Firstly, poor air quality is a hard-wired problem many countries are tackling painstakingly. Many factors have led to this conundrum. On one hand, economic development has induced many manufacturing sectors to work around the clock, irrespective of crucial environmental-friendly standards. The toxic gas they emitted has made key parameters of urban air quality plunge. On the other hand, the expansion of metropolitan areas have eroded masses of forests, wiping tress and plants from the earth. With the restorative capability of our nature impaired, the greenhouse gas vehicles, planes and machinery equipment produce have no outlets to be recycled. That's why the incidence of respiratory diseases in populated areas have soared in recent decades.

With many determinants at play, some environmental experts want to address the elephant in the room first and cut the number of commercial flights, since planes spend way more fuels than automobiles. Nevertheless, it's by no means a slam-dunk approach. In what manner should we define nonessential travel? The trend of globalization entails that people go to other nations for work, study, migratory or even cultural reasons. They have distinct purposes and meanings in people's lives and prioritizing one over the other would incur drastic opposition from flight-takers. What's more, while tourist travel might sound trivial and frivolous to environmental activists, it brings substantial income for local tourism and service industries. Once people are not granted enough freedom to visit hot tourist spots, what are the odds of these regions continue to thrive economically? Besides,limiting flights won't help reduce the rising carbon dioxide produced by automobiles. Granted that private vehicles use gas a lot less, countries and cities all over the world have far more cars than planes, and the average possession of cars per household in many developing nations have dramatically grown year on year. Even we restricted certain flights, the cumulative influence of cars on environment would still be disastrous. So turning a blind eye on the expansion of automobiles is just a placebo, not a feasible solution.

If we want to get down to the problem of air pollution, we need to adopt a forward-looking perspective. One far-reaching strategy is continuing developing energy-efficient technologies. If all types of transportation tools burn less oil, the harmful gases they release would decline tremendously. 

Next, we must safeguard the mode of sustainable development. That means all nations should be resolute in carrying out greening projects, returning forestry and unmined lands to nature. Also, If all industries in our society abide by eco-friendly regulations strictly, citizens would breathe in a lot more fresh, salubrious air in daily commutes.

To recapitulate, the limiting of air travel is just a self-deceiving palliative, rather than a cure to the worsening air quality. More sensible means should be handed down from the top, and citizens should be more environmentally-conscious to practice a low-carbon lifestyle.
