Most people think medicine has saved the most lives.

But what if I told you that title belongs to something else?

Something…unexpected, and why we risk losing the next one 1/13 We’re 8 billion people today.
That was once unthinkable.

Yet despite wars, pandemics, and climate shocks, famine is rarer than ever.

The reason?
Modern agriculture.

Yes, really. 2/13

Life expectancy used to be 35.
Half of all children died before age 5.

A scratch could kill you.
Hunger was normal.

Then came modern agriculture, food science, and medicine.

They didn’t ruin the world.
They saved it.
Here's how:🧵 1/ Romanticizing the past is easy.
Until you look at the numbers.

In 1800:

43% of children died before age 5.
Average lifespan was around 30-40.

Famine struck entire countries.
Infectious disease was everywhere.

“Natural” wasn’t beautiful. It was brutal. 2/

These are my hands.

My hands move because of science.
Without biotech, I’d be in pain every day.

One molecule researched, tested developed and synthesized by a genetically modified cell gave me back my life.

And it made me ask:
What other innovations have saved lives? 🧵1/ Vaccines? Incredible.
Clean water? Essential.

But the biggest life-saving breakthrough?

Synthetic nitrogen and improved seeds launched the Green Revolution.

Over 3 billion lives saved.
We just used it - and we survived.

So why do we fear innovation now? 2/

“Synthetic = dangerous.”
“Natural = safe.”

This myth is everywhere.

But it’s not just wrong - it’s dangerous.
Let’s talk about how this false belief is hurting us.

🧵1/ People fear synthetic chemicals.

Even if they’re life-saving.
Even if the “natural alternative” is worse.
Even if they’re better tested than anything in nature.

Why? Because we’ve been sold a lie:
That nature is pure - and science corrupts it. 2/

Let me tell you something personal.

I live with rheumatoid arthritis - a painful autoimmune disease.

Without treatment, there are days when I wouldn’t be able to hold a pen, open a jar, or even be able to practice my passion for music....1/ But thanks to a chemical produced inside a genetically modified cell, my life is...

Normal.

One injection a week. No pain.

To me, that felt like the most life-saving technology in the world. 2/

Ever met someone who says,
“I care about science”…

But also believes GMOs are poison, vaccines are dangerous, and chemicals = bad?

That tension in their brain? 🧠
That’s called cognitive dissonance.

Let’s break it down 🧵1/ Cognitive dissonance?

It’s the mental discomfort you feel when you hold two conflicting beliefs at the same time.

Example:

🧪 “I trust science”
❌ “But I don’t trust vaccines”
= Brain error detected

Your brain doesn’t like contradictions.

So it tries to fix the tension. 2/

As a scientist, every time RFK Jr. speaks, I feel a mix of dread and duty.

Not because his arguments are hard to refute.

But because I know they’ll spread faster than the facts ever will. 1/ He doesn’t need evidence.

Just fear.
Just a microphone.

Just enough scientific-sounding words to confuse the public.

And every time, I think: 2/

Europe made a colossal mistake.

They banned GM crops while the rest of the world embraced them.

Now we rely on imports and miss out on a more sustainable agriculture.

Here’s the story of Europe’s GMO debacle 🧵1/ First, let’s start with the facts: Europe has some of the most advanced research in plant science and agriculture.

Yet, nearly all GMO cultivation is banned.

Why? Because of fear - not science. 2/

I’m a scientist.
Every time I hit "post," I hesitate.
Not because I doubt the science.

But because I know what’s coming....1/ Outrage, accusations, and bad-faith attacks.

People who don’t care about evidence will twist my words to fit their narrative. 2/

France just quietly banned something from school lunches.

Not junk food.
Not sugar.
Soy.

Yes, you read that right. Soy.

Let's check it out. 🧵 1/ More precisely: ANSES recommends avoiding soy-based ingredients rich in isoflavones in collective catering.

Think schools. Hospitals. Canteens.

Why?
Because isoflavones can act like hormones. 2/

🚨 Greenpeace just lost $667 million in court.

This could be the biggest financial hit the organization has ever faced.

Lies, sabotage, and reckless activism that does more harm than good.

It’s time to talk about what Greenpeace really is.
🧵👇 1️⃣ They ignore science when it doesn’t fit their agenda

Greenpeace opposes GMOs even though they can reduce pesticide use and fight malnutrition.

They fought Golden Rice, a vitamin A-enriched crop that could have saved millions from blindness and death.

