Wildlife across the planet is disappearing at an alarming pace, according to the latest Living Planet Report 2024, released by the World Wildlife Fund (WWF) in collaboration with the Zoological Society of London (ZSL). The report reveals that monitored wildlife populations have declined by an average of 73% between 1970 and 2020, highlighting the growing impact of human activity on Earth’s ecosystems.
The findings paint a concerning picture of global biodiversity, with conservation experts warning that nature is approaching a critical tipping point. WWF describes the current situation as “a system in peril,” stressing that urgent action is needed to reverse decades of environmental damage.
The assessment is based on data collected from nearly 35,000 wildlife populations representing 5,495 vertebrate species, including mammals, birds, reptiles, amphibians, and fish. Scientists use this extensive dataset to monitor long-term population trends, making the Living Planet Report one of the world’s most comprehensive evaluations of wildlife health.
Importantly, the report clarifies that the 73% decline does not mean 73% of wildlife species have gone extinct. Instead, it reflects the average reduction in the size of monitored animal populations over the past five decades. While some species have remained stable or even recovered, many others have experienced severe declines, resulting in the overall downward global trend.
Among all ecosystems, freshwater habitats have suffered the greatest losses, with wildlife populations dropping by 85% since 1970. Rivers, lakes, and wetlands continue to face mounting pressure from pollution, habitat destruction, water extraction, and climate change, making them some of the world’s most threatened ecosystems.
Wildlife living on land has also experienced significant declines, with terrestrial populations falling by 69%, while marine species recorded a 56% decrease over the same period.
The report highlights notable regional differences as well. Latin America and the Caribbean witnessed the sharpest decline, with monitored wildlife populations falling by an average of 95%. Africa followed with a 76% decline, while the Asia-Pacific region recorded a 60% reduction. Even regions with comparatively lower losses were not spared, as North America experienced a 39% decline, and Europe and Central Asia recorded a 35% decrease.
Researchers say the primary drivers behind these losses are closely linked to human activities. Habitat destruction and degradation remain the biggest threats, fueled by expanding agriculture, urbanization, infrastructure development, and deforestation. Other major pressures include pollution, climate change, invasive species, emerging diseases, and the unsustainable exploitation of natural resources.
According to WWF, these combined threats are pushing ecosystems closer to irreversible ecological tipping points that could permanently alter biodiversity and reduce nature’s ability to support life.
The report serves as a stark reminder that protecting wildlife is no longer just about conserving individual species—it is about safeguarding the ecosystems that sustain both animals and humans. Conservationists say stronger environmental policies, habitat restoration, sustainable land use, and global cooperation will be essential to slow biodiversity loss and secure a healthier future for the planet.
