“There is a big difference between dirt and soil,” filmmaker and activist Rob Herring says. “Dirt is lifeless. Soil is life.”
The Need to GROW is a new documentary about an age-old matter—soil. And although soil science is relatively young and unbelievably complex, it’s been a life source for millions of years. With somewhere around six billion microorganisms in a mere tablespoon of soil, these are galactic ecosystems which scientists are just starting to understand.
“These systems evolved over millions of years to optimize delivery of nutrients to plants, hold water in the ground and store carbon in our soils,” explains Herring, who made the film with creative partner Ryan Wirick. “Literally our air, food and water all rely on healthy soil. However, it’s estimated we’re losing 75 billion tons of soil every year. At this rate, the UN estimates that we have 60 years left of farmable topsoil. Not enough people are talking about this.”
