“For a long time, people just thought of biodiversity as saving nature for its own sake,” said Robert Watson, chairman of the group that conducted the assessment. “But this report makes clear the links between biodiversity and nature and things like food security and clean water in both rich and poor countries.” B. Plumer, The New York Times
ESL Voices Lesson Plan for this post with Answer Key
“Humans are transforming Earth’s natural landscapes so dramatically that as many as one million plant and animal species are now at risk of extinction, posing a dire threat to ecosystems that people all over the world depend on for their survival, a sweeping new United Nations assessment has concluded.
The 1,500-page report, compiled by hundreds of international experts and based on thousands of scientific studies, is the most exhaustive look yet at the decline in biodiversity across the globe and the dangers that creates for human civilization.
A summary of its findings, which was approved by representatives from the United States and 131 other countries, was released Monday in Paris. The full report is set to be published this year.
Its conclusions are stark. In most major land habitats, from the savannas of Africa to the rain forests of South America, the average abundance of native plant and animal life has fallen by 20 percent or more, mainly over the past century. With the human population passing 7 billion, activities like farming, logging, poaching, fishing and mining are altering the natural world at a rate ‘unprecedented in human history.’
At the same time, a new threat has emerged: Global warming has become a major driver of wildlife decline, the assessment found, by shifting or shrinking the local climates that many mammals, birds, insects, fish and plants evolved to survive in.
When combined with the other ways humans are damaging the environment, climate change is now pushing a growing number of species, such as the Bengal tiger, closer to extinction.
As a result, biodiversity loss is projected to accelerate through 2050, particularly in the tropics, unless countries drastically step up their conservation efforts.
The report is not the first to paint a grim portrait of Earth’s ecosystems. But it goes further by detailing how closely human well-being is intertwined with the fate of other species.
In the next two years, diplomats from around the world will gather for several meetings under the Convention on Biological Diversity, a global treaty, to discuss how they can step up their efforts at conservation. Yet even in the new report’s most optimistic scenario, through 2050 the world’s nations would only slow the decline of biodiversity — not stop it.”

Discussion Questions for Comprehension /Writing
Directions: Place students in groups and have them discuss the following questions/statements. Afterwards, have the groups share their thoughts as a class. To reinforce the ideas, students can write an essay on one of the topics mentioned.
- According to the article, what activities have increased global biodiversity loss?
- Why could it become harder in the future to breed hardier crops and livestock?
- The article states that, “in addition to advocating the expansion of protected areas, the authors outline a vast array of changes aimed at limiting the drivers of biodiversity loss.” What will the following groups of people have to learn to do? Farmers and ranchers; Consumers in wealthy countries; Governments around the world.
Directions: Have groups visit the Earth Day Network and do the following:
Make a list of ways each endangered species might be saved.
Create a list of things we can all do to help the environment.
Create collages, graphs or pictures of endangered species.
Directions: Allow students 5 minutes to write down three new ideas they’ve learned about the topic from the reading, two things they did not understand in the reading, and one thing they would like to know that the article did not mention. Review the responses as a class.
