Challenges and Innovations in Agriculture

The video discusses the evolution of agriculture from its inception 10,000 years ago to modern practices, highlighting the challenges of resource depletion and environmental impact. It explores sustainable alternatives inspired by natural ecosystems, such as perennial crops and polycultures, and introduces the Land Institute's efforts to revolutionize agriculture with these methods.

What revolutionary idea did humans come up with 10,000 years ago to feed themselves?

• Hunting and gathering

• Fishing

• Agriculture
