I'm against the greens because they are really neither here nor there. Ever since the Industrial Revolution, the state of the economy is almost a reflection of the production of waste. The greater the growth, the more damage is done to the environment. Similarly, a rapid population ascent would indicate that more waste will be produced as a result of more resource being consumed.
The Greens know this. Nonetheless, they choose to sacrifice this aspect in order to appear more acceptable to capitalist politics. Environmental protection is quite the opposite to economic growth. There is no such thing as a middle ground. Until they actually sit down and accept the nature of their system, I would just continue referring to them as one of Labor's whipping boys.
