英語→日本語にはできるんですが言ってる意味が分かりません。。

下記文章の大意を教えていただけませんでしょうか。
（なんとか英語→日本語には出来たのですが、言ってる意味がイマイチ理解できません。）


Some readers may be disappointed or outraged that I place the ultimate responsibility for business practices harming the public on the public itself. I also believe that the public must accept the necessity for higher prices for products to cover the added costs, if any, of sound environmental practices.

My views may seem to ignore the belief that businesses should act in accordance with moral principles even if this leads to a reduction in their profits. But I think we have to recognize that, throughout human history, in all politically complex human societies, government regulation has arisen precisely because it was found that not only did moral principles need to be made explicit, they also needed to be enforced.

前半部分と後半部分の繋がりがよくわかりません。どなたか解説いただけませんでしょうか。

※この文章はIELTS に出てくる「environmental practices of big businesses」という文章の一節です。
