The two multinationals that teamed up during the Vietnam War to poison millions of people with their Agent Orange herbicide—St. Louis, Mo.-based Monsanto and Germany’s Bayer AG—are looking to become one.

Bayer has announced a bid to buy Monsanto in a deal that would expand Bayer’s GMO and pesticide holdings and add drugs to Monsanto’s global portfolio. Monsanto has rejected the latest bid, but the two are still in talks.

If Monsanto, perhaps the most hated GMO company in the world, joins hands with Bayer, one of the most hated Big Pharma corporations on Earth (whose evil deeds date back to World War I and the Nazi era), the newly formed seed-pesticide-drug behemoth would have combined annual sales of $67 billion.

That’s a staggering figure. But here’s another, even more alarming: Combined, the new mega-chemical/seed company would control 29 percent of the world’s seed market and 24 percent of the pesticide market.
