Many groups have been included, or at least mentioned, in the quest for restoration of our world.  I know of one that may prove to be the most resistant to change, and that is the inner-city "hip-hop" culture. 

As far as my experience with the culture and its music goes, their prime directive is to acquire wealth and status at all costs.  The symbolism is pervasive, as is the evidence of excess.  The massive jewelry, the massive customized vehicles and the massive arsenals of each neighborhood kingpin show a complete disregard for the outside world, because to them their neighborhood is all the world.  Nearly every rap song is a treatise on money, power, and neighborhood respect.  They live and die by their colors, by the law of the streets.  Global warming would be regarded with not much more than a "What you say?" and a derisive snort. 

There is absolutely no connection to nature and its message.  Why would they care?  How would it threaten their respect and their 'hood?  Hollywood has made numerous attempts at informing the popular culture with movies about ecological disaster and climate shift, but the gangbangers, the dope slingers, and the pimps could care less.  They are a tough nut to crack, but crack that nut we must, or we will not see the massive grassroots effort that must surely take place reach all corners of society.

One could begin with the music.  Inject responsibility into their lyrics and one may see the beginnings of a shift toward stewardship.  Another approach would be to send in awareness groups to educate in the schools and encourage participation at young ages.  Proverbs says "Train a child when he is young, and when he is a man he will not stray from it."  Some have grown up in the gangs, so to reach them would take a herculean effort at appealing to their culture. 

But no matter the approach, today the greatest challenge at the grassroots level is the inner-city culture.  One must encourage them to participate, or else see the same stagnation at all levels.
