Evolution has taken off many traits from the human psyche, but the remnants of some are still holding a bit too strongly considering the current times, particularly the tendency to stock pile for coming emergencies. Currently, this has translated into buying sprees and subsequent hoarding that people have dived face front into across the world.
Panic buying of products has become a widespread disease of its own, resulting in verbal outbursts and occasional physical altercations even in the most developed of countries. Before stocking up on products think of what you are buying. Perishable goods like fruits and vegetables will only rot away. And products like salt, sugar, rice, flour, lentils and such will keep for months. It is the same for root vegetables like potatoes and carrots; when stored in a cool and dry place, these can be stored for a few months. As for meats, poultry and fish, these can be frozen at home and kept for well over three months.
This also give sellers the power to hike up the price of essentials. This is easily seen with the case of face masks, hand sanitisers and washes, as well as for daily medications. Considering where sellers in the country hike up prices for any and all occasions, there is no reason to give them one more scope of exploitation. Buying up like this leaves little to nothing for the others in the community, showing inconsideration and apathy, which is the last thing one needs at times of great emergencies. Dissipating community harmony, and cultivating animosity towards each other is not at all welcome in times like this.
While there is reason to be sensible and stock accordingly, the common sense to go with it disappears. Carefully consider what you need, and keep safe and healthy.
