Environment problems have become increasingly popularsevere in many parts of the word today.
First of all, environmental problem is the issue of such complexity that no single solution is likely to have a phenomenal influence on it.
Environmental problems involve such complex combinations of factors that no single solution can solve them completely.
Rather than introducingputting legislations toon limit using flights, I feel that people should move attention onpay more attention to more effective ways to reduce the atmospheric concentration of carbon dioxide such as planting more trees or exploiting clean energy sources.
Secondly, I would contend suggestions like encourage people to use more cars to alleviate hothouse gases emission is totally misleading. Even if cars consume less fossil fuel than flights, the uncontrolled numbers of vehicles will cause more problems (e.g. traffic congestion, road accidents etc.). Moreover, more cars mean more infrastructures need to be done by governments. Of course, this will add a huge financial burden on countries.
I think your reasoning is misleading, too. There's no encouragement of using more cars as a way to protect the environment. Driving cars is also blamed for producing greenhouse gases too! That's why the trend now is to promote public transportation. Flights can not be replaced by cars. The topic using this comparison is simply to get the feeling that flights are really energy-consuming.
In addition, there is no proper (persuasive) definition toofdefine non essential flights.
Great point :)
In conclusion, I reaffirm my position that traveltraveling by plane should not be constrained. Even though there are some negative impacts on the environment,I think they would be insignificant when comparecomparing with its role in promoting the world economy and cultural interaction.
Hope this help:)
