This kind of problem could take hours for the exporters to export their goods to other places like the market, malls, and other cities along the country. And due to that kind of problem may lead to poor source of income for the exporters, for when the exported product reaches their destinations chances may, that some of those are already rotten.

One of the most exported goods in the Philippines is the countries very own national fruit, mango (Mangifera indica). Mango is a sweet fruit and succulent that’s why Filipinos just love to eat the fruit, but unfortunately it is not that cheap and buyers have to save, causing the fruits to be stocked and slowly by slowly rot and making the buyers refrain from buying.

Another thing is people now a day’s tends to throw things that can still be recycled, and recycling is something that could lessen up the countries waste management. The Philippines for example is full of wastes, some citizens just don’t know how to recycle.
