Governments should spend money on railways rather than roads. To what extent do you agree or disagree with this statement?
Governments should start investing more funds in building more railway infrastructure rather than roadways. Roadways and cars contribute to a very substantial amount of global warming and deforestation. It also causes the demolishment of people's property. Railways, on the other hand, are an eco-friendly mode of transport and can offer better connectivity and faster access to areas. This essay extremely agrees that governments should construct more railways.
