There is a growing body of evidence that nature is important for our health. Spending unstructured time playing in wild places enhances attention, combats obesity, reduces stress, and can remedy anxiety, depression, OCD and other mood disorders. This is true for every age, but it's especially true for our children, whose bodies and minds are developing. There is a growing crisis of nature deficit in our culture - we are spending too much time in front of glowing screens and not enough time catching glowing fireflies.
We need to raise a generation that cares for the planet, so we must teach our kids to love the nature around them. How can they grow up to care about forests if they don't even know the local trees? How will they know what clean water is if they have never held a frog, or watched a fish catch a mayfly?
