I think that people maybe just have a little compassion-fatigue, there seems to be a 'day' for everything now. It's a little like over here, on the major sporting occasions there is often a minute's silence in memory of someone who has died or some tragic event which has occurred.
This is a great thing and I agree with it... at first everybody was moved by it, except that now they seem to have it every week. Don't want to sound callous but it does dilute the impact....
Over a billion people participated in recent years so it seems some people do. Much as I care about the environment responsible care for it is something done everyday not just one so personaly not particularly.
I will attend a huge interfaith action meeting advocating for storm water jobs/green jobs in Washington, DC. About one thousand of us representing all denominations will rally to hold our elected officials accountable to providing funds for jobs that promote a Green City.
