Iwould like to live in the country. the advantages of living in the country are a pure/clean air, a lot of plant around you, animals around you, which walk absolutely freely, and many other advantages. the main ecological problem in the place where i live is the pollution of air. yes, my friend and i care about ecological problems, because we want to live in the clean world and breathe fresh clean air. yes, i've taken part in ecological projects at school. don't be lazy and start doing anything for the environment.
