Something we noticed in both China and Mexico was an apparent misunderstanding of trash. In both Mexico and in China we saw paid workers sweeping up leaves in the street (China) and sweeping leaves on our patio (Mexico) then diligently placing these natural leaves in a nearby trash receptacle. Also, in both instances you could count on seeing a large pile of real trash very nearby being ignored. Neither country has yet developed a noticeable regard for the environment and keeping it clean. If one wanted to, I am 100 percent confident a similar trash pile could be found in the States. However, one difference is that it is not at all unusual to see government paid workers in the States walking along a highway cleaning it up. Also, sections of highway are auctioned off in a joint venture between the paying public or corporations and the government for clean up. Kramer on Seinfeld bought such a section of highway and carried the cleanliness a bit too far. I clearly do not understand the many hurdles these poorer countries are facing and I have no solution for this situation. As a new world traveler, I am only pointing this out as something I noticed. Both countries’ citizens were interested in us and helpful in every way, that is just harder to capture by the camera.
