Visualizing the Average Lifespans of Mammals

This was originally posted on our Voronoi app. Download the app for free on iOS or Android and discover incredible data-driven charts from a variety of trusted sources. Mammals, though comprising a small fraction of Earth’s creatures, hold vital ecological roles globally. They are crucial for maintaining ecosystem health through services like pollination, seed dispersal, and predator-prey dynamics. In this visualization, we depict the average lifespans of mammals, using data from Discover Wildlife and the United Nations.

Human Lifespans on the Rise

Defined as warm-blooded creatures with hair or fur, mammals nurse their young with milk from mammary glands. While smaller animals such as weasels typically live 1-2 years, larger counterparts like elephants can thrive for decades, and bowhead whales can live for 200 years, or even longer.

Notably, human lifespans have experienced a remarkable surge. According to the UN Population Division, the global average life expectancy has surged from 47 years in 1950 to 72 years in 2022, marking a 25-year increase. This is attributed to advancements in nutrition, medication, and essential resources. However, as human longevity flourishes, it can have an adverse effect on wildlife mammal populations. To put this into numbers, over the (Read more…)
