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 Image
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
What they got:

❌ Crop failures
❌ Skyrocketing food prices
❌ A full-blown economic crisis

Ideology met reality—and reality won. 3/12
The immediate consequences:

🌾 Rice production fell by 40%.
🍃 Tea exports—the country’s biggest industry—collapsed.
💰 Farmers went bankrupt. 4/12
The government had to import rice for the first time in decades, spending hundreds of millions just to avoid famine.

Organic farming wasn’t feeding the country. It was starving it. 5/12
Why did this happen?

🚨 Organic yields are lower—you need more land and labor to produce the same food.

🚨 Pests don’t care about ideology—without pesticides, crops were destroyed.

🚨 Soil health declined—without synthetic fertilizers, nutrient depletion hit hard. 6/12
Sri Lanka’s leaders believed the “natural = better” myth.

Their people paid the price. 7/12
As farming failed, the entire economy crumbled:

💰 Inflation hit 50%+—food became unaffordable.
⛽ Fuel shortages—supply chains broke down.
🔥 Riots and protests—people stormed the presidential palace. 8/12
In less than a year, Sri Lanka went from a functioning country to economic disaster—all because of a reckless farming policy. 9/12
The irony?

🚨 The government reversed the ban in 2022—but the damage was done.

🚨 Farmers went back to fertilizers and pesticides, because science works.

🚨 The world ignored the lesson, and activists still push “100% organic” fantasies. 10/12
The takeaway?

1. Science beats ideology. Farming works best with innovation, not wishful thinking.

2. Organic isn’t scalable. It can supplement, but not replace modern agriculture.

3. Bad policies hurt real people. Sri Lanka didn’t just lose crops—they lost stability. 11/12
You can’t feed 8 billion people with slogans.

You need science, efficiency, and modern tools.

Which countries should learn from Sri Lanka’s mistake before making the same one? 12/12

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 Image
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
Agriculture exists because humans learned to improve on nature’s inefficiencies. 3/12

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/ Image
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/ Image
Instead of embracing a proven climate solution, they pushed for renewables-only policies.

Which led to more pollution and more coal and gas dependence. 3/ Image

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 🧵: Image
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. Image
2. Lysenko’s “Science” Was Pure Nonsense.

❌ He denied Mendelian genetics, calling it “bourgeois pseudoscience.”

❌ He claimed plants could inherit traits through exposure (called Lamarckism).

❌ He forced Soviet scientists to abandon real genetics for his fake theories. Image

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/ Image
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.
2/
When people learn a little.
They feel like they know a lot.

🚀 Confidence skyrockets.
📉 Actual knowledge? Still low.

But as they learn more, they realize how much they don’t know—so their confidence drops.

I’ve seen my share of anti-science activists.

But few are as dangerous as Vandana Shiva.

She brands herself as a "food sovereignty" advocate.

In reality? She’s an activist spreading misinformation about GMOs, pesticides, and modern agriculture.

Here’s the real story 🧵: 1/ Image
She’s an Indian activist who claims:

❌ GMOs are killing farmers.
❌ Big corporations control our food.
❌ Pesticides are poisoning the world.

It sounds noble - until you realize she ignores science, distorts facts, and blocks real solutions to hunger and poverty. 2/
Shiva has falsely claimed that GMOs caused farmer suicides in India.

Reality check:

• Farmer suicides existed long before GMOs.

• The real causes? Debt and lack of infrastructure.

• Indian farmers chose GMOs because they increased yields and cut pesticide use. 3/

I care about the environment.

Do you know one of the biggest obstacles to real progress?

Greenpeace.

What started as an activist group fighting pollution and whaling has turned into an anti-science, anti-innovation machine.

Here’s how Greenpeace lost its way 🧵: 1/12
Greenpeace was once a force for good.

In the 70s and 80s, they:

• Fought against nuclear weapons testing.
• Helped raise awareness about industrial pollution.
• Played a role in protecting whales and rainforests.

Greenpeace was fighting for real environmental issues. 2/12
Then came the shift: ideology over science.

Instead of supporting evidence-based solutions, Greenpeace began opposing anything new:

❌ GMOs – Even Golden Rice, a crop designed to prevent child blindness.

❌ Nuclear power – The best low-carbon energy source we have. 3/12