A chemical’s name tells you nothing about whether it’s safe or dangerous.

But that doesn’t stop people from freaking out over “scary-sounding” chemicals while trusting “natural” ones without question.

Let’s fix that. 🧵👇 Ever heard of dihydrogen monoxide?
Sounds dangerous, right?

That’s water. 💧 You drink it every day.

π is everywhere. And no, not just in circles.

You learned π (3.14…) in school and probably thought it was just about circles.

Wrong. π is one of the most important numbers in science

It shapes your world in ways you never realized: 🧵1/
#piDay2025 Let’s start with medicine.

MRI scans? Based on π.

Drug design? Quantum mechanics, which runs on π.

Even the diffusion of oxygen in your blood follows π-based equations. 2/

I'm a Chemist.
10 years in the lab taught me one thing.
Everything you think about chemicals is wrong.
Here’s what they don’t want you to know: 🧵 1/ There’s no such thing as “chemical-free.”

That "chemical-free" label on your food, shampoo or cleaning product? It’s a lie.

Water is a chemical.
Air is made of chemicals.

If someone claims their product is “chemical-free,” they are clueless and trying to fool you. 2/

A recent publication titled "Pesticides have negative effects on non-target organisms" has received recent media attention.

Research on environmental effects is always valuable, and this study needs to be put into context.

Let me do that here: 🧵👇 1/ 1. The Study Focuses on Effects, Not Risk.

The research highlights potential negative effects of pesticides but does not assess real-world risk. This is a critical distinction in toxicology.

Risk = Hazard × Exposure. 2/

People hear “pesticide” and think:

→ Toxic.
→ Unnatural.
→ Dangerous.

But here’s the truth:
Pesticides are not evil.

They are essential for food security, sustainability, and preventing famine.

Here’s why they have a bad image - but shouldn’t 🧵: 1/ 1. The Word “Pesticide” Sounds Scary.

🚨 The media loves to use "chemicals" and "toxins" to scare people.

🚨Meanwhile, they ignore one simple fact: Even organic farmers use pesticides.

🚨In fact, some natural pesticides are more toxic than synthetic ones. 2/

One of the biggest myths in agriculture?
“We should farm like nature.”

It sounds nice - but it’s completely unscientific.

Modern farming isn’t about mimicking nature.
It’s about improving on it.

Here’s why the “mimic nature” strategy fails 🧵: 1/12 1. Nature is not optimized for feeding people

🚨 Wild plants don’t produce enough food.
🚨 Natural soils aren’t nutrient-balanced.
🚨 Pests and diseases don’t stop because we “respect ecosystems.”

If we farmed exactly like nature, we’d be starving. 2/12

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 The government banned chemical fertilizers and pesticides to become the first fully organic nation.

They promised:

✅ Healthier food.
✅ Environmental benefits.
✅ Self-sufficient agriculture. 2/12

The biggest paradoxes of modern environmentalism?

🚨 They demand solutions for climate change and food security.

🚨 But they reject the best technologies to solve those problems.

From GMOs to nuclear energy, ideology keeps blocking progress.
Here’s why it’s a problem 🧵: 1/ 1. The war on nuclear energy.

Environmentalists claim they want low-carbon energy.

Yet, they oppose nuclear.
The most reliable, scalable clean energy source.

❌ “Too dangerous.”
(Despite being safer than coal/oil/gas).

❌ “Too expensive.”
(Ignoring wind/solar subsidies). 2/

One of the most dangerous things in history?
When politics replaces science.

That’s exactly what happened in the Soviet Union under Trofim Lysenko.

A man whose pseudoscience led to famine, ruined careers, and millions of deaths.

His ideology destroyed Soviet agriculture 🧵: 1. Who was Trofim Lysenko?

🚜 A Soviet agronomist who rejected genetics and evolutionary biology.

🚨 He claimed crops could be “trained” to grow better - without needing selective breeding or genetics.

📢 Stalin loved it.

The problem? Lysenko was completely wrong.

The loudest voices often know the least.

It’s called the Dunning-Kruger Effect - and once you see it, you can’t unsee it.

Here’s why it explains everything from anti-vaxxers to flat-earthers 🧵: 1/ In 1999, psychologists David Dunning and Justin Kruger made a hilarious but disturbing discovery:

People who know the least often overestimate their competence—while true experts doubt themselves.

In short:
❌ Ignorance breeds confidence.
✅ Knowledge breeds humility.
