I think that both of these causes represent driving forces behind science inquiry because they represent considerable challenges causing much in the way of consternation. Global warming has incredible implications for the planet that cannot be ignored. With so much at stake in the global warming paradigm, science feels compelled to address these topics as quickly as possible. At the same time, cancer research also holds similarly challenging implications for so many. The idea behind needing to find cures to both or some type of redress for both is driven by how many lives are impacted by both.
Global warming is a current issue that science is addressing. The evidence of the damage caused by global warming has been identified and recorded by scientists through-out the world. Recently different nations came together in Copenhagen to discuss the problems that global warming has caused and is expected to cause if it continuous to occur. Scientists agreed that they must work together and independently to help stop and reverse the effects of global warming.
Cancer research began as scientists were able to have more intricate methods for studying and analyzing the movement of cancerous cells in the human body. An indication of sciences involvement in finding methods to cure and prevent cancer are touted by the media. For a person to find proof of the research, outcomes of the current research, and the effects on the continued research in the field of cancer, one only needs to run a search over the Internet, watch news programs, and look through magazines.
I would choose both of these topics because there is recent evidence to prove that scientists are currently working on these issues.
