Without plants, we wouldn't exist, but we take them largely for granted. We know that vegetables are plants, but all animals, either directly by eating plants, or indirectly by eating other animals that eat plants would not exist without plants. Many luxuries and condiments, and other useful substances such as fibers, lumber, coal and oil, medicines, and and many drugs either depend on plants or are produced by them. In the past, primative peoples used plants not only for food, shelter, clothing, and medicine, but also for hunting and fishing. Even today, ethnobotanists, are travelling to remote tropical regions and interviewing witch doctors and medicine men to preserve their knowledge on the uses of plants.
Time is short.
Bulldozers are coming. We need to identify those plants with potential for modern civilization and save them from extinction. Wildflowers are Native Plants . That is, plants that are native to a particular region. You name a flower, and it's probably a wildflower somewhere in the world, or at least it was hybridized from a plant that was a wildflower somewhere.
