Photochemistry is crucial in nature since it is the core of photosynthesis, vision, and the creation of vitamin D from sunshine. Temperature-driven reactions are not the same as photochemical reactions. Photochemical pathways get access to high-energy intermediates that cannot be formed thermally, allowing reactions that would otherwise be inaccessible via thermal processes to overcome enormous activation barriers in a short period of time. The photo degradation of plastics shows how damaging photochemistry can be.
