Why did the Wheatfield decision have such a long standing impact?

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

The Wheatfield decision had such a long-standing impact because it transcended the test of time and today we can see the consequences of climate change on the planet.

When Artist Agnes Denes presented his artwork "Wheatfield-A Confrontation" in 1982, she planted a two-acre field of grain in New York City. At the back of this field were the skyscrapers of the city.

This was meaningful because the artists tried to send the message that large urbanization, concrete, and steel, were a major risk for the soil, agriculture, and the land.  

And as we see today, she was right and the meaning is that 30 years later, climate change is a major concern on planet earth and governments are trying to reach agreements to minimize the consequences of global warming.
