Global spatially explicit crop water consumption shows an overall increase of 9% for 46 agricultural crops from 2010 to 2020 - Nature Food
Using the most recent Spatial Production Allocation Model 2020 crop data, agricultural green and blue water consumption is estimated. Water use increased by up to four-fifths for major crops in the past two decades.

🌍@unep.org’s Freshwater Ecosystems Explorer reveals pollution, shrinking lakes, & climate impacts on rivers worldwide. But recovery is possible—some water bodies are bouncing back! 🧪
This data platform charts the health of nearly every freshwater body on Earth. Here’s what it reveals
The Freshwater Ecosystems Explorer offers what experts call an unprecedented look at the world’s lakes, rivers and wetlands, which are increasingly under pressure from things like climate change.

Pollution isn’t just out there, it’s inside us!
Recent research indicates that human brain tissues contain about 7 g of microplastics, roughly the weight of a plastic spoon! Individuals diagnosed with #dementia had up to 10 times more microplastics in their brains.
