While humans were leaving the Stone Age and entering the Bronze, some Bristlecone pine trees grew from seeds to sprouts. They’ve been growing ever since. These 5,000-year-old pines are among the oldest organisms on Earth. Superlatives are also appropriate for the towering redwoods. Trees are amazing in many ways. They provide us with timber and cool us with shade, they sequester carbon and release oxygen, and are home to countless species. But they are also marvels of evolutionary adaptation. We consider the beauty and diversity of trees, and learn why their future is intertwined with ours.
