You can build a trigger on the Task and Event objects and update the opportunity related to them. 
trigger updateOpportunityDescription on Task (after update)
{
	Map<Id, Task> oppIdMap = new Map<Id, Task>();
	for (Task t : trigger.new)
	{
		Id relatedId = t.WhatId;
		if (relatedId.getSObjectType().getDescribe().getName() == 'Opportunity')
		{
			oppIdMap.put(relatedId, t);
		}
	}
	if (!oppIdMap.isEmpty())
    {
		List<Opportunity> opps = [select Id from Opportunity where Id IN :oppIdMap.keySet()];
		for (Opportunity opp : opps)
		{
			opp.Description = oppIdMap.get(opp.Id).Description;
		}
		update opps;
	}
}
You can build a similar trigger on the Event object. Hope this helps.
