Why is helium a problem?

Could you please elaborate on the issue of helium being a problem? Could you explain the reasons behind this assertion? What specific factors contribute to helium being considered problematic? Is it due to its scarcity, environmental impact, or something else entirely? Could you also discuss the potential consequences of this issue and any possible solutions that might be explored to address it? I'm particularly interested in understanding the underlying reasons and potential impacts of helium being a problem.
