Not a medical oncologist but 2A chems are basically considered "yeah, we can't directly link this to cancer but even healthy adults will want to stay away from this stuff; don't even think about bringing children/elderly/people with compromised immune systems around it". Other chemicals that fall into 2A are tetra-{flouro|chloro}-ethylene[1] and dimethyl sulfate[2]. You can certainly do things 'organically' without having to use Roundup[3]. Some of my hippie friends decided to buy distressed properties in Maine and 'do it all by hand' co-op style. You won't be supplying Walmart and making money hand over fist, you won't be able to use all your land all the time, but at the same time you won't be practicing short-term maximization (a mentality that directly contributed to the first Dust Bowl). 1: https://en.wikipedia.org/wiki/List_of_IARC_Group_2A_carcinogens https://en.wikipedia.org/wiki/List_of_IARC_Group_2A_carcinog... 2: Wikipedia (https://en.wikipedia.org/wiki/Dimethyl_sulfate https://en.wikipedia.org/wiki/Dimethyl_sulfate) Dimethyl sulfate is carcinogenic[7] and mutagenic, highly poisonous, corrosive, environmentally hazardous and volatile (presenting an inhalation hazard). It is considered a potential chemical weapon.[13] 3: Note that RoundUp is a Monsanto trade-name with a chemical composition that changes nearly, if not every, year due the rapid immunity weeds tend to develop against it. While wildly lucrative, its ecological impact is not unlike the overprescription of antibiotics (antibiotics indiscriminately kill good & bad bacteria :: RoundUp will kill other plants [i.e. not just weeds] that grew in tandem with those other plants to enforce "checks and balances" with a secondary-effect of allowing the rampant proliferation of more harmful weeds) edit: RoundUp ORIGINAL(tm)[4] (emphasis added) is primarily glyphosate. That's what you get at Home Depot at 5% to keep your lawn nice, green, and dandelion-free. Industrial RoundUp is a) ~40% b) has the warning Wear appropriate protective clothing to prevent skin contact. Applicators and other handlers must wear long-sleeved shirt, long pants, shoes plus socks and protective eyewear". (Again, that's the 'original' formulation. Farmers (at least in South America, I have no knowledge outside of that region, but I'd be willing to bet practices are similar worldwide) use special formulations, often designed for a specific region.) Regardless, glyphosate is still 2A[5] and just because you use it once a season on your lawn at 5% doesn't mean it doesn't cause cancer. If you smoke a cigarette once a year after getting sloshed on New Years eve, your odds of cigarette-related lung cancer increasing are quite slim; if you've been smoking two and a half packs of Reds for 40 years, on the other hand...
