Earth Day is April 22 of every year. Back on April 22, 1970, 20 million Americans—10% of the U.S. population at the time—protested to bring attention to the very concerning environmental issues of the day, including oil spills, dangerous smog levels, and rivers that were so polluted that they literally caught fire. Today, Earth Day is one of the biggest civic and community event in the world and is celebrated through action to protect and restore the planet, from joining a park cleanup to joining a climate or carbon initiative to taking part in the world’s largest citizen science initiative.

Question of the Day
In a math book talking about the Fibonacci sequence, it said that often the sequence works with certain things in nature. There was a picture of a pinecone in the book. Do pinecones have anything to do with the Fibonacci sequence?
Fibonacci numbers are a series of numbers where each, after the second term, is the sum of the preceding two numbers (e.g., 1, 1, 2, 3, 5, 8, 13, etc.). In the study of botany, these numbers have proved useful in describing the positioning of leaves around plant stems, the spiral patterns in sunflower heads, and the scales of pinecones, to name but a few.
Advice of the Day
