ECOLOGY & SYSTEMS

Everything is like a battery that slowly runs out. You eat food to get a "spark," but you can't keep that spark forever; it turns into heat and floats away. We are all temporary little fires keeping the cold at bay.

The Earth is a giant LEGO set. There are no "new" pieces. Every piece of you — your skin, your breath, your bones — was once part of a dinosaur, a cloud, or a tree. We are all made of borrowed bits.

Nature has a strict math rule: for every 10 pounds of grass, you only get 1 pound of bunny. For every 10 pounds of bunny, you only get a tiny bit of fox. Most energy is lost as heat, so the top of the pyramid is always lonely.

Nature has "brakes." If there are too many deer, they eat all the food and some die, or wolves move in to help. This keeps things from getting too crazy. It's how the world stays in balance.

No one grows up alone. Bees and flowers changed together over millions of years to fit each other perfectly. You are who you are because of the people and nature around you. We are all pieces of a puzzle.

In a big family, one person might be the cook, one the cleaner, and one the gardener. In nature, species divide the work so they don't fight. Some hunt at night, some during the day. Everyone has their own special "spot."

Some animals are like the "key" to a door. If you take the key away, the whole house falls down. A tiny sea otter keeps the giant ocean forest alive. One small thing can change everything.

Nature is like a movie that never stops. A fire might burn a forest, but then new flowers grow, then bushes, then trees. Change isn't bad; it's just the next chapter of the story.

One bee isn't very smart, but a whole beehive is a genius. A forest can "think" and "talk" through its roots. When we work together, we become something much bigger and smarter than we are alone.

Life is like a game of Jenga. You can pull out many pieces and it stays up, but then one tiny piece makes the whole thing fall. Things stay the same for a long time, then change very, very fast.
