Why do so many people focus on climate change rather than respecting the biosphere, which includes stopping climate change? I think the answer is quite obvious. Climate change is a proxy variable for biospheric degradation that fits into the rubric of optimizing single variables via our capitalistic, destructive way of solving problems.
If people focus on climate change, they can advocate for creating new technologies such as solar power and wind, which nicely fits into making profits from new economic sectors. If we instead aimed for respect for nature, then it would be much harder to claim that green energy is a solution because it is also destructive and requires massive amounts of mining to sustain. Moreover, our current and rising levels of energy usage are so high for one reason: to promote further destructive practices such as extracting materials from the earth to sustain unsustainable consumerism.
Proposing climate change as the main problem allows politicians to talk about CO2 and credits for electric cars. Respecting the biosphere means way less cars. Making climate change the issue allows companies to claim their building is green. Respect for the environment would mean an end to many of those companies. Stopping climate change means transitioning to solar panels made with destructive practices in China. Respect for the biosphere means using much less energy altogether.
In short, the term climate change, while valid and useful for highlighting a specific problem, is not the problem. The problem is a lack of respect for our biosphere, and until we develop that respect, we will never get anywhere.
