Số lượng động vật có xương sống, như động vật có vú, chim và cá đã giảm 58% từ năm 1970 đến năm 2012. Và chúng ta đang chứng kiến sự sụt giảm lớn nhất các loài nước ngọt: trung bình, đã có một sự suy giảm khổng lồ là 81% trong thời kỳ này .
WWF_The Living Planet Report documents the state of the planet—including biodiversity, ecosystems, and demand on natural resources—and what it means for humans and wildlife. Published by WWF every two years, the report brings together a variety of research to provide a comprehensive view of the health of the earth.
Populations of vertebrate animals—such as mammals, birds, and fish—have declined by 58% between 1970 and 2012. And we’re seeing the largest drop in freshwater species: on average, there’s been a whopping 81% decline in that time period.
The freshwater LPI shows that on average the abundance of populations monitored in the freshwater system has declined by eighty-one percent between 1970 and 2012.
The marine LPI shows a thirty-six percent overall decline between 1970 and 2012.
This loss of wildlife is startling, and people are at risk, too. Without action, the Earth will become much less hospitable for all of us. We must consider our impact on nature as we make development, economic, business, and lifestyle choices. A shared understanding of the link between humanity and nature is essential to making profound changes that will allow all life to thrive for generations to come.
Why are some animal populations on the decline?
Whether or not populations are in trouble depends on the resilience and location of a species, and what type of threats that species faces. Here’s a closer look at some of the top threats:
What can we do to change our course and help protect life on Earth?
Though the Living Planet Report paints a challenging picture, there’s still plenty of room for optimism. We’re already undergoing major transitions that will make for a healthier, safer, and more resilient planet.
WWF is working with governments, businesses, and communities to reduce carbon emissions, prevent habitat loss, and advance policies to fight climate change. We’re focused on protecting wildlife and conserving natural resources like forests, oceans, fresh water, and grasslands. And we’re exploring new ways to feed our population without hurting the environment.
Together we can advocate for change and find solutions that will safeguard our planet and future.
