There is general consensus among the scientific community that human activity is at least partially responsible for climate change. However, assuming we don't know for sure, isn't it better to take action now? If we are to blame, our action will abate climate change. If it is just natural fluctuations, we're not really losing anything.
Yes we are losing something... billions and billions of dollars, pushing ourselves even faster into 3rd world status. Do you really want to risk that?
You can't just say
"assuming we don't know for sure, isn't it better to take action now?" I've heard grass could damage the environment... some people regard certain types of grass as a
weed!
Now of course we are not quite sure which are causing damage, or even if damage is really being done but isn't it better to take action
now?
From now on I declare that NZ shall be
grass-free!

I understand some people will moan and complain about that, as apparently they think grass is needed for their business?!
So for them I've came up with the GTS (Grass Trading Scheme), it is all very complex involving grass credits and research funding for grass substitutes but a rough rule of thumb is you can expect to pay a yearly tax of NZ$1 per blade of grass.
Thanks folks, and think of the good for the planet Earth!

The ETS requires producers to pay for the cost of the pollutants they produce. Through this, it is economically worthwhile to utilise more environmentally friendly methods of production etc. Without this, producers are effectively encouraged to use cheaper, more environmetally damaging methods. The money paid goes to offset the damage done, by planting trees or whatever.
It is only "damage" and "pollutants" if you fully buy in to the idea of global warming in the first place...
