How has the regulation of the negative effects of economic activity changed?

Requirements: I’m using this notes study for the exam, so just like how university students taking notes when the reading the books, the notes is not assignment to turn in, so don’t worried about sources and no need introduction and conclusion , the structure need to be clear and maybe using different color on words, the notes are mainly focus on answering the learning goals, so any information in the books that is relevant with learning goals are important, so the notes need to be more detail in explaining and sometimes the explanation in the books may difficult to understand, so the notes need to be explain clear, but the information in the books which not relevant with learning goals can’t be ignore, a brief and clear summaries on those not relevant to learning goals is good. For this notes, I need between 4 pages. If you have any future questions about making notes, I have an example notes, please lookup, it’s really good notes and that’s what I’m looking for, also I don’t want 100% copy & paste sentence in the notes from the readings. You need to answer these four questions： 1. How has the regulation of the negative effects of economic activity changed? How can the ‘old’ and ‘new’ type of regulating the externalities of economic activity be characterized? 2.Why has the regulation of the economy changed in recent decades from ‘government’ to ‘governance’? 3.how can current form of regulation be put into practice？ 4. What types of actors and instruments are involved in regulatory governance regimes such as the climate change governance regime?
