You may have heard of 'carbon sequestration' in the news recently, but what is carbon sequestration? And what is not carbon sequestration? In this video, I talk about what C sequestration is and the need for more carbon sequestration projects to draw down atmospheric carbon dioxide concentrations to dampen the sharply increasing greenhouse warming. I focus mainly on the effect of tilling soil in this video and how tilling reduces soils ability to sequester and store carbon because it leads to desertification. Desertification of soils is the loss of the upper organic rich layer. We are not only worsening the current warming trend by tilling and over-using pesticides, but we are also depleting the amount of farmable land on Earth and thus, depleting food supply. No-till regenerative farming can drastically increase the carbon storing capacity of soils as well as increase the health of our foods and ourselves! I also discuss some other methods of carbon sequestration, such as the more long-term method of mineral weathering, which can form carbonate minerals that store carbon for millions of years! Thanks for watching, I hope you enjoy! ;)
