Absolutely correct! That would be truly mesmerizing if each of us engage ourselves and our families to sit in the garden and have some good time and evolve and enhance the nature in our homes by planting trees and plants. Mostly nowadays people are just destroying nature and using them for there own needs, infact yesterday when I was going out I saw on the road a man who was cutting those huge trees which are planted in between the lanes and that was so depressing. I think engagement in our homes and in many societies is indeed important to save nature and trees.
I feel they should design living cities and suburbs in ways that maximise greenspace. If people spent more time with trees and plants, they would like the world a bit more.
