Ask HN: Why aim for reducing climate change?
The biggest risk for climate change has always been food production and economic water availability.  Just look at the western US that depends on the Colorado River for the risk involved.<p>We can live most anywhere on the planet, and that isn&#x27;t going to change.  Though relocating from higher risk areas to lower has a cost that will be inflicted on those who are in an area where the risk shifts.  If it happens on a long enough timescale the effects won&#x27;t be that great as we&#x27;re generally rebuilding our infrastructure on regular intervals anyway.<p>I always wonder why we focus so much on prevention instead of mitigation the actual risk cases.  Instead of curbing emissions, which seems to have no effect (see economic down turns with corresponding dips in emissions as evidence with no apparent results in CO2 levels).<p>Why don&#x27;t we invest in better water distribution systems and food production resilience?  Instead of making it hip to have a lower carbon footprint, why don&#x27;t we change what being &quot;green&quot; means to, say gardening?
