First of all, while human civilisation has made great strides and reached advancement never before thought possible, it still needs to respect the Mother Nature. We have forgotten how much we are at the mercy of nature. The rapid contagion of and destruction by the novel coronavirus show us how vulnerable we ultimately still are. We should of course be thankful that this coronavirus is not particularly deadly. But the fact remains that Covid-19 bears with it a wake-up call for human beings on how we should live, and how our technological progress means little if it only serves as the tool of an environmentally exploitative status quo.
Secondly, a correct response is everything. Countries that view the threat seriously and responded with quick and decisive action have been more able to cope with the virus attack and bring down the fatality rate. China and South Korea are the best examples. On the other hand, the US and many European countries are examples to avoid. Fortunately, the virus has yet to attack developing countries with a huge population and poor healthcare facilities in a serious manner.
Last but not least, we are all on this planet together. Despite the seemingly impenetrable barriers of our own little lives, we are not immune to something that is happening thousands of miles away. We must find a way to move forward as one, or we will all go down with this ship.
