Complex societies

Since 2000, scientists, and in particular botanists, have been delving into the sentience of plants. They’ve made some amazing discoveries. Plants are not the insensate lifeforms Homo sapiens has believed for so long.

Most people, in the past and still today, think of plants as living, but sedentary things that just grew and either thrived or didn’t, but which provided humans food, medicine, and clothing. People presumed they lacked the ‘anima’ or movement and cunning of the upper echelon of life forms, animals, of which we humans, with our self-awareness and intelligence, dominate all other creatures and even the planet Earth. At least, again, that is what many think. We are now learning that we can change the Earth, but it isn’t always a smart thing to do, and that plants and ‘lower’ lifeforms might not be so much lower, and even in someways, smarter.

In reading a 2015 publication, Brilliant Green, The Surprising History and Science of Plant Intelligence, Ismarty-plants’ve learned philosophers since before Aristotle have wondered and postulated about plants, and whether they have souls, a sign of intelligence. Even Darwin and his son had views on plant intelligence which seemed to have been largely ignored. The authors of this book go on to describe plants’ ability to communicate, to remember, and to feel, see, hear, taste, and touch.

Programs like Nature on PBS are also creating shows like “What Plants Talk About,” (also known as “Smarty Plants” in Canada) which cover the discoveries about the ignored nature of plants. On Ted Talks, Stefano Mancuso  speaks on “The roots of plant intelligence,” and The New Yorker’s video “Do Bean Plants Show Intelligence,” based on the research of Michael Pollen, show scientists’ perceptions of plants are changing. Many videos are available on line to show the extraordinary discoveries about plant behaviors.

I’m sure most readers know that plants can survive without humans, but most ‘higher’ life forms cannot survive without plants and their ability to use sunlight, carbon dioxide from the air, and minerals found in the soil to produce sugars and other food substances. Depending on the species, they can live one season or for thousands of years. They clean air, water, and the soil that humans pollute. As mentioned, they take carbon dioxide from the air and release oxygen back into the air. What we often don’t know is they live in complex societies both above and below the soil, and when we decimate a forest for wood products, we can also decimate the society of entities that made the forest a healthy and productive ecosystem in the first place.

It is time for humans to stop taking plants, and other life-forms for granted and to use the products and life forms on Earth in a responsible way. Our existence depends on it.
