Are jains allowed to use things that are underground, like a metro or a basement parking

Jain philosophy emphasizes non-violence (ahimsa) to all living beings, including microscopic life forms that may reside underground. While Jain monks and laypersons are extremely careful to avoid direct harm to life forms, the use of underground infrastructure such as metros or basement parking is not explicitly forbidden. The primary concern is minimizing harm, so many Jains might consciously avoid actions that could kill or injure subterranean life, but practical daily life often necessitates the use of such facilities.
