Translation of umweltbewusst

for a minute I blamed the burger that I had eaten at the duty free back in Cancun, but thinking a little further I recalled eating street food the night earlier, as it was Mexican independence day.
How could I get better in Spanish if I had to eat by myself. Impossible. The next days we always ate together and sat around the table for hours discussing politics and the lives we were living.
In the evening we saw a Dutch couple which we have met in El Calafate (in the Perito Moreno tour and who were with us on the airplane to the Peninsula). We looked for our hotel and it was OK.
