I Almost agree with Melania here:

from the article:
Melania Trump talked with patients and their families about “how the gift of nature and the beauties of the outdoors can contribute to the healing process,” according to the hospital.(snip)

I do know the healing benefits of nature. Our local hospital, built within the last 10 years, took this into consideration when building and the entire back part of the hospital faces natural space for the patients to enjoy while there. The morning I left there after my gallbladder surgery I watched a deer from my hospital window.

And I do know the healing powers of the cannabis plant. I have also seen many moving stories of how it has helped children with seizure disorders. That is straight from nature.

BUT...

The best thing we can do for the health of children now and in the future is to ensure that they have clean water, a food supply free of the overuse of pesticides and that the air they breathe has the lowest levels of pollution. The choice of her husband for the head of the EPA does not seem to feel any of that is necessary.

So, while i think it is nice of Melania to take her time and visit this children's hospital, I hope she can see and understand what her husbands policies are setting up for the children now and in the future.
