I'm absolutely convinced that even with 18 lanes streets or roads, in not many years time, they would be collapsed. And why? Because we humans are as we are, there's no awareness , there's no culture of responsibility respect to the environmental limits. I know there are a very big bunch of people who couldn't care less pollution. To them is not a big deal to asphalt everywhere, it's not a big deal to fragment most ecosystems. Think about that, the less cars driving the less space we need to asphalt, I don't know if you catch me. Imagine if we have so much land asphalted in Spain that if we used all that surface to produce green energy we could supply all the energy that our country needs...... Go back to think about it.
To conclude, I think asphalting a lot of land impoverishes a lot of people, in the long term, and makes rich a few ones, in the short term. We almost have the same kilometers of highways than Germany, but Germany almost doubles us in population and the worst is that some of the highways built are not justified because they are underutilised. Dear politicians, please, change your policy of asphalting, because it is bread for today and hunger for tomorrow; please drivers, think about no using so much your box of four wheels, don't be so lazy above all if you are alone in your car. Put into practice this: 4 x 4 = four wheels for four people. Thanks.
