Trees - Definition, Examples, and Why They Matter

What Makes a Tree a Tree?

A tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves. Unlike shrubs, trees typically have a single trunk and can grow to significant heights. The tree trunk provides structural support, while the leaves perform photosynthesis, converting sunlight into energy.

The Importance of Trees

Trees are vital for the environment and human well-being. They produce oxygen, absorb carbon dioxide, and provide habitat for wildlife. Without trees, life on Earth would be unsustainable.

How Trees Support the Ecosystem

• Oxygen Production: Trees produce oxygen through photosynthesis. A single mature tree can generate enough oxygen for four people annually.

• Carbon Sequestration: Trees absorb carbon dioxide, helping to combat climate change. One tree can absorb up to 48 pounds of CO2 per year.

• Biodiversity: Trees provide habitat and food for countless species, from birds to insects to mammals.

Trees and Human Health

• Mental Health: Spending time around trees reduces stress and improves mental well-being.

• Air Quality: Trees filter pollutants from the air, improving urban air quality.
