exploring the world around you can be such a wonder

I agree!   I always feel such a deep sense of peace and contentment when I'm in nature. 

So what is it about nature?

It offers a diverse display of colors, sights and sounds; uncertainty; multisensory qualities; and above all, aliveness, Van Wieren said. Nature is usually in a state of flux, which fosters problem-solving opportunities that build self-confidence.

But we could be in trouble if kids continue their technology habits, she said.

“This is the first generation that’s significantly plugged in to a different extent and so what does this mean?” Van Wieren said. “Modern life has created a distance between humans and nature that now we’re realizing isn’t good in a whole host of ways. So it’s a scary question: How will this affect our children and how are we going to respond?”

I'm guessing that kids don't even have to go deep into nature.

They just need to be outside more.
