Green Parties - What's their future?

Are the Green Parties doing too little too late? Have they shrunk from telling the voters the full extent of the bad news because it's electorally unappealling? Or has their time come at last? The former leader of the Green Party of Malta, Harry Vassallo, has  a background with green politics in the European Union. Also a human rights and animal rights lawyer , he's well qualified to give us a Green overview and to answer key questions: Was it a mistake for the Greens to engage in the parliamentary process, rather than to remain apolitical activists lobbying all parties for the urgent changes that are long overdue? Might this have been a more successful means of giving the public the unvarnished ecological truths?
