April 30, 2021, is Arbor Day; a day when we are encouraged to "plant a tree". It would be appropriate to adopt a second slogan, "feed a tree". Feeding-a-tree can be accomplished by implementing a greenhouse operating procedure that uses our carbon emissions ("carbon dioxide", "CO2") to enrich the atmosphere.
American President Joe Biden and his Climate Crisis Czar John Kerry are leading a campaign to starve-trees (and humanity). It is based on the mistaken belief that CO2 provides us with a global, temperature-control knob. Astonishingly, the alarmists' own climate models overwhelmingly debunk the "climate-emergency" fear mongering.
