They are arguing about whether companies should pay when they put carbon pollution in the air. Proponents say that it's simple economics -- if it's free to pollute, you'll get a lot of pollution. Opponents claim it will raise the cost of energy that's produced from high carbon sources, like coal. But here's the secret that most people seem to be missing: There already is a price on carbon, and it's paid by the taxpayers. Carbon pollution, like every other form of pollution, has an impact on the environment. Throwing waste into a river will cause the fish to die and the people who drink the water to get sick. And when you produce carbon pollution, you get climate change -- sea level rise, stronger storms, severe droughts, damage to agriculture, and more. All of those impacts cost money. Insurance rates go up when storms get more destructive. Taxes increase when cities have to rebuild bridges and roads. Military budgets go up when droughts and population changes cause conflicts. Not to mention impacts on agriculture and health care costs. In other words, the price on carbon is what we all pay when there is no market force to limit the pollution that causes climate change. So the debate is really about who will pay that price -- the companies who are making a profit from the fossil fuels, or the taxpayers who pick up the cost now? Right now, we have private profit and public cost. It's just like if we allowed every business to throw its garbage in the street because it's too expensive to have it moved away properly. Does it add a little bit to your dinner check to require that restaurants dispose of their trash properly? Sure. But it would be more expensive for you if the city had to clean the streets of their garbage every day. So just like we put a "price on garbage" we need a "price on carbon pollution." Now, a "price on carbon pollution" can mean a lot of things. You could tax companies based on the amount of...

However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face. Question: The fact that some people are afraid of looking in the mirror reflects that _ . - they suffer from metal disease - they treat life in a negative way - they are too ugly - they can't bear the pressure of being old
they treat life in a negative way
