Hey there! I’m here to tell you about a fascinating topic: farming and how it has evolved over thousands of years. Let’s dive into the story of agriculture and explore some exciting ideas for the future!
Around 10,000 years ago, humans came up with a groundbreaking way to feed themselves: agriculture! This involved plowing the land, planting seeds, watering the crops, adding fertilizers, and harvesting the produce. This cycle repeats every year, and surprisingly, we still use a similar process today.
With the industrial revolution, we started producing much more food than before. However, this increase in production also meant using a lot more resources. For example, we’re using up water from underground sources faster than they can refill. We’re also running out of phosphorus, a nutrient plants need for photosynthesis, and our soil is eroding much quicker than it can regenerate.
To tackle these challenges, we have developed techniques like precision farming and technologies such as gene editing. But even with these advancements, our ancient farming methods might not be enough to feed billions of people for the next 10,000 years. So, what can we do?
One idea is to create a food production system where resources are recycled instead of depleted. Nature already does this! In natural ecosystems, sunlight is the main energy source, and diverse plants and animals recycle nutrients and water sustainably.
We’re starting to take inspiration from these natural systems. For instance, by planting crops alongside trees, we create habitats for pollinators and pest controllers. We’re also developing new types of crops, like perennial wheat and rice, which can be harvested multiple times without needing to be replanted every year.
The goal is to grow these new crops alongside other long-lived plants in ecosystems that maintain soil, water, and nutrients. This approach combines the best of hunting and gathering with modern agriculture, offering a sustainable way to produce food on a large scale.
Hi, I’m Alex! I recently visited the Land Institute, a place that’s leading the way in developing this new form of agriculture. They’re working on creating perennial versions of grains, legumes, and oilseeds, which they grow in diverse mixtures called polycultures. These efforts could revolutionize how we farm and help reduce our environmental impact.

Research the history of agriculture and create a timeline that highlights key developments from the birth of agriculture 10,000 years ago to modern-day practices. Use images and short descriptions to make your timeline visually engaging. This will help you understand how farming has evolved over time.
Using materials like cardboard, paper, and markers, design a model of a sustainable farm. Include elements like crop rotation, water recycling systems, and habitats for pollinators. Present your model to the class and explain how it addresses the challenges of modern farming.
Set up a simple experiment to observe soil erosion. Use trays filled with soil and simulate rain using a watering can. Compare how different ground covers, like grass or bare soil, affect erosion. Record your observations and discuss how erosion impacts farming.
Research precision farming technologies such as drones, sensors, or GPS systems. Create a presentation or a poster that explains how these technologies help farmers use resources more efficiently and sustainably. Share your findings with the class.
Design a small polyculture garden by selecting a variety of plants that can grow together harmoniously. Consider factors like plant height, root depth, and nutrient needs. Plant your garden at home or school and observe how the plants interact over time.
Sure! Here’s a sanitized version of the transcript:

Hi, this is Kate from MinuteEarth. Ten thousand years ago, humans developed a revolutionary idea for feeding ourselves: agriculture! We plow land, plant crops, water, fertilize, harvest, and repeat each year. Today, we’re still following a similar process as we did 10,000 years ago. Thanks to the industrial revolution, we are producing much larger quantities of food than before. However, we are also using significantly more resources in food production. As a result, water levels in the world’s largest aquifers are declining faster than they can be replenished; our underground supply of phosphorus—a nutrient essential for plant photosynthesis—will be depleted in a few hundred years; and we are degrading the soil itself, as it erodes 50 times faster than it forms.
We can extend the life of these resources with techniques like precision farming and technologies such as gene editing, but it’s likely that no amount of retrofitting our 10,000-year-old farming methods will sustain billions of people for the next 10,000 years. So, what will future generations do about food production? One possibility is to transition to a food-making system where resources are recycled rather than depleted. This concept, though radical, already exists in nature, where sunlight is the primary energy input, and ecosystems with diverse plants and animals cycle nutrients and water within the system, using resources at a sustainable rate.
We have started to take inspiration from natural ecosystems by interspersing crops with trees to create a healthy habitat for pollinators and pest controllers, and by developing new crop varieties. For example, we are working on perennial forms of wheat, rice, and other grains that can survive multiple harvests, unlike traditional grains that require replanting each year. The goal is to eventually cultivate these new grains alongside a variety of other long-lived plants in self-sustaining ecosystems that retain soil, water, and nutrients. If we can achieve this for all our food, it would represent a fundamentally different approach to large-scale food production: a blend of hunting and gathering with modern agriculture.
Hey there, I’m Alex! I’m visiting the Land Institute, the sponsor of this video. They are pioneering a new form of agriculture that mimics natural ecosystems to help feed the world’s population with fewer environmental impacts. At the Land Institute, plant breeders and ecologists are developing perennial versions of grains, legumes, and oilseeds. The goal is to grow them in ecologically functional and diverse mixtures, known as polycultures. To learn more about how the Land Institute’s perennial polycultures could help revolutionize agriculture or to support their work, visit LandInstitute.org.
