How To Be A Lichen

Contain multitudes without inner conflict. Linnaeus classified lichens as plants — a notion no one questioned until Peter Rabbit creator Beatrix Potter undertook her little-known scientific studies and made the revolutionary discovery that lichens are part algae and part fungus, with a sprinkling a bacteria — three kingdoms of life in a single organism, not warring for dominance but working together to make it one of the most resilient life-forms in nature and a keystone of many ecosystems. They are what that the German microbiologist and botanist Heinrich Anton de Bary was studying when he coined the word symbiosis, which is the technology evolution invented for unselfing.

Cultivate healthy attachment that doesn’t syphon the energy of the other. Contrary to the common misconception, lichens do not parasitize the organisms on which they grow but only use them as a substrate and often contribute to the overall health of the ecosystem.

Become a pioneer of possibility amid the ruins of before. Lichens are often the first organisms to grow on the denuded rock left in the wake of landslides and earthquakes. They are the life that goes on living over the tombstones of the dead.

When you can’t change your situation, change your attitude. When environmental conditions harshen, lichens can shut down their metabolism for months, years, even decades. They survive in radioactive environments by entering a dormant state and releasing protective chemicals that block radiation and neutralize free radicals. They survive simulations of Martian conditions and even the black severity of outer space.

Know that you don’t need a partner to fulfill your life. Many lichens reproduce asexually — by dispersing diaspores containing a handful of cells from each of their inner kingdoms or simply by breaking off pieces of themselves to grow into new organisms.

Leave the world better than you found it. Lichens enrich the soil of deserts, stabilize sand dunes, and create loam from stone across the long arc of their lives. They are part of how mountains become golden sand.

Have great patience with the arc of your life. Some of the oldest living things on Earth, lichens grow at the unhurried pace of less than a millimeter per year. The continent I now live on and the continent on which I was born are drifting apart more than 250 times as fast. The Moon is leaving us four hundred times faster.
