Have there been significant improvements in factory farming?
Definitely, most notably, in the European Union where they've begun by banning some of the worst forms of abuse on farms. Before you can change something like that you need to create awareness of what is being done to animals and what's wrong with what's being done to animals.
But how is it possible to consider factory farming issues improved when ag-gag legislation is passing?
It's not that factory farming isn't still there and an issue, it was pretty bad then and in some ways it's grown bigger and more dominant. But there are more alternatives and it's easier to get those alternatives.
What are the alternative options?
We haven't gotten rid of the problem and we need to go a lot further in understanding the problem. For animal and environmental reasons, change is happening but we're not over the hump yet. I think it's quite easy to easy to envision the abolition of factory farming. We don't need these animal products, they're not an efficient way of producing food. We're developing more and more alternatives all the time. Vegetarians and vegans are rising steadily. I guess a lot of people would just go to the grocery store and buy what they buy because they don't think ethically at all, it's just easier.
