By the year 2050, the Earth's population will reach more than 9 billion people. With so many mouths to feed, agribusiness giants have argued that genetically modified crops are the answer to global food security as these plants have been spliced and diced to resist herbicides and pesticides and (theoretically) yield more crops.
However, a new analysis from the Environmental Working Group (EWG) slams this conventional agribusiness argument—and recommends much more sustainable solutions to feed the world.

The report, Feeding the World Without GMOs, argues that genetically engineered crops (also known as GE or GMOs) have not significantly improved the yields of crops such as corn and soy. Emily Cassidy, an EWG research analyst who authored the report, found that in the last 20 years, yields of both GE corn and soy have been no different from traditionally bred corn and soy grown in western Europe, where GE crops are banned. Additionally, a recent case study in Africa found that crops that were crossbred for drought tolerance using traditional techniques improved yields 30 percent more than GE varieties, she wrote.
The report also said that in the two decades that GE crops have been a mainstay in conventional agriculture, they "have not substantially improved global food security" and have instead increased the use of toxic herbicides and led to herbicide-resistant "superweeds." (FYI: superweeds have spread to more than 60 million acres of U.S. farmland, wreaking environmental and economic havoc along the way).
She pointed out that while corn and soybeans take up the vast majority (about 80 percent) of global land devoted to growing GE crops, they are not even used to feed people but instead as animal feed or fuel.
Unfortunately, this practice is unlikely to change in light of increased consumption of meat around the world, as well as U.S. biofuel policy requiring production of millions of gallons of corn ethanol to blend into gasoline, Cassidy observed. “Seed companies’ investment in improving the yields of GMOs in already high-yielding areas does little to improve food security; it mainly helps line the pockets of seed and chemical companies and producers of corn ethanol,” she said. “The world’s resources would be better spent focusing on strategies to actually increase food supplies and access to basic resources for the poor, small farmers who need it most.”
Gary Hirshberg, chairman of Just Label It, an organization advocating for federal labeling of GMO foods that also provided funding for the EWG report added, "Biotech companies and their customers in chemical agriculture have been attempting to sell the benefits of GMOs for two decades. Between exaggerated claims about feeding the world and a dramatic escalation in the use of toxic pesticides, it is no wonder consumers are increasingly skeptical."
Fortunately, as Cassidy noted, there are ways out of this mess that will not only produce enough food for the world’s burgeoning population but will also make minimal impacts on our environment. It comes down to four main approaches:
- Smarter use of fertilizers: Fertilizer should be used in places with nutrient-poor soils where it would have the greatest impact, instead of over-fertilizing industrial-scale farms. This switch could increase global production of major cereals by 30 percent, the report said.
- A dramatic shift in biofuels policy: A World Resources Institute analysis found that by 2050, biofuels mandates could consume the equivalent of 29 percent of all calories currently produced on the world’s croplands. According to the report, reversing course on food-based biofuels policies could alleviate the need to double the global calorie supply.
- A significant reduction in food waste: By weight, a third of all food grown around the world—accounting for a quarter of calories—goes uneaten, according to the United Nations’ Food and Agriculture Organization. Food gets tossed before it reaches the market, much less anyone's plate. So in theory, by eliminating all food waste in fields, grocery stores and at home would increase the global calorie supply by 33 percent, the report noted.
- A better diet: Meat production currently uses up three-quarters of all agricultural land, and on average, it takes about 10 calories of animal feed to produce just one calorie of meat. This suggests that a shift from grain-fed beef to a diet emphasizing chicken or grass-fed beef could reduce the amount of land devoted to growing animal feed such as corn and soy (Beef also stands far above the production of other livestock for its negative environmental impact).
Cassidy concluded that investment in genetic engineering is no substitute for solving the real causes of food insecurity and poverty, such as improving access to basic resources and infrastructure in developing countries.
"The alternative strategies of smarter resource use, improving the livelihoods of small farmers, reducing food waste and changing diets could double calorie availability and reduce the environmental burden of food production, all without relying on GE foods," she wrote.

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

Kokia drynarioides is a small but significant flowering tree endemic to Hawaii's dry forests. Native Hawaiians used its large, scarlet flowers to make lei. Its sap was used as dye for ropes and nets. Its bark was used medicinally to treat thrush.
States that invest heavily in renewable energy will generate billions of dollars in health benefits in the next decade instead of spending billions to take care of people getting sick from air pollution caused by burning fossil fuels, according to a new study from MIT and reported on by The Verge.
Hawaii's Kilauea volcano could be gearing up for an eruption after a pond of water was discovered inside its summit crater for the first time in recorded history, according to the AP.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.
Humanity faced its hottest month in at least 140 years in July, the US National Oceanic and Atmospheric Administration (NOAA) said on Thursday. The finding confirms similar analysis provided by its EU counterparts.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.
It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
