Last fifty years,every nation saw an exponential increase on traffic along with a lot of pollution problems.many people hold the perception that increasing the price of petrol is the best way,however,whether this makes sense is really a contentious one.while there are certainly valid argument to the question,i personally believe that the growth in price only won't prove effective!first of all,it is of vital importance that the increase cannot determine and stop our environment from being polluted.given that an individual can afford a car,the price of petrol is such a tiny thing which can be ignored.it seems that everybody can shoulder the little increase.another major contributing factor is the mind people hold.as we can imagine,once the awareness will be improved,all the problems become easy.in order to resolve this issue,i believe we must first address its root causes.at the heart of the matter is the energy we use now.i firmly convince that we should explore alternative resources to take place the oil.
we use now.government should invest in the researching programs such as solar energy and wind energy.as we can imagine,inthe future,more and more petrol-run cars will be replaced by solar or wind ones.in reality,of course,i believe that this is really a problem of such complexity that no effect solution is likely in the short term.however i can convince that the measure outlined above would constitute a good step.
