Although coral reefs all over the world have been damaged by rising sea temperatures, leading to wide-scale bleaching - it turns out these ghostly white tropical reefs seem to still remain rich sources of micronutrients.
This doesn't mean we should stop trying to prevent coral bleaching events, but it does mean that where the damage has been done, there is still some hope. This is particularly good news for the many coastal communities that rely on reefs for food.
There's a lot we can learn from Tallinn it turns out.
The Estonian capital is set to be the European Green Capital for 2023, due to its innovative and modern approach to sustainability.
What's particularly impressive about Tallinn is that it used to be home to a number of heavily polluting industries. It's a shining example of how change is always possible, and hopefully a blueprint for other cities in Europe and beyond.
There's something really compelling about any story to do with a species returning from the brink of extinction. While it's of course terrible that things reached a tipping point like this, it also goes to show that there is always hope - even when the worst possible outcome seems inevitable.
This particular case is fascinating. The tiny tequila splitfin disappeared from the wild in 2003 due to human activity, but thanks to the efforts of conservation centres, colonies of this little freshwater species are thriving once again.
While the climate crisis gets the most attention, the biodiversity crisis is something we should all be paying a lot more attention to. That's why this company's project, combining AI with drones, is so fantastic. It's a faster, cheaper way to tackle deforestation.
At the same time, however, it doesn't cause the issues often found with tree-planting schemes. The method is designed to boost the health of the surrounding ecosystem, while being careful to avoid monocrops and non-native species.
We were shocked to learn that (pre-pandemic) the global conference industry produced as much greenhouse gas emissions as the entirety of the United States. It's a seriously polluting sector, but a recent study has found that moving to more online-only and hybrid events could majorly benefit the planet.
According to the 2021 IPCC report, we have 8.3-9.7 years before we exceed the 1.5℃ global warming limit. But researchers say that moving conferences online could extend that deadline by around 1.5 years.
