"Billion Dollar Crop," a 1994 Australian documentary, explores the history, diverse uses, and future of cannabis, focusing on the versatile and potentially revolutionary plant's potential.

The film highlights how recently developed, non-drug hemp varieties are being researched and cultivated globally for their versatile qualities and environmental benefits. It showcases hemp as an industrial fiber, offering alternatives to wood for paper, cotton for clothes, and plywood for construction, thereby benefiting forests and topsoil.

Produced with Michael Cordell and Jeffrey Bruer, and directed by Barbara Ann Chobocky, the DVD is available from Bull Frog Films.

African smallholder farming faces low productivity due to depleted soil nutrients, hindering livelihoods and impacting biodiversity. Safi Organics addresses this by producing village-level fertilizer from local agricultural by-products. This technology reduces costs, sequesters carbon, and can boost farmers' yields by up to 30%.

The Ellen MacArthur Foundation, a UK charity accelerating the circular economy, supports such initiatives. Learn more about their Food initiative, Circular Economy in Africa, and Safi Organics. For more on the Foundation's work, visit their website.

His agricultural expertise, including soil science and micro-intensive farming, culminated in the 2012 establishment of the Empower School & Farm in Umatilla, Florida.

This residential program trains individuals in Christian discipleship, micro-enterprise, sustainable agriculture, and world missions. This talk was presented at a TEDx event. Learn more at https://www.ted.com/tedx.

Former U.S. Energy Secretary Dr. Steven Chu, who oversaw a doubling of renewable energy

Former U.S. Energy Secretary Dr. Steven Chu, who oversaw a doubling of renewable energy deployment from 2009-2013, addresses if falling fossil fuel prices threaten wind and solar power.

Chu explains that 78% of U.S. economies have state-mandated renewable portfolio standards, requiring a fraction of clean energy. Renewables, currently supplying 13% of U.S. electricity, have seen significant cost reductions. Wind power, even without subsidies, is nearly as inexpensive as natural gas.

Solar generation in sunny regions nears cost parity with new natural gas plants. Wind and solar costs are projected to decline for decades, potentially making them competitive with any new energy source across much of the U.S. within a decade.
