Clean like Vancouver

Vancouver is really a paradise. It has got everything as a package like a sea, forest, lake etc. Our last trip to Vancouver was the best. The view is breathtaking. The nature and the coastal city all in one province. I wonder how hard it is to maintain a clean city like this.
We arrived on a Saturday morning and stayed in Vancouver in a hostel accommodation ( ). The next day we visited the coasts and ports. The evening we decided to camp in the forest which was the most exciting part. It was so beautiful that you will wanna live your entire life in the forest without anyone. It makes you believe in nature.
