Faye D. Flam: We must conserve ageing life forms for the planet’s sake

Old trees and animals are more valuable than we thought, research finds. It’s not just about carbon capture to mitigate climate change. Sea sponges that live for millennia hold useful secrets we mustn’t lose.

Wisdom in the Ancient: Nature's Resilience in Old Age

Ancient Trees: Nature's Carbon Guardians

Like timeworn wise sages, ancient trees stand as silent guardians, their colossal size a testament to their longevity. They play a vital role in the fight against climate change by sequestering more carbon than their younger counterparts.

"Ancient trees are like nature's vaults, holding onto vast amounts of carbon that would otherwise escape into the atmosphere," explains William Keeton, a renowned forest ecologist.

Protecting the Legacy of Ancient Forests

Protecting these majestic forests is not just about preserving their beauty; it's about safeguarding our planet's future. Efforts to shield old-growth trees have been hindered by the lack of clear definitions and policies.

But change is in the air. The US Forest Service's groundbreaking survey of old growth has ignited a dialogue on their conservation. Progress is being made, despite recent setbacks, providing hope that these towering giants will continue to grace our landscapes for generations to come.

Beyond the Canopy: Ancient Animals' Vital Role

The benefits of protecting ancient lifeextend beyond trees. Animals, too, exhibit remarkable resilience and wisdom with age.

Rockfish, capable of living for over two centuries, serve as "supermothers," laying countless eggs that sustain populations. Male orcas may not live long, but their female counterparts provide invaluable guidance to their pods. Senior elephants and wolves bridge social divides within their groups.

Scientific Insights: Redefining Senescence

Ecologist Keller Kopf challenges conventional notions of aging, arguing that it's not always synonymous with decline.

"Ancient organisms possess a wealth of knowledge and experience that are essential for their communities," says Kopf. North Atlantic right whales, once thought to have a median lifespan of 22 years, have been found to reach over 130 years in southern waters, suggesting that their northern counterparts may have died prematurely.

The Need for Ancient Protectors

Ancient sponges, some living thousands of years, hold valuable climate records within their glassy skeletons. Their biochemistry may also reveal anti-aging compounds that could benefit humans. Tragically, these venerable creatures are often sacrificed by fishermen, threatening their irreplaceable presence.

We must implement policies to safeguard ancient life, both plant and animal. Incorporating protection clauses into international agreements could preserve these precious time capsules for future generations. By valuing the wisdom of age, we honor the resilience of nature and protect the irreplaceable treasures of our planet.
