Question: My Mum heard that in some parts of the world there are only 65 harvests left because of the poor quality of the soil due to over farming, is that true?

While it is true that farming has led to a serious decline in soil quality and productivity in some parts of the world, the fact that only 65 harvests are left is not very accurate. It’s on a case by case basis. Some farms will produce more than that while others will produce less. That’s why there is serious attention drawn to how we can restore back these poor soils by taking steps in the direction of returning manure back to the soils and other measures! I hope this answers your question. You can always let me know if you need more clarification
