Peatlands are powerful. Here are just a few reasons why… 1. Peatland vegetation slows the flow of rainfall which helps reduce the risk of flooding in nearby towns and villages. Peatlands only cover around 3% of the world's surface but contains more carbon than all the world's rainforests.

Underneath, the sea with a ship wreck in the foreground, in the background a modern container ship, an oil rig and an offshore wind farm. The sea has tones of blue in the background, green in the middle and increasingly sandy colour
 towards the foreground. Digital drawing with visible brush strokes. Rolling hills with some woodlands in the background, some single trees, some bushes along a field path. Wildflowers of varying colours are sprinkled throughout the frame. The sky is blue with some white clouds.

I knew about pixels and voxels but was today introduced to spaxels: A spaxel (spatial pixel) is the smallest spatial element in an integral field spectroscopy dataset, representing a specific position on the sky with an associated spectrum. Taken from Maggie Aderin-Pocock‘s book WEBB‘S UNIVERSE
