text: "Does your expression in the mirror suggest an emotion?" Maybe if you're looking at yourself in the mirror and you're feeling sad maybe you can see it in your face because its actually you feeling sad. But someone really doesnt know just by the face just you cause its you. And its the same for technology they really cant tell what your emotion is just by looking at you. unless you're really happy and sometimes you can actually show an emotion inside and out and if your computer can tell an actual emotion thats true well maybe because you really are feeling happy, sad, Etc. So I believe that technogly really cont tell someones emotions.     Most countries around the world share the same global problem; air pollution.  Cities like in Germany, France, and America suffer with air pollution.  All this smog comes from the cars people drive on a daily basis.  But now, people have decided to make a change to that.  All around the world, cities have been banning the use of cars or just taking a day off from them.  Doing this has made a huge change to how these people treat their air.
