Most plastics today are made from fossil fuels, which are formed from the carbon-rich remains of prehistoric marine plants and algae that thrived on “ancient sunlight,” as McCurdy puts it. Thinking about these materials as ancient sunlight raised a question for McCurdy: What would happen if we made them out of “present-tense sunlight”?
“If our materials were the product of photosynthesis happening now, not only could we reduce our dependence on ancient carbon, we could store our current carbon in our materials,” she explains. “We have guilt about consumption. We’ve told each other that the moral thing to do is to reduce our consumption. Well, how’s that going?” Instead of the endless guilt trips, McCurdy sees a better path forward through the development of materials that are actively helping combat climate change by metabolizing atmospheric carbon, such as plant matter.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
