Agroecology, a back-to-nature farming approach based on ecological science, is growing into a movement proponents hope will transform the way we grow food. “Farming the land as if nature doesn’t matter has been the model for much of the Western world’s food production system,” wrote agroecology advocates Daniel Moss and Mark Bittman in The New York Times recently. “The results haven’t been pretty: depleted soil, chemically fouled waters, … a worsening of public health and more.”

Autonomous farming robots that target weeds directly are poised to disrupt the current practice of mass spraying of herbicides.

Swiss company ecoRobotix is one of several newcomers in the emerging field of digital agriculture. Its solar-powered robot, which looks something like a pingpong table on wheels, can identify and spray weeds for 12 hours straight without an operator. Its developers believe it will use 20 times less herbicide than traditional methods that involve spraying entire fields.

Hawaii’s Kilauea volcano erupted from its summit early Thursday, shooting a plume of ash about 30,000 feet into the sky. The explosion happened at about 6 a.m. HST after two weeks of volcanic activity. More than a dozen fissures east of the crater already spewed lava into neighborhoods, destroying at least 26 homes and 10 other structures. Hawaii Volcanoes National Park closed May 11 in anticipation of a possible eruption, and officials said they didn’t expect the explosion to be deadly as long as people stayed out of the park.

Two months ago our electric co-op magazine reported on the efforts of volunteer linemen from Missouri to bring electric power to a remote village in the Bolivian Andes. It was no small effort. At 13,000 feet, with no auxiliary power, the volunteers set poles and strung lines while willing villagers dug placement holes by hand and helped lift heavy cables. All received their reward when a single bulb washed the village leader’s home with light. For the people of Chapasirca, life is brighter now.

An environmental group filed the first of several expected lawsuits late Monday over President Donald Trump’s scaling down of two national monuments in Utah. The administration is reducing Bears Ears National Monument from 1.3 million acres to less than 202,000 acres and Grand Staircase–Escalante monument from nearly 1.9 million acres to about 1 million acres. Conservationists and Native American tribes say the decision puts at risk thousands of archaeological sites that have historical, scientific, and religious significance.

Geostorm is Hollywood’s latest disaster drama. The movie depicts a fictional, futuristic world where scientists use a satellite system to control the Earth’s weather and battle climate change—until the system suddenly goes awry and attacks the planet. Critics called the movie’s technology laughable, but some researchers believe geoengineering isn’t a thing to take lightly.

WASHINGTON—Environmental Protection Agency (EPA) Administrator Scott Pruitt announced Monday he plans to eliminate the Clean Power Plan, an Obama-era edict to regulate greenhouse gas emissions. The Clean Power Plan required states to meet certain benchmarks for carbon emission reductions. The plan also included an incentive for states that proactively worked on renewable energy initiatives. President Barack Obama unveiled the rule in 2015 and predicted it would prevent thousands of premature deaths and reduce asthma attacks in children.
