Should We Genetically Engineer Carbon-Hungry Trees?

A genetically engineered fake meat that smells, tastes and has the same texture as a regular beef burger? Sounds impossible, but it's not for the Impossible Burger. Made from ingredients such as wheat and potato protein and coconut, it's the tactic of extracting heme (the ingredient found in the hemoglobin of cows) from leghemoglobin (a the plant alternative) that really helps the Impossible Burger succeed. This success is also a success for the environment by using less land, a quarter of the water and emitting an eighth of the greenhouse gases than is reported for livestock rearing.

During the Industrial Revolution, farmers began harvesting monoculture crops which produced promising profits but proved harmful to the soil and weakened the immune capabilities of native plants. Lately, however, permaculture practices have been on the rise amongst farmers to better diversify their yields and reduce reliance on chemicals.

"Farm to table" is a well-known saying in the food industry, but "lab to table" is also rapidly joining the rank of commonplace terminology. To both reduce the amount of animals killed and lessen the impact on the environment to raise livestock, researchers have found a way to manufacture cell-based meat that is created in a lab, yet still has the texture of meat.

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

As rising temperatures threaten marine life, the Pacific Hybreed laboratory is working to develop resilient shellfish. Their experimental breeding process attempts to uncover new genes to help a variety of shellfish withstand changing temperatures and disease, and it just might help save the fishing industry.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

In Indonesia, transferring land management rights to local residents is slow-going, but one community is setting an example for what can happen when the residents are in charge. Mandiri farmers formed a cooperative and began replacing hillsides; now, tourism to the area has increased and attitudes towards the land and community have changed.

As a way to combat climate change, scientists are experimenting with genetically modified trees as a way to draw carbon dioxide out of the atmosphere to store in its leaves, roots, and trunk. The startup Living Carbon has genetically modified poplar and pine seeds in the ground and expect them to be ready by the end of the year. Some scientists are worried about how these trees can impact forest ecosystems, but they grow faster than normal trees, allowing them to study and assess the risks quicker.

Lamakani, a small village in India, went barren and townspeople completely depended on water tankers after a drought in the 90s. One leader initiated a watershed movement. They applied a series of approaches which included things like watershed development, bans on grass grazing and tree falling, and collaborating with local artists to communicate messages of conservation. Now, the town is lush again.

After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.
