The biggest Problem around the world
Today, there are many issues around the world such as social, economical and environmental problems. However, from my point of view, I think that the most important issue is scientific research. If we develop scientific and technological investigation, we will be able to deal with problems related with food, diseases and the environment. First of all, we can improve the harvest from crops by using new technologies. For example, the transgenic crops can produce a huge quantity of fruit. Second, scientific research helps us to discover new medicines, which can control dangerous diseases. Also, the problem about the hole in the ozone layer was discovered by scientific research. Mario Molina, a chemical researcher, won the Nobel award by his investigations about this problem. In conclusion, it is necessary to do scientific investigation because it helps to solve many problems around the world.
