Plants love CO2. They suck it in to build their bodies and power their lives. The millions of tons of CO2 we spew into the atmosphere each year should make a plant feel like partying. Yet 70% of plants are at risk of extinction (1).
The image above represents the diversity of wildflowers I saw while hiking on the Appalachian Trail this summer. I’ve researched their historical medical uses (and wartime uses), pigmentation, symbiotic relationships, chemical and physical defenses, anatomy, and impact on insects. I hope you’ve enjoyed learning about these plants as much as I have!
Climate Change and Habitat Alteration
Climate Change brings shifting temperatures and water patterns, introduced pathogens and competitors. Since many plants have such close relationships with insects and fungi, evolutionary change grows in complexity. Most plants can’t keep up.
One of the biggest threats to plants (and everything else) is Habitat Alteration. We change the flow of rivers, turn forests into concrete deserts, build islands and literally move mountains. Geologic shifts like these used to take place over millennia. They now happen in months.
Loss of Plants, Loss of Knowledge
We change habitats to create more space for ourselves – building homes and grocery stores, retrieving fuels for our electronics and cars, and creating a lake-side view where there was none. But as we focus more and more on ourselves, we lose our awareness of everything else.
How many of us can identify the plants in our own backyards? How much medical and agricultural knowledge have we lost because “plants are boring”? When we lived within the landscape (rather than changing the landscape to suit our needs), we were forced to understand the lifeforms around us. We learned which plants to cultivate and which to avoid. We appreciated the benefits and perils of every plant.
Appreciate a Plant Today
Plants supply almost all our food and 1/2 our oxygen (thank you, algae, for the other half). Plants secure our soils and could help us battle Climate Change. Plants make beautiful flowers and support every ecosystem.
Let’s vow to get to know them better. Pick a plant in your yard and ID it. Visit an arboretum or botanical garden. Take a local botany class. And don’t forget to take some time to smell the roses.
