Earthquakes, tsunami and many other natural catasthrophes have a detrimental impact on unwealthy nations. Some people consider that G7 and other richer nations should help them, while others think that they should not. From my opinion, I believe that sharing aid for damaged nations is crucial.
Firstly, it is very hard for government with low GDP to sustain their regular life, and combined with unseen disasters may lead to greater losses. Consequently, these nations might lose their buildings, culture and people. In Morocco, for instance, after lots of earthquakes they lost building, food and citizens, and with help from other countries they recovered faster. Morocco spent that money on rebuilding houses, hospitals and schools, also, it helped to ensure safety of citizens by creating safe zones.
Secondly, aid from countries are strenghten relationships between countries. If one nation gets aid from another country they develop more better and advance union. Nations can trade with products, food and materials at better price that will have significant impact in the future. In Uzbekistan, for example, after 7-9 magnitude earthquakes, which caused to enormous losses, countries from Soviet Union and others assisted them financially and some countries even sent workers. After, they developed crucial relationships that still exist today.
Taking all these points into consideration, from my opinion I consider that countries with more sustainable and better life should help poorer countries, because it will help unwealthy nations to recover quicker, and it will build relationships between them that will eventually help both of them.
