By surveying human history, it has obviously been observed that in the past, people and their governments suffered from a lot of difficult problems such as pandemic diseases, expanded poverty and famine as well as a wide array of wars. But nowadays thanks to modernity, technology and awareness, these adverse aspects of human lives have considerably shrunk and rectified. From this perspective, I would maintain that although pay attention to safety issues in different countries should be considered, improving public health and expanding research fields by more investments from governments should not be underestimated.
