Urban Development Turned Indian Freshwater Rivers Into Open Sewage Drains
“Your mithi is declared a drain. Okay, it's declared a drain. It was a river, fresh water river. In Delhi, we have something called the sahibi. It was a river, a fresh water river, which came and joined Yamuna. It's called the Najafkar drain today.”

“So the average is now 3.6. After, after depreciation, a new plant is closer to five.”
Dubash: Solar power costs 2 rupees per unit, 4 with storage

Gogri: Direct air capture is too energy-intensive to scale without new tech
“Direct air capture, which is there. I think it is just too energy intensive. I think it is like the current numbers are, it's three megawatt hours. Again, not taking the numbers, just too energy intensive. Right now, I really don't see a pathway to energy inte…”

“The Americans today are the world's largest producer of oil and gas. They've beaten Saudi Arabia, ok?”
IPCC 1.5°C Climate Models Mathematically Require Unproven Carbon Dioxide Removal Tech

Livestock Provide the Primary Climate Risk Adaptation for Indian Farmers

Imposing Western Veganism Demonetizes Cattle for Vulnerable Indian Farmers
“Now, if you believe in the kind of vegetarianism, veganism, which is becoming an issue, what happens to the Indian farmer? You demonetize their cattle. You take away their ability to be able to use their animal, their livestock, for the value that they will ge…”
