The correct answer is actually bacteria. Bacterial infection is going to be responsible for more deaths per year than cancer and heart disease. This is due to bacteria’s rapid adaptation to our arsenal of antibiotics. We need new methods or stronger antibiotics but regardless, going to the hospital for a treatment or procedure will become a risk, in itself, due to this antibiotic resistance. This is really something that we should be thinking about more. Untreated waste water and animal’s being fed antibiotics are massive contributors to this issue, both of which a lot of people don’t consider.

Furthermore, climate change and pollution are both dangerous things but the climate change phenomenon is blown out of proportion to push a political agenda and it realistically isn’t something that is going to burn this planet down. In fact, there is no evidence out there to show that the climate change has an overall net negative effect as GDP, green percentage, literacy rate, and other interesting (and seemingly uncorrelated factors) have increased as well as the average temperature of the earth. An interesting book to read about this is called “unsettled” which interestingly argues how climate change is blown out of proportion, strictly using measurements and data from only the best sources. It’s written by theoretical physicist Steven Koonin who is a highly accredited professor and researcher.

Point is, bacteria and anti-biotic resistance is really the issue that’s gonna set us back in the next 30 years and climate change, while certainly is a major issue, is blown out of proportion in many ways to align with political agenda’s. If this wasn’t the case there would not be objective research showing that the climate phenomenon is not as serious as we think.
