Chennai : The best way to prevent a disaster or any crisis is to take precautionary measures, said actor Arjun pledging his support for the Save Soil Movement. Sadhguru, Founder-Isha Foundation, launched the global movement to Save Soil from extinction in March this year and is currently on a 100-day 30,000-km lone motorcycle journey to build global consensus to reverse and halt further soil degradation. A major global crisis is desertification. Fertile soil of our Mother Earth is losing its microbes and vital organisms and turning into mere sand,” said the actor elaborating on the need to save soil. He said “commercial farming practices” have slowly eroded soil health over the years leading to desertification and added that “it will soon become the biggest natural disaster (and) growing food will be the biggest problem.”
