I understand your point, but this is no time for sobbing pessimism. This might just be our last hope. WORK LIKE HELL!
Will work like hell, but a half century of relentless data sais the status quo will continue. That does not mean that I do not have a positive attitude, and will continue to contribute and work towards positive change. I simpy have no more naievity left in my soul to believe it will actually make a difference until I actually witness positive results
