Why are the Chinese laying iron nets in the mountains? Which surprised everyone. In fact, by doing so, they prevent mountains from being eroded. First, they put a net of iron on the sloping mountains to prevent erosion. Then, they spray hydroseeding over the net of iron, which is a mix of grass, tree, and plant seeds. Within a few days, the seeds sprout, causing the mountains to become green. This helps maintain ecological balance.
