The study of plants is vital because they are a fundamental part of life on Earth, which generates the oxygen, food, fibres, fuel and medicine that allow humans to exist. Through photosynthesis, plants absorb carbon dioxide, a greenhouse gas that in large amounts can affect global climate. Additionally, they are influential in the water cycle. A good understanding of plants is crucial to the future of human societies.
~ Excerpt from Wikipedia
Things would look very grim for the future of human societies if dependant on my knowledge of plants...
Pink ~ I have no idea what these flowers are called.
Red ~ I have no idea what these ones are called either.
Green ~ Leaves! ...but the name of the plant from which they sprout from I am clueless.
Yellow ~ Oooh I know this! Rosella! Named simply here as 'yellow' in keeping with my clueless colour theme
Why do people give each other flowers? To celebrate various important occasions, they're killing living creatures? Why restrict it to plants? "Sweetheart, let's make up. Have this deceased squirrel."
~The Washington Post
Here's an idea. Why not give a friend or loved one a flower photo print? Much sweeter than a dead smelly squirrel.
