Smoking is responsible for many health problems. Should it be made illegal? Most of the people would agree with this statement: Consumation of tobacco has very bad consequences to the human health. The question to be considerered is: should it be prohibited by the Government? Can the government do it without affecting personal freedom? First of all, smoking is the main cause of an important and severe sickness, the lung cancer. A high percentage of smokers can suffer from this illness, its treatment is very expensive and the life expectancy is very low. Furthermore, lung cancer is not the only sickness that smokers could get. Secondly, smokers are not the only ones affected by tabacco consumption People who are around them, passive smokers, suffer the consequences too. Most of the time they are breathing an air around them which is polluted and this situation can be harmful for their health. In conclusion, smoking should be prohibited only in public spaces (hospitals, schools, indoors, ...etc) as well as in the presence of children, sick people and pregnant women. However, it should be allowed in open and/or private spaces.

Testing on animals is a standard in scientific research. What is the best way to deal with problem? Scientific reserchers needs making experiments in order to achive its goals. According to the rules of an advanced society, the question to consider is: Are humans more valuable than animals? What of both things (avoiding the animal suffer or developing the scientific knowlodge) is the more priority one? First of all, a modern society should show respect for the animals, avoiding their suffer, because this is the behavior of modern and civilized societies. However, animals don´t have the same rights than humans, and it could be very useful to create an ethical code which analizes and stablish what are the best practices using animals in the laboratories. Second of all, last time the alternative research tools have been developed deeply, especially the simulation models by computing. That means there are a lot of research experiments which can be made using mathematic models, instead of sacrificing living being. Despite of that, the most of the medical research, for example previous to validation a new medecine, needs to be tasted previosly in animals and as far as I know this one is the only way to try out the future solutions for our current diseases. In conclusión, the mos important priority should be developing new medecines through scientific research, provinded that those kind of practices avoid the unneccesary animal suffer. The development of new kind of research tools without animal and the creation of an ethical dode (common an consensual) could be some of the keys to solving this situation.
