Creo que la contaminación del aire es un problema que se tiene que resolver muy pronto. Cada día hay más carros que contaminan el aire que nosotros respiramos. Además, la deforestación en las regiones cerca de la ciudad elimina una gran parte del oxígeno que los árboles le proveían (provided) a la población de la ciudad. Es importante mejorar las condiciones de las calles para que las personas puedan pasear en bicicleta para ir al trabajo. Así, todos pueden conservar el petróleo, que es un recurso que no va a durar (last). El uso de bicicletas en la ciudad es una de las mejores ideas para recurso natural el uso de los carros. Debemos dejar de pensar que el carro es un objeto necesario, y buscar otras maneras de transportarnos. Quizás algún día podamos resolver los problemas que nos causa la contaminación.
