You could ask the same question to the people who think the environment is very important but don't seem to care about how their electric car or its Lithium ion batteries are mined or manufactured. So long as it's not in their back yard it is out of sight out of mind. And if they overload the regulations so that there is no local manufacturing and it's all imported from countries with poor environmental controls, they are effectively exporting all the pollution to poor people in China
