Plants produce all the oxygen we breathe and almost all the food we eat — they're the foundation of all life on Earth!
There are over 390,000 known plant species on Earth — from tiny mosses to towering 380-foot redwood trees. Plants make their own food through photosynthesis, produce the oxygen we breathe, anchor soil against erosion, and form the base of nearly every food chain on the planet.

Plants are called "producers" because they produce their own food through photosynthesis — using sunlight, water, and carbon dioxide to create glucose and oxygen. This makes them the foundation of nearly every food chain on Earth. Without plants, there would be no oxygen to breathe, no food to eat, and no shelter for the millions of species that depend on them. Every time you breathe in, you're benefiting from plants!
