life all in one nation? Despite a decline in biodiversity due to pollution and climate change, there are many nations known for their incredible biodiversity.

Data analytics company, The Swiftest, performs research on topics related to societal and environmental issues. Their Global Biodiversity Index ranks countries in terms of how biodiverse they are. In their study, they considered various factors, including the number of birds, amphibians, fish, mammals, reptiles, and vascular plant species found in each nation. Here are their findings for the top 5 most biodiverse countries in the world in 2022.
