Translation of biodiversity in German

All travel agents, but one, were all pritty unreliable as one could perceive immediately. We did not care for a dollar more or less and everybody promised the same which was not convincing.
We had dinner in a Chinese restaurant not far from where we slept, but it was not good at all. We walked home and slept early. The coming morning we were picked up on the backpackers' street.
We left town and drove around the lake. Around 30 minutes after leaving we had a flat tire, which I changed immediately. That was very annoying as the rental company asked us to fix the flat tire.
