The cold winds from Central Asia would enter India freely, making the climate much colder and drier. Many rivers like the Ganga, Yamuna, and Brahmaputra might not exist because these rivers originate from the Himalayan glaciers. Without the Himalayas, there would be less rainfall, fewer forests, and farming would become difficult in many regions. The northern plains might even look like deserts.
