Yes — a University of Helsinki study (Sihvonen et al., eNeuro 2024) found four months of choir-based singing therapy increased grey-matter volume and improved communication in stroke survivors with aphasia.

Speech and singing run on partly different brain networks, which is why many people with aphasia can sing words they cannot say. Melodic intonation therapy builds on exactly this, and clinics are increasingly adopting singing-based rehab — cheap, safe, and joyful.

Well-designed wildlife crossings paired with directional fencing cut wildlife-vehicle collisions by 95–100% for large mammals at monitored sites — and the movement is global, with the world's largest crossing (Wallis Annenberg, over LA's ten-lane 101) opening this December.

Banff National Park proved the model with ~40 crossings since the 1980s. The US federal pilot program has $350M funded with proposals up to $1B, 85% of Colorado residents want more of them, and in April 2026 Sumatra recorded the first orangutan ever documented using a crossing.

Yes — a 2026 PNAS study published the first decade-long direct measurements of natural hydrogen flowing from billion-year-old Canadian Shield rocks beneath a mine near Timmins, Ontario: more than 140 tonnes per year from a single site.

'White' (geologic) hydrogen forms when ancient rocks react with water underground — the Earth manufacturing clean-burning fuel on its own. If deposits like this prove common, they could become a cheap clean power source using existing mine infrastructure. Caveat: it's early — extraction economics at scale are still unproven.

Rooftop and distributed solar went from about 10% of Pakistan's electricity in 2023 to roughly 28% in 2025, after ordinary citizens installed about 27 GW on homes, shops and farms in two years, per Ember and Renewables First.

Pakistan became the world's largest solar panel importer in 2024 (~17 GW in a single year), and over $12 billion in fuel imports have been avoided so far. The grid itself still has real problems and tariffs are rough for people left on it — the win here is the bottom-up speed, roughly the capacity of every fossil-fuel plant ever built in the country, added from rooftops in two years.

More than 85% of the world's roughly 120 million annual blood donations now come from voluntary, unpaid donors — and global collections grew nearly 19% between 2013 and 2023, per WHO's June 2026 global status report.

It isn't equal everywhere yet: high-income countries sit at 98.4% voluntary donations, low-income countries at 63.4%, and 24 countries still collect fewer than 5 donations per 1,000 people. But most of the world's blood supply now runs on plain generosity — the next fight is equal access to it.

Yes — mountain gorillas have climbed to 1,063 individuals (604 in the Virunga volcanoes, 459 in Bwindi), making them the only great ape on earth whose population is growing, per the IUCN Red List.

They recovered well enough that the IUCN moved them off the Critically Endangered list in 2018 — down to Endangered. The comeback spans Rwanda, Uganda and DR Congo, protected by ranger teams who know many gorillas individually. Every other great ape — chimpanzees, bonobos, orangutans, the other gorillas — is still declining.

Costa Rica's forest cover crashed to about 21% of the country in 1987 — today it's back to nearly 60%, more than doubled, per FONAFIFO and the World Bank.

The mechanism is a fuel tax that funds payments to landowners for keeping and restoring forest (payments for ecosystem services). More than 18,000 families have been paid to protect about 1.3 million hectares, with roughly USD 524 million invested per the UNFCCC. Costa Rica is often cited as the first tropical country on earth to reverse its own deforestation.

Yes — in 2025 renewables generated 33.8% of the world's electricity while coal slipped to 33.0%, the first time renewables have out-generated coal since 1919, per Ember's Global Electricity Review 2026.

The driver was solar, which added a record 636 TWh in a single year — the largest one-year jump of any electricity source ever recorded. Wind and solar together met 99% of the world's growth in electricity demand. Coal fell below a third of global electricity for the first time in the modern record. Quietly, the grid tipped.

Yes — the World Bank counts 1.5 billion fewer people in extreme poverty than in 1990: back then 43% of humanity lived below the line; today it's under 10%.

That works out to roughly 118,000 people per day rising out of extreme poverty for 35 years. And it isn't just China: exclude China entirely and the rate still fell from 33% to 12%. Progress has slowed since 2015, and most people still below the line live in sub-Saharan Africa and conflict-affected states — so it's not solved. But it may be the largest under-reported success story of our lifetime.

Yes — China's wild giant panda population has climbed from about 1,100 in the 1980s to nearly 1,900 today, and the captive population hit a record 808 in November 2025, per China's National Forestry and Grassland Administration.

In 2016 the IUCN moved the giant panda from Endangered down to Vulnerable — one of conservation's most famous upgrades. They're not out of the woods: the remaining habitat is split into dozens of isolated pockets, which is why China is stitching them together into the Giant Panda National Park. But the direction, across four decades, is genuinely up.

Western South Atlantic humpback whales have recovered from about 450 animals to roughly 25,000 — around 93% of their pre-whaling numbers — and are projected to reach 99% by 2030, per a 2019 Royal Society Open Science study (Zerbini et al.).

Commercial whaling nearly wiped them out by the 1960s. Globally, humpbacks are now listed Least Concern (IUCN, 2018), though a few groups like the Arabian Sea subpopulation are still endangered.

Solar PV is now the cheapest source of electricity in history — its cost fell about 90% between 2010 and 2023 (from ~$0.46 to ~$0.044 per kWh), per the IEA and IRENA.

In 2010, solar cost 414% more than the cheapest new fossil-fuel power; by 2023 it was 56% cheaper. The world added a record 685 GW of renewable capacity in 2024, up 22% in a single year, with solar leading. (The 'cheapest in history' framing is for new projects with good financing and sunlight; solar is intermittent, so this is generation cost, not round-the-clock power.)

There were just 10 human cases of guinea worm disease worldwide in 2025 (Chad 4, Ethiopia 4, South Sudan 2) — down from about 3.5 million a year in 1986, a drop of more than 99.99%, per the Carter Center.

Remarkably, it's being beaten with no drug and no vaccine — only clean-water education, cloth water filters, and tracking down every single case. If the count holds, guinea worm becomes the second human disease ever eradicated, after smallpox. The 2025 figure is provisional until each country confirms it.

Yes — under the Montreal Protocol the ozone layer is on track to recover to 1980 levels by about 2040 for most of the world, 2045 over the Arctic, and 2066 over Antarctica, per the WMO/UNEP 2022 Scientific Assessment.

The 2025 Antarctic ozone hole was the fifth smallest since 1992, about 30% smaller than the 2006 record, and closed on 1 December — the earliest since 2019. Phasing out the ozone-eating chemicals also spared the planet roughly 0.5°C of extra warming.

As of the 2024 census (released May 2025), there are 2,401 Iberian lynx in Spain and Portugal — up from just 62 breeding adults in 2001, per the IUCN.

The IUCN calls it the greatest recovery of any cat species ever achieved through conservation, and in June 2024 moved the lynx from Endangered to Vulnerable. 844 cubs were born in 2024 alone. It's still listed Vulnerable and depends on a fragile wild-rabbit food supply, so the work isn't finished.
