How many wildlife species are currently known to science?

    The exact number of wildlife species known to science is difficult to determine as new discoveries are constantly being made. However, according to the World Conservation Union (IUCN), as of 2021, there are approximately 1.3 million known species of plants and animals. This number includes mammals, birds, reptiles, amphibians, fish, insects, and various other organisms. However, scientists believe this is only a fraction of the total number of species on Earth, with estimates ranging from 8.7 million to over 30 million species in existence. It is important to note that many species remain undiscovered, especially in areas with limited access or exploration, such as remote rainforests and deep oceans. Ongoing scientific research continues to reveal new species and provide a better understanding of biodiversity.
