In many countries people are living in a throwaway society where things are used for a short time and thrown away What are the causes of this and what problems does it lead to

To follow a socialized world like today, throwing away old things and replacing them by the new ones like becoming a trending trend, year after year they don’t decrease but become hotter than ever.
Suppose an iphone 12 is released even though it has not been opened for sale, but it has been pre – ordered for up to a month since the promotional image was released, but a time later when the promotional image of the iphone 13 comes to the market, it is normal to throw away the old phone in order to own a new phone and the throw away of technology goods becomes more and more. And with today's era, it's even more popular to choose to buy goods cheap that are suitable for your wallet and not every cheap item is a good one, it is often said that 'the cheaper the product, the worse the quality'.
Short time usage products can cause severe problems to the environment, because it is obvious that such things are made with low quality raw materials. For instance, use and throw plastic toys are made with degraded quality plastic, which will have a severe dent on global ecosystem. Or buying and buying those poor quality items over and over again affects your wallet and your health.
So it's condemnable to use everything in a short time and then throw it away, and need to take measures to overcome the unfortunate things that happen. Avoid overuse and draining of funds
