Article 19 of the Leaders’ Communiqué from the conference read:
We support strong and effective action to address climate change. Consistent with the United Nations Framework Convention on Climate Change (UNFCCC) and its agreed outcomes, our actions will support sustainable development, economic growth, and certainty for business and investment. We will work together to adopt successfully a protocol, another legal instrument or an agreed outcome with legal force under the UNFCCC that is applicable to all parties at the 21st Conference of the Parties (COP21) in Paris in 2015. We encourage parties that are ready to communicate their intended nationally determined contributions well in advance of COP21 (by the first quarter of 2015 for those parties ready to do so). We reaffirm our support for mobilising finance for adaptation and mitigation, such as the Green Climate Fund.Very good stuff indeed—if, of course, it translates into action. But notice in the second sentence "our actions will support ... economic growth." This deals with the second great threat: resource depletion. We cannot have the "sustainable development" the communiqué promises if we continue to exhaust the planet's resources faster than it can replenish them, and that unfortunately is exactly what we are doing. We are now well beyond the Earth's ability to satisfy our demands upon it.
Growth, in the sense the G-20 uses it, i.e. GDP growth, must stop or we will suck our planet dry. Yet, what is the conversation about growth among the world's leaders? More of it. While they have at least recognized the threat of climate change, even if they aren't doing nearly enough about it, they seem to be completely oblivious to the threat of resource depletion. Tragically, our leaders do not seem ready yet to fully accept the inevitable consequences of our profligate ways.
