Is it possible for developed countries to sustain present standards of living? 

The future is often hard to predict; depending on what we are, the answers may well vary, and they all make sense, but in my view, it is possible for developed countries to sustain current standards of living for the time being. Now let me explain the details.     

First, modern technology and ínfrastructure help the countries maintain their standard of living. For example, genetic engineering has boosted agricultural production. Plus, thanks to efficient transportation and renewables, people consume less resources. So, it is unlikely that economic, energy, or food crises will threaten the people in the near future.     

Next, I understand some may argue that we should lower the current standard of living, but people are making efforts to maintain their current lifestyle, by practicing “sustainable consumption,” such as reducing, reusing, and recycling. This balance between “economic growth” and “sustainability” is important, so the UN Sustainable Development Goals is working toward achieving both.           

Therefore, even though challenges remain, we should be optimistic about maintaining the current standard of living, and finding ways to sustain it for longer. Thank you for your attention. [182 Words Type-O]
