Children are suffering from nature-deficit disorder.

"Nature-deficit disorder is the idea that human beings, especially children, are spending less time outdoors than they have in the past and the belief that this change results in a wide range of behavioral disorders." 

Causes of nature-deficit disorder:

• Urbanization without nature.
• A culture of fear.
• Silicon faith.
• Cultural devaluing of nature.
• The post-apocalyptic view of the future. ("LAST CHILD IN THE WOODS:SAVING CHILDREN FROM NATURE-DEFICIT DISORDER" by Richard Louv, September 13, 2014.)

House of Commons Ottawa February 28, 1928 Miss Agnes Macphail (Southeast Grey) Progressive: "...This great mass of people is disappearing from the open spaces into crowded cities...Agriculture is still the main business of the Canadian people. The nation's prosperity depends on a bumper crop. The following words were used by Aristotle: 'The first attention must be paid by that which is in accordance with nature; for by nature agriculture is first, next come all those things which are derived from the earth'".

House of Commons Ottawa February 28, 1928 MP Abraham Heaps (North Winnipeg) Labour: "With regard to what my friend the mover of the amendment (Miss Macphail) has just said, I would point out to her and to the House that with respect to large, open spaces in the centre of cities, it is an experience the world over that those who benefit most in the end are those who, unfortunately are in limited circumstances and who as a consequence are precluded from having the enjoyment of homes and grounds such as those more well-to-do are able to afford."

"They are the ones who perhaps more than others derive the major benefit of the large parks in the great cities. At the rate at which development is taking place in Ottawa, I am confident that it will not be long before this city will become congested in the matter of population, and I do not hesitate to say that the ones who more than any others will appreciate what this Parliament is doing day-to-day are the mothers of little children who will find it possible to enjoy advantages for their families in this way ."
