I envison a world where children are able to wander around the world without parent's needing, or being told, that they need to follow with an antibacterial hand wipe. As long as what they're touching is not truly dangerous then children should be allowed to be exposed to the world and the germs around them. I value health as a whole, mental and physical. I know that explloring nature is not only good for your mind but interacting with different animals and plants can be very beneficial for children's immune systems. A possible intervention would be to spread awareness about the benefits of allowing children to play (and maybe eat) with dirt, this could happen through a public health outreach campaign where posters, billboards, bus signs etc. are spread around cities and parks to help educate families.
