Just as human activity is upsetting Earth's carbon cycle, our actions are altering the water cycle.

Architects create spaces that accommodate human activity.

There are some that feel like human activity is the cause for carbon emissions, and because of that, we need to revert to where we were in the 1870s for carbon emissions. I just choose to disagree with that.

Storytelling is the essential human activity. The harder the situation, the more essential it is.

Incompetence is a better explanation than conspiracy in most human activity.

I fight to embrace the entire circle of human activity to the full extent of my ability.
