  Astrophysical observations indicate that the ``Local Universe" has a
relatively lower matter density ($\Omega_0$) than the predictions of the
standard inflation cosmology and the large-scale motions of galaxies which
provide a mean mass density to be very close to unity. In such a local
underdense region the Hubble expansion may not be representative of the global
behaviour. Utilizing an underdense sphere embedded in a flat universe as the
model of our ``Local Universe", we show that the local Hubble constant would be
1.2 -- 1.4 times larger than the global value on scale of $\sim80$ Mpc,
depending on the variation of $\Omega_0$. This may account for the recent
measurements of the unpleasantly large Hubble constant of $\sim$80 km/s/Mpc
using the Cepheid variables in the Virgo cluster and the relative distance
between Virgo and Coma cluster and removes the resulted apparent paradox of the
age of our universe.
