The H1N1 Flu virus killed more than 50 million people, Ebola killed more than 13,500 people and during the ongoing Coronavirus pandemic, Covid-19 is close to killing more than 200,000 people worldwide. It looks like viruses are the true enemy of the human race. So have you ever sat down and wondered what would happen if all viruses disappeared today? We all know the benefits of that… But what are the disadvantages if something like that ever happens? Watch On YouTube Ideally, viruses and bacteria have both positive and negative impacts on the ecosystem. Let’s take an example of the ongoing Coronavirus pandemic. Yes it’s dangerous for our health and economy. But because of it the pollution levels are dropping drastically. Ozone layers are healing and so many wildlife animals are back to their normal lifestyle. Viruses are responsible for killing about 30% of ocean bacteria daily. Hence, viruses play a considerable role in the production of oxygen and removal of carbon dioxide in the atmosphere. Therefore, by killing bacteria every day, viruses are responsible for generating about 150 gigatonnes of carbon flux every year. Some viruses are also vital in facilitating the process of photosynthesis. Viruses directly impact the global cycle of both oxygen and carbon. Those two are the main elements that affect life. Removing viruses entirely can significantly affect the ecosystem by causing enormous carbon and hydrological cycles. As we experience immense, oxygen, and carbon dioxide concentrations, large scale extinction can be experienced as the world tries to gain equilibrium. I know it’s gonna sound weird… but deadly diseases caused by viruses also help in controlling the population on our planet. If the population starts growing rapidly, then the world will start facing many uncontrollable problems economically and environmentally. We do not completely know what other things would happen because we have never experienced such a scenario before. However, based on research and the documented knowledge, if viruses disappear from the face of the earth completely, the long term effect of that will be a lot more scary and dangerous.
