Abolish moon sighting committee
Alternatively, as a Muslim ummah we may follow the dates announced by the Kingdom of Saudi Arabia. After all we do not disagree for Hajj dates which is accepted by whole world as one particular date announced by KSA.
However, I would personally recommend to adopt the scientific data to be obtained from the astronomical science because we are not religiously bound for "sighting" the moon which may not be seen for days together due to clouds or inclement weather, but we are interested in its "appearance" on the horizon on the first day of the moon month. I would invite more ideas to change the present dubious system.
