Is prevention of vehicular pollution better than cure?
Yes! That is why we should kill off one third of the world's population and sterilise another third. Any other methods are hopelessly inadequate and do not get to the root of the problem - too many retarded people infesting the planet.
Reply:Prevention of anything is better than having to find a cure for whatever problems it caused.. So yes of course. Cure, I will assume you mean trying to cure illness that is result of pollution? Or do you mean try to cure the pollution problem after it has already gotten out of hand? Either way, prevention is always the best..
