Did you know that lichen is a great litmus test for pollution? . According to the @natural_history_museum , âlichens are able to tell us the effects of air pollution on ecosystems, not just of the number of pollution particles in the air. This is handy if you want to know how air pollution is changing ecological communities and what that means for the people who live in and rely on them. ... Lichens are miniature #ecosystems made of #fungus and an algae and/or cyanobacteria. These different life forms work (very) closely together, with the algae or cyanobacteria sitting inside the fungus. The algae or cyanobacteria provide the fungus with sugars made from sunlight, and the fungus provides the home for both of them. Lichens look like spots or clumps of colour, like someone has splashed paint onto a branch of a tree. Their colours range from green to brown to white to russet red. Even in these colours, lichens can be understated additions to tree trunks and rocks, and you might miss them at first glance. ... To grow, lichens get their nutrients from the air. Because lichens have no roots or protective surface, they cannot filter what they absorb, so whatever is in the air is taken straight inside. If there are pollutants, it can accumulate in the lichen and can become toxic very quickly.â So next time your area looks mossy and lichen-y like this one, inhale deeply đ± . . . #breathe #nature #ruins #lichen #didyouknow #pollution #ecofriendly #ecoliving (at Segromigno in Monte) https://www.instagram.com/p/CJFB7a8Hh4a/?igshid=25zp6nfbicq7
