We continue to try to destroy it, but the human (not just for the native inhabitants) benefits of conserving natural habitats is huge. Healthy ecosystems directly support human health, food security, economic stability, climate resilience, and wellbeing.
The world’s ecosystems provide services valued at an estimated US$125–140 trillion per year, including clean water, pollination, soil formation, flood mitigation, and climate regulation. When habitats are destroyed, these services become expensive or impossible to replace.
Approximately 75% of global food crops rely at least partly on animal pollination. Habitat loss is considered one of the greatest threats to pollinators worldwide.
Native ecosystems protect water supplies
* Forests and wetlands naturally filter pollutants and sediments from water.
* More than one-third of the world’s largest cities obtain a significant portion of their drinking water from protected forested catchments.
* Restoring wetlands can reduce water treatment costs by millions of dollars annually.
Forests absorb roughly 7.6 billion tonnes of CO₂ annually, helping slow climate change.
Coastal habitats such as mangroves can reduce wave heights by up to 66%, protecting communities from storms and flooding.
Studies have found that people who spend at least 120 minutes per week in nature report significantly better physical and mental health.
Benefits include:
* Lower stress levels
* Reduced anxiety and depression
* Improved cardiovascular health
* Better sleep quality
Australia has already lost or degraded more than 50% of many native ecosystems since European settlement. Habitat loss remains the leading threat to most threatened Australian species.
Healthy native habitats provide Australians with:
* Cleaner water
* Pollination for crops
* Protection from floods and erosion
* Carbon storage
* Recreational and tourism opportunities
* Improved physical and mental health
We do not conserve native habitats only for wildlife. We conserve them because human survival, health, food security, clean water, economic prosperity, and climate resilience all depend on functioning natural ecosystems.
