What are those but moral and/or intellectual superiority declarations? And they're false too! We historically never cared or done as much for the environment as we do right now. Cars are getting stricter pollution norms on a schedule. Home appliances are rated by efficiency, we even banned some things like traditional light bulbs. Vacuum cleaners have a maximum draw power by law! Garbage collection is more expensive if not sorted. We pump money into renewable energy. We banned plastic cups and bags and even straws. Industry besides being regulated and checked is economically incentivized to consume as little energy as possible. We have naturally protected areas and species, we regulated fishing, etc, etc. We even have some clear positive results like pollution going down in big cities compared to last century.
Maybe it's not enough right now. But it's downright dishonest to say we don't care or do. The solutions left to be found are nowhere clear or easy. We don't have infinite resources to do things, we can't force every country to do the same, change takes time, etc.
