The biggest public health problem today isn’t chemicals. It’s scientific illiteracy.

I’m not a bot. I’m a chemist. I’m a human with a PhD trying to talk about science. My goal is simple, make people smarter, not angrier. Science, explained clearly. If you’re human too, drop a “Hi” so I know I’m not shouting into the botnet.

The appeal to nature fallacy isn’t cute or harmless. It’s the reason people fear medicine, vaccines, GMOs, and chemistry itself. It’s not “back to nature.” It’s back to ignorance.

What happens when farmers plant GMOs? A new study from Bangladesh shows the answer: ⬆️More yield. ⬇️Less pesticide. ⬆️Higher income. Let’s unpack the data 🧵1/

Energy demand keeps rising. Food demand keeps rising. But our policies are stuck in 1970. It’s time to remove the ideological blinders. Because the world needs more power and more food — Not more fear. Let’s talk about nuclear and GMOs. 🧵1/

I’ve played nice. I’ve held my tongue. But no more. The lie that vaccines are dangerous is killing people. We have lives to protect. Vaccines are safe, effective, and essential. Enough of the fear-mongering.

I’m in the other place. What’s this place like. Is it worth me paying here?

France just spent €11 million to answer one question: Are people living near vineyards dangerously exposed to pesticides? The results are in. 🧵 1/

all joking aside… it’s insane how people trust idiots over scientists. i can’t be the only one who feels this?

🇲🇽🙅‍♀️🧬🌽 Mexico just banned genetically modified corn. Turns out the US isn't the only place with RFK Jr brain worms. GM crops reduce pesticide use, increase yields, reduce runoff, and more. This is a rejection of science and progress. mimorelia.com/noticias/mex...

Bad policies destroy nations. In 2021, Sri Lanka banned synthetic fertilizers and pesticides overnight - forcing the country into 100% organic farming. The result? Economic collapse, food shortages, and mass protests. Here’s what happened 🧵: 1/12

Europe made a colossal mistake: They banned genetically modified organisms (GMOs) while the rest of the world embraced them. Now we rely on imports, pay more for food, and miss out on sustainable agriculture. Here’s the story of Europe’s GMO debacle 🧵:

When people say to stop using pesticides, I always respond with: Which of the following are you okay with? Losing 30-40% of crops to pests? Clearing more land for farming? Children weeding manually? Higher food prices? Lower food quality? Invasive pests? Seriously, which one?

→ Too much CO₂? Nuclear power. → Too many diseases? Vaccines. → Too cold? Air conditioning. → Crop failures? Modern Ag. ↳ Our future is rooted in science and progress.

Every person who claims “modern agriculture” is evil, should be required to rely solely on what they can grow in their own garden. Most wouldn’t last a single day without visiting a supermarket stocked with affordable, safe, and abundant food.

Almost everything you eat has been modified genetically by humans.

In farming, there’s a growing trend toward "mimicking nature" a strategy embraced by organic farming, regenerative agriculture, and agroecology. The assumption? Nature knows best. But is this true? Let’s dig into why this idea often falls short. 1/

If you want more nature, you need highly productive agriculture. Those who enjoy our centuries-old cultural landscapes also need more extensive agriculture. It's not all that difficult actually...

Should really be common knowledge taught in schools: natural ≠ safe ≠ efficient

Remember hand-weeding entire fields just to grow a few vegetables? No, me neither. Because modern agriculture works.

Natural doesn’t always mean safe. Cyanide in almonds, deadly mushrooms, venomous snakes, influenza, polio and measles are all natural. Does that make them good for you? ↳ No. The word “natural” is marketing. → Not a safety or efficacy guarantee.

Chemistry saves lives. From antibiotics to clean drinking water to the plastic in your phone. Synthetic chemicals are why modern life is safe, healthy, and convenient. Fear of “man-made” chemicals ignores the incredible benefits they bring.

Whether a chemical is man-made or natural tells you precisely nothing about how dangerous it is.

Almost everything we eat has been modified by humans, and Brussels sprouts are no exception. Through centuries of selective breeding, we’ve turned wild, bitter plants into the tiny green cabbages we know today.

Genetics, simplified with gummy bears. This creative diagram uses a ‘family tree’ of gummy bears to illustrate how traits are passed down through generations. The ‘parents’ at the top are red and yellow bears, and their ‘offspring’ show mixed colors, representing genetic variation.

Fortunately, I didn’t throw out my black plastic utensils over a mathematical error made by a group of people who know nothing about toxicology. nationalpost.com/news/canada/...

Photosynthesis is a molecular miracle: light becomes energy. Plants are nature's first chemists, crafting food from air and water. Without plants, there's no food chain. Plants fuel the world.

❎Germany bet on green. ☢️France bet on nuclear. The results? One country struggles with coal and imports, while the other enjoys stable, low-carbon electricity. France is Europe’s energy success story.

Gravity isn't pulling you down; space-time is pushing you along. Einstein's insight showed how mass warps the fabric of reality. Objects don't fall; they follow the path the universe carves.

Evolution isn't progress-it's survival. Traits that thrive are traits that persist. Natural selection rewards what works, not what's ideal. Change isn't optional in nature. It's the rule.

Energy doesn't disappear; it changes form. That's the first law of thermodynamics. Transforming energy efficiently requires design. Waste happens when systems fail. Harnessing energy is a balance between conservation and conversion.

The new glyphosate study about “neuroinflammation” that’s been going viral? It’s in mice that were force fed glyphosate at dosages 100,000 - 1,000,000 times greater than what people would be exposed to - for 13 weeks straight. 1/

Q: “Where’s the evidence GM crops are safe?” A: “Here, here, and here.” Q: “But, they have never been thoroughly tested.” A: “Yes they have. Look here and here.” Q: “But, Big Ag is hiding the truth.” A: “No, the data is here and here.” Q: But, I found this YouTube video….

I want to debunk the myth that:- “Modern farming is a health disaster.” Sounds dramatic, doesn’t it? But there’s no evidence to back it up. Let me break it down. What’s Being Claimed?

We are alive today because modern agriculture has harnessed innovation to grow more food, diversify diets, and meet the nutritional needs of a growing global population.

Over the last century, we've dramatically increased agricultural productivity and food security through science and innovation. Why would we want to reverse that progress?

The appeal to nature fallacy: the false belief "natural" is better. Natural things that can kill you? Pathogenic microbes. Smallpox virus: natural. SARS-CoV-2. Poliovirus. Rabies virus. Yersinia pestis. Bacillus anthracis. Malaria Plasmodium. Naegleria fowleri, “brain-eating amoeba”? Natural. 1/
