The Earth is losing species at 1,000 times the natural background rate. This is not a distant ecological curiosity — it is a civilizational threat. SDG 15 — Life on Land — commits the world to protecting, restoring, and promoting the sustainable use of terrestrial ecosystems.
Why Biodiversity Matters for Humans
Ecosystem services — pollination, clean water filtration, carbon sequestration, soil formation — are worth an estimated $125–145 trillion per year. They underpin all food systems, all economies, all human health.
The Threats
- Deforestation (12 million hectares lost annually)
- Agricultural expansion and monocultures
- Invasive species
- Pollution and climate change
- Unsustainable wildlife trade
The Kunming-Montreal Agreement
In 2022, nearly 200 nations agreed to protect 30% of land and seas by 2030 (the '30x30' target). Implementation is the challenge.
What You Can Do
- Eat less meat (livestock drives 80% of Amazon deforestation)
- Garden for wildlife — native plants, no pesticides
- Support indigenous land rights (indigenous peoples protect 80% of remaining biodiversity)
- Choose sustainable wood, paper, and food products
- Donate to rewilding projects
Protecting life on land is protecting ourselves. We are not apart from nature — we are a part of it.
