ELI5: Why is beef/red meat bad for the environment?

Over the past year, I've seen numerous headlines saying that beef/red meat is bad for the environment and everyone should eat more fish and poultry or even go vegan. 

Why is red meat/cattle so much worse than other forms of meat?

Basically to produce a pound of beef you need a lot more water and fodder than you do for a pound of chicken. Of course if you eat plants and water directly you of course need even less than if you use them to feed a third party animal.
