This is really one of the best charts by @ourworldindata.org 📊
Amazing how much research and work goes into creating a chart like this. And it's such a good insight into society.

The threat of extinction is not spread evenly across the tree of life. To protect animals, it’s important to know which ones are most threatened and why.
Of all vertebrates (animals with a backbone and skull), amphibians are most threatened with extinction.

Vaccines are one of the most powerful tools in public health. They have saved hundreds of millions of lives by preventing deadly diseases like measles, polio, and smallpox. Before vaccines, these infections were common; surviving them often meant facing severe complications or lifelong disability.

💡New feature rolling out: switch between different indicators on our data pages!
For example, on our page showing childhood vaccination coverage, you can easily switch between the share and number of children vaccinated (and unvaccinated), and compare across vaccines or focus on a particular one.

Few things are more heartbreaking than the death of a young child.
For most of humanity’s past, these tragedies occurred all too frequently — half of all children died. This was true no matter where in the world a child was born, even in the richest countries.

This long-run data is a proxy for how the climate has changed.
Since the early 20th century, the combined effects of urbanization and higher temperatures due to climate change have gradually moved the peak blossom earlier in the year.

Rising global temperatures can influence the timing of events, such as when crops are ready to plant and harvest and when flowers and trees bloom.
One example is the timing of the peak cherry tree blossom in Kyoto, Japan, where records stretch back to the ninth century — that’s over 1200 years.
