I think reducing CO2 is no need but reducing number of using fossil fuel is needed. It’s because we have to take a notice to more essential problem than invalid global warming issues.
In the same way, stopping killing kinds of whales is no need but keeping the ecological system safe is needed. It’s because we have to remember we are the member of the ecological system. It means we must not protect specific animals except some endangered species caused by human. I feel this idea criticize the capitalism and human’s ego.
