Cut Beef Consumption in Half to Help Save the Earth, Says New Study
The world's population will hit 10 billion in just 30 years and all of those people need to eat. To feed that many humans with the resources Earth has, we will have to cut down the amount of beef we eat, according to a new report by the World Resources Institute.
The report makes several concrete recommendations, including cutting beef consumption. To feed a growing world, Americans will need to eat about 40 percent less beef and Europeans need to cut their consumption by 22 percent. That averages out to a burger and a half per week, as CNN reported.
This calculation is part of a 565-page report that looks at ways humans can optimize production of natural resources to sustain a growing population and navigate agriculture through the climate crisis. Titled Creating a Sustainable Food Future, the report released Wednesday identified the gaps in food production and global demand that need to be filled in order to prevent a catastrophe, according to CNN.
Right now, Americans consume an equivalent of three hamburgers per week, but beef only provides 3 percent of the calories Americans consume while it is responsible for nearly half of the agricultural land and greenhouse gas emissions associated with U.S. diets.
"This is a huge global challenge," said Tim Searchinger, the report's lead author, as USA Today reported. He suggests that consumers should shift from cattle, sheep and goats to chicken, pork and vegetable-based alternatives.
Providing a healthy diet for a population of 10 billion will require a massive overhaul to farming, which already swallows up 90 percent of all the water humans use and coughs up one-fourth of the annual global emissions that cause global warming. Yet, despite our intensive agriculture, more than 820 million people still experience chronic hunger, according to the UN, as EcoWatch reported this week.
"There is a pathway to achieve this but the challenge is even bigger than any of us thought," said Richard Waite of the World Resources Institute and a co-author of the report, as National Geographic reported.
While the report has many recommendations for dealing with the world's impending food crisis, the authors suggest that the most impactful way to keep the climate crisis at bay and to feed the world is to simply cut back on ruminant meat, according to CNN. This is especially true as more money flows into the developing world and the demand for food outpaces population growth. The demand for meat and dairy is expected to rise nearly 70 percent, while the global demand for beef, sheep and goat, is expected rise even faster to 88 percent.
"We have to produce 30 percent more food on the same land area, stop deforestation, [and] cut carbon emissions for food production by two-thirds," said Waite, as National Geographic reported.
The report says that beef, goat, and sheep farming takes up 20 times more land than farming for beans, chickpeas, and lentils per gram of protein. It also generates 20 times as much greenhouse gas emissions, according to CNN.
Besides insisting that high-meat consumers move toward more plant-based diets, the report also calls for strategies to reduce the one-third of food that is lost or wasted, use technology to boost crop yields, and improve the management of wild fisheries and aquaculture farms, according to National Geographic.

For centuries, the delicate silver dove has been a symbol of love and fidelity.
Biodiversity and Habitat Loss<p>Their near extinction is a symbol of the <a href="https://www.dw.com/en/global-biodiversity-outlook-targets-extinction-summit-new-york-pledge/a-54932895" target="_blank">biodiversity crisis</a> in the UK, largely driven by habitat destruction. Britain is now one of the countries with the most <a href="https://www.wwf.org.uk/future-of-UK-nature#:~:text=The%20UK%20is%20one%20of,than%20half%20are%20in%20decline" target="_blank">depleted nature</a> in the world according to the World Wildlife Fund. Half its plant and animal species are in decline and more than <a href="https://www.rspb.org.uk/about-the-rspb/about-us/media-centre/press-releases/let-nature-sing-wales/#:~:text=a%20natural%20tragedy.-,Over%2040%20million%20birds%20have%20vanished%20from%20UK%20skies%20in,unaware%20of%20the%20impending%20danger" target="_blank">40 million birds</a> have vanished in just half a century.</p><p>"[Turtle doves] are the canary in the [coal] mine because there are all these other species before it and after it," said Tree. "It's an umbrella for all the other species that are heading that way."</p><p>Turtle doves migrate south through Europe to sub-Saharan Africa between July and September, ending up in dry woodland and farmland areas of countries like Mali and Senegal for winter. </p><p>Droughts in West Africa and the Sahel region are believed to have contributed to the fall in turtle dove species recorded in northern Europe, with low rainfall reducing supplies of the seeds and insects the birds rely on for energy for the long journey home.</p>
Conservation and Farming<p><a href="https://www.operationturtledove.org/" target="_blank" rel="noopener noreferrer">Operation Turtle Dove,</a> a partnership project of charities including the Essex Wildlife trust, works with landowners and farmers to actively build turtle dove habitat.</p><p>Outten works with <a href="https://www.ebws.org.uk/birdsites/blue-house-farm-ewt-north-fambridge" target="_blank">Blue House Farm</a>, a 660-acre nature reserve in the UK county of Essex, where they have replicated weedy fallow plots. </p><p>"We work on it every year to make sure it's in the condition it needs to be with plants such as clovers and black medic," Outten said. "These plants are native to the landscape and produce the seed the birds feed on." </p><p>The birds eat a wide range of seeds from various plants that would have been abundant 50 or 100 years ago, added Guy Anderson, program manager for species recovery with The Royal Society for the Protection of Birds (RSPB). </p><p>"But it's simply true that with the gradual process of <a href="https://www.dw.com/en/farming-without-pesticides-how-can-we-make-agriculture-greener/a-52216796" target="_blank" rel="noopener noreferrer">intensifying our agricultural production</a>, the availability of those seeds has dropped and dropped," said Anderson.</p><p>Part of the project includes supplementary feeding — providing sources of food in the form of seed or grain. Under the Countryside Stewardship Scheme in England, farmers can receive financial support to create a turtle dove habitat. </p><p>Though they haven't recorded an increase in doves across the sites in the four years of working on the project, Outten said they are seeing improvements in how landowners and farmers manage habitat for the birds. </p>
A Turtle Dove Haven<p>The 3,500-acre Knepp Estate in West Sussex is another project taking a different approach and one of the few places where turtle dove numbers are increasing.</p><p>Isabella Tree and her husband Charlie Burrell converted their intensively farmed land into a rewilding project almost 20 years ago. They have let the land return to nature.</p><p>Just one year after they'd finished <a href="https://www.dw.com/en/uks-most-talented-architects-are-not-human/a-35952128" target="_blank">rewilding</a> the southern part of their property, they heard turtle doves for the first time. It's now a breeding hotspot for the birds with an estimated 19 pairs. Knepp is also home to <a href="https://www.rewildingbritain.org.uk/rewilding/rewilding-projects/knepp-estate" target="_blank" rel="noopener noreferrer">2% of the UK's population</a> of nightingales. </p><p>Tree is critical of supplementary feeding schemes that, in her view, are short term. She questions the chances of turtle doves getting to feed on scattered seeds before other mammals eat them first.</p>
