All our actions locally impact the environment. City life and farming that is non sustainable affect the climate in adverse ways. I recall when I was younger non sustainable farming created red dust storms in the city and resulted in farms that were dust bowls. Better farming practices ensured the land remained fertile and sustainable. We are able to restore the fertility of farm land and regulate the impact city life has on the climate and marine life by acting locally to effect global positive change. We just need to do it.
