The quality and average count of efficiency is low in China of which fails to enhance manpower’s production without the introduction of comprehensive transformation in the fields of agricultural production pertinent to tech-based approaches.
Video is poorly documented and researched. I have lived in both US and Canada. Both countries have huge amount of flat land suitable for agriculture. This isn't the case in China. Because these countries have low farming population, they have to rely on machinery which isn't the case in China either. I do believe US and Canada have better agriculture technology. However, the video's claim didn't reference any stats on agriculture efficiency.
