I am constantly surprised by the fact the people don't seem to realize that plants need light in order to be and stay beautiful. People seem to think they are inanimate objects. That they are not living creatures responsible for life on this planet.
Don't turn out the lights in offices where there are plants, they need this artificial light to live. Yes they can & do use florescent & LED light to pull carbon dioxide from the air & produce oxygen. That stuff we & our animals breath.
Next time you or a co-worker thinks there saving the planet from global warming by turning off the lights in offices (especially windowless) stop yourself & help the plants that give us life.
