Model Answer

The Living Planet Report 2026 reports a 73% average decline in monitored vertebrate populations between 1970 and 2022. It measures changes in population abundance, not a 73% loss of all animals or species.

What Wildlife Decline Indicates

1. Population trends reflect changes in monitored mammals, birds, reptiles, amphibians and fish.
2. Ecological stress indicates deteriorating habitats and ecosystem health.
3. Uneven decline reveals differences across ecosystems. e.g: Freshwater populations declined by 85%.
4. Measurement limitations arise because unmonitored species and individual animal losses are not directly counted.

Major Causes of Biodiversity Loss

1. Habitat destruction reduces wildlife populations. e.g: Deforestation and agricultural expansion.
2. Overexploitation threatens species through hunting, fishing and illegal trade.
3. Climate change alters habitats and breeding patterns. e.g: Coral bleaching.
4. Pollution damages terrestrial and aquatic ecosystems. e.g: Pesticides and plastic waste.
5. Invasive species compete with native biodiversity. e.g: Lantana in Indian forests.

Way Forward

1. Habitat restoration through protected areas and ecological corridors. e.g: Project Tiger.
2. Scientific monitoring using population surveys, camera traps and genetic tools.
3. Community participation through conservation-linked livelihoods. e.g: Joint Forest Management.
4. Global cooperation under the Kunming-Montreal Global Biodiversity Framework.

Wildlife decline signals weakening ecosystems, not simply disappearing animals. Conservation must combine accurate monitoring, habitat protection and sustainable resource use.
