In a race against the end of farmable soil, three individuals fight for change in the industry of agricultural food production, calling for a revolution.
Agricultural economists are homing in on hybrid, low-input methods that will both safeguard the environment and feed the future billions.
On this episode of One Small Step Spotlight, Lucy visits Gotham Greens, a hydroponic farming business growing leafy greens year round.
From urban farming to drones, innovation can help fill the gap between production and consumption
A core message from the researchers is that efforts to keep climate change at an acceptable level won’t be successful without a huge reduction in meat consumption.
Simply put, regenerative farming—a groundbreaking way to think about agriculture—offers a data-backed solution for mitigating and ending the world’s climate and nutritional crisis.
Consumption of meat and dairy, as well as overall calories, often exceeds nutritional recommendations. Paring down and favoring plant-based foods reduces demand, thereby reducing land clearing, fertilizer use, burping cattle, and greenhouse gas emissions.
In this film, organic market gardeners Frank and Josje talk about why the supermarket system doesn't work and how Community Supported Agriculture fits into a new story for food growing.
Composting can range from backyard bins to industrial-scale operations. Regardless, it converts organic waste into soil carbon, averting landfill methane emissions in the process.

Policymakers, entrepreneurs and farmers are increasingly looking to soils in their fight to slow climate change
Natural climate solutions are non-technological ways we can reduce emissions and remove carbon pollution from the atmosphere and store it in natural ecosystems like forests, grasslands, and coastal wetlands.
Farming seaweed, then sinking the mature plants to the bottom of the ocean, could be an effective way to fight warming. So why don’t we do it?
All your questions answered about the trillion trees everyone is talking about.
The world has spent weeks watching fires ravage the Amazon Rainforest, and along with it, our chances of meeting the Paris Agreement’s goals. What’s more, scientists predict that this critical ecosystem is nearing an irreversible tipping point: a decline from lush rainforest to dry savanna.
Protecting the forests while we are at it.
Trees are the most efficient carbon-capture machines on the planet. Through photosynthesis, they absorb carbon dioxide, the greenhouse gas that traps heat in the environment, and turn it into energy. That energy creates new leaves, longer stems and more mass — locking away carbon.
Bamboo rapidly sequesters carbon in biomass and soil and can thrive on degraded lands. Long-lived bamboo products can also store carbon over time.
In their biomass and soil, forests are powerful carbon storehouses. Protection prevents emissions from deforestation, shields that carbon, and enables ongoing carbon sequestration.
- Electricity Generation Show All
Solar and wind generators have suddenly become just as cheap as other ways to produce electric power.
LEDs (light emitting diodes) are the most energy-efficient bulbs available. Unlike older technologies, they transfer most of their energy use into light, rather than waste heat.
Waste-to-energy processes (incineration, gasification, pyrolysis) combust waste and convert it to heat and/or electricity. Emissions reductions come with health and environmental risks, however.
Biomass feedstock can replace fossil fuels for generating heat and electricity. Only perennial biomass is advisable, offering a “bridge” solution to clean, renewable production.
Standalone batteries and electric vehicles store energy. They can enable 24/7 electricity supply even when the sun isn’t shining or the wind isn’t blowing.
Smarter, more flexible electric grids can cut energy losses during distribution. They are critical to enable renewables, which are more variable than conventional electricity generation.
How can the energy industry adapt to meet the needs of a growing population while also supporting low-carbon growth? Katherine Hamilton, Director of the Project for Clean Energy and Innovation, and co-chair of the Global Future Council on the Future of Energy, says that this essential transition will not happen without collaboration between large energy companies, entrepreneurs, the finance sector and consumers.
There’s more to renewables than solar and wind. Marine energy is among them – and could play a big role in a future without dirty fossil fuels.
Small hydropower systems capture the energy of free-flowing water, without using a dam. They can replace dirty diesel generators with clean electricity generation.
