LA doesn't need an NFL team

Los Angeles does not need an NFL team, for many reasons, such as traffic, pollution, energy cost, water needed for grass, and my not caring about sports), and that's there are so many sports teams in Greater Los Angeles who could get that attention instead, such as 4 rugby teams, 13 basketball teams, heck even 5 football teams, four in the women's American football leagues alone. And of course soccer (or association football), there are 11 pro teams, and another football club starting in Major league Soccer in 2017. There are so many of these already, why not give your attention to them instead of bringing back the NFL?
