Organic seed should be free of genetically engineered (GE) DNA, because organic regulations prohibit genetic engineering. Unfortunately, organic crops are threatened by inadvertent contamination from GE crops. In response to the threat, the Organic Seed Growers and Trade Association (OSGATA) published a workbook, Protecting Organic Seed Integrity: The Organic Farmer’s Handbook to GE Avoidance and Testing.

Although the workbook itself is geared primarily to seed growers, the integrity of our seed supply is important to all of us. Contamination of seed planted by organic farmers will result in GE DNA in organic food and feed. This is an economic loss for the farmer, because buyers may refuse to purchase contaminated seed. Wide-scale contamination of our seed supply can destroy the genetic purity of seed varieties used by organic farmers. The workbook claims “OSGATA’s membership believes that contamination of organic seed by GE seed constitutes irreparable harm to the organic seed industry by undermining the integrity of organic seed.”
How do crops become contaminated?
There are many ways that GE DNA can find its way into other crops. During the growing season, pollen from a GE crop can travel long distances and pollinate organic crops. To help prevent this, some seed companies require seed crops to be at least 2 miles from any corn plantings, to ensure purity of the seed. Gene flow can occur as seeds are dispersed to new areas by wind, water, and animals. Another important source of GE contamination is through seed mixing. This can occur in the equipment used during planting and harvest, or during transport and storage of the harvested crop.
Why is contamination a threat?
The spread of GE DNA can happen quickly. Within a year of the release of GE alfalfa, contamination was found in the non-GE plantings of alfalfa.
Possible sources of GE contamination can be difficult to identify. For example, test plots of unapproved GE crops can be a source of unknown and unsuspected GE DNA. Before crops are deregulated and commercialized, they are field tested at undisclosed locations. More than 8,000 field trials have been planted, throughout the U.S., often near seed producing areas. Farmers may have no idea that a new experimental crop is being tested near their farm.
If genetic contamination from test plots does occur, it may be impossible to detect. Testing for GE crops is based on detecting the novel DNA that has been inserted, or the proteins made from that DNA. Testing laboratories can use DNA sequences of the approved, deregulated crops, but they do not have access to the DNA sequences of unapproved varieties being grown in field tests. Since laboratories can only test for known DNA sequences, they may be unable to detect contamination that occurs from crops in test plots. Since the location of the test plots is secret, farmers may not even be aware of the need to test. Contamination can become widespread before it is detected.
All crops are at risk of contamination, but seed crops are particularly at risk, because the GE DNA in the seed will carry over to the food crop as well. After GE crops are commercialized, they may be grown anywhere, even near seed crops, and farmers who grow them are not required to notify their neighbors.
How can risk be mitigated?
Growers of organic seed crops are taking a pro-active stance to prevent contamination. They are educating themselves about prevention methods, implementing management practices, and testing their own seed crops. The National Organic Standards Board has discussed seed purity, and plans to continue working on it.
Consumers can support these efforts by purchasing organic food and garden seeds. This is particularly important for corn, canola (and canola oil), soybeans, beets (and beet sugar), and squash.
Farmers and consumers depend on the integrity of organic seed stocks. Without action, organic seed stocks could be permanently contaminated with GE DNA.

Tuna auctions are a tourist spectacle in Tokyo. Outside the city's most famous fish market, long queues of visitors hoping for a glimpse of the action begin to form at 5 a.m. The attraction is so popular that last October the Tsukiji fish market, in operation since 1935, moved out from the city center to the district of Toyosu to cope with the crowds.

Kristan Porter grew up in a fishing family in the fishing community of Cutler, Maine, where he says all roads lead to one career path: fishing. (Porter's father was the family's lone exception. He suffered from terrible seasickness, and so became a carpenter.) The 49-year-old, who has been working on boats since he was a kid and fishing on his own since 1991, says that the recent warming of Maine's cool coastal waters has yielded unprecedented lobster landings.
The climate crisis is getting costly. Some of the world's largest companies expect to take over one trillion in losses due to climate change. Insurers are increasingly jittery and the world's largest firm has warned that the cost of premiums may soon be unaffordable for most people. Historic flooding has wiped out farmers in the Midwest.
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.

The Ganges is a lifeline for the people of India, spiritually and economically. On its journey from the Himalayas to the Bay of Bengal, it supports fishermen, farmers and an abundance of wildlife.
The river and its tributaries touch the lives of roughly 500 million people. But having flowed for millennia, today it is reaching its capacity for human and industrial waste, while simultaneously being drained for agriculture and municipal use.
Here are some of the challenges the river faces.

As a growing number of states move to pass laws that would criminalize pipeline protests and hit demonstrators with years in prison, an audio recording obtained by The Intercept showed a representative of a powerful oil and gas lobbying group bragging about the industry's success in crafting anti-protest legislation behind closed doors.
Speaking during a conference in Washington, DC in June, Derrick Morgan, senior vice president for federal and regulatory affairs at the American Fuel & Petrochemical Manufacturers (AFPM), touted "model legislation" that states across the nation have passed in recent months.
AFPM represents a number of major fossil fuel giants, including Chevron, Koch Industries and ExxonMobil.
"We've seen a lot of success at the state level, particularly starting with Oklahoma in 2017," said Morgan, citing Dakota Access Pipeline protests as the motivation behind the aggressive lobbying effort. "We're up to nine states that have passed laws that are substantially close to the model policy that you have in your packet."

"This legislation has potential to punish public participation and mischaracterize advocacy protected by the First Amendment."https://t.co/bmiHjONEhy
The audio recording comes just months after Texas Gov. Greg Abbott signed into law legislation that would punish anti-pipeline demonstrators with up to 10 years in prison, a move environmentalists condemned as a flagrant attack on free expression.
"Big Oil is hijacking our legislative system," Dallas Goldtooth of the Indigenous Environmental Network said after the Texas Senate passed the bill in May.
As The Intercept's Lee Fang reported Monday, the model legislation Morgan cited in his remarks "has been introduced in various forms in 22 states and passed in ... Texas, Louisiana, Oklahoma, Tennessee, Missouri, Indiana, Iowa, South Dakota, and North Dakota."
"The AFPM lobbyist also boasted that the template legislation has enjoyed bipartisan support," according to Fang. "In Louisiana, Democratic Gov. John Bel Edwards signed the version of the bill there, which is being challenged by the Center for Constitutional Rights. Even in Illinois, Morgan noted, 'We almost got that across the finish line in a very Democratic-dominated legislature.' The bill did not pass as it got pushed aside over time constraints at the end of the legislative session."
Many of the state bills restricting the right to protest have been "drafted by companies and passed through groups like ALEC, the secretive group of corporate lobbyists trying to rewrite state laws to benefit corporations over people." @greenpeaceusa https://t.co/ZxpTjWdrwT— Stand Up To ALEC (@StandUpToALEC) May 6, 2019
