In my one memorable exchange with him, I pointed out that his argument on the question atissue was circular.
在我与他的一次令人难忘的交流中,我指出,他在这个问题上的论点是循环的。

It looks like what's atissue is less how long your food stays on the floor and much more how contaminated with bacteria that patch of floor happens to be.
看起来问题的焦点不太在于你的食物在地上停留的时间长短,而更在于那块地被细菌污染到了什么程度。

Several current studies are looking at these effects and I really do hope we can find a way to deal with this issue before these ecosystems are adversely affected.
