Say no by saying yes.

"...Leave your windows and go out, people of the world,
go into the streets, go into the fields, go into the woods
and along the streams. Go together, go alone.
Say no to the Lords of War which is Money
which is Fire. Say no by saying yes
to the air, to the earth, to the trees,
yes to the grasses, to the rivers, to the birds
and the animals and every living thing, yes
to the small houses, yes to the children. Yes."
Wendell Berry - Look out
