I think floods are less expensive than other natural disasters like hurricanes or earthquakes. Depends on intensity as well, probably.
Floods are very localized, which means that one area can be severely affected while an area just a few miles away is fine, the natural disasters that have the most destructive potential are solar flares and volcanic eruptions, solar flares can affect and destroy our technology and if we ever received a huge one we could be sent to the eighteenth century in a matter of days, volcanic eruptions can be incredibly damaging as well with all the material they release to the air as it can block some of the sunlight and reduce the temperature of the whole world by several degrees and affect our food supply for years or even decades.
I'm not saying that flooding is not a bad thing, but handling it is not as difficult as when dealing with a volcanic eruption. The impact of flooding is
only limited to certain areas and rescue of flood victims can be carried out as soon as possible. Moreover, the recovery from the flood disaster is
also much faster and usually the death toll is not too many. In contrast to volcanic eruptions, the atmosphere is very tense with polluted air and
if there are residential residents it is more difficult to rescue them. The death toll is also quite high, so dealing with volcanic eruptions is indeed
much more difficult. The effect can be very large, the smoke from the volcanic eruption can spread even to very far areas.
Actually, any disaster that occurs is a disaster for human life, and should be used as a lesson for humans to take care of the environment better.
Most of the natural disasters that occur in this world, because of man himself. So hopefully the natural disasters that occur will be a warning to
all of us, so as not to damage our environment. Taking care of nature is not only the duty of the government, but it is the responsibility of all of us.
Let's start doing small things to protect nature , such as not littering, use more environmentally friendly products and reduce the use of vehicles
that use fuel oil. If we can contribute in protecting our nature, natural disasters will not happen much.
