Lula’s “zero deforestation” plan for the Amazon

he US has been portrayed as in the grip of a maternal mortality crisis. In contrast to most other developed nations, the rate of maternal deaths in the US has been going up since the early 2000s.

But why? With the help of Saloni Dattani, a researcher at Our World in Data, Tim Harford explores how a gradual change in the way the data was gathered lies at the heart of the problem.

The claim that medical error is the third leading cause of death in the US has been zooming around the internet for years.

This would mean that only heart disease and cancer killed more people than the very people trying to treat these diseases.

But there are good reasons to be suspicious about the claim.

Professor Mary Dixon-Woods, director of The Healthcare Improvement Studies Institute, or THIS Institute, at Cambridge University, explains what’s going on.

In the past half-century, 17 percent of the Amazon — an area larger than Texas — has been converted to croplands or cattle pasture. Less forest means less recycled rain, less vapor to cool the air, less of a canopy to shield against sunlight. Under drier, hotter conditions, even the lushest of Amazonian trees will shed leaves to save water, inhibiting photosynthesis — a feedback loop that is only exacerbated by global warming.

According to the Brazilian Earth system scientist Carlos Nobre, if deforestation reaches 20 to 25 percent of the original area, “flying rivers” — rain clouds that recycle the forest’s own moisture five or six times — will weaken enough that a rainforest simply will not be able to survive in most of the Amazon Basin. Instead it will collapse into scrubby savanna, possibly in a matter of decades.

Losing the Amazon, one of the most biodiverse ecosystems on Earth, would be catastrophic for the tens of thousands of species that make their home there. What scientists are most concerned about, though, is the potential for this regional, ecological tipping point to produce knock-on effects in the global climate.

If you’ve ever thought, “What’s the Amazon rainforest ever done for me? Nothin, that’s what,” then you’re dead wrong, friend. It covers 1 percent of the Earth’s surface but houses perhaps 30 percent of its species and it’s invaluable to all life on Earth.
