SRI Funds and Business Ethical Obligations

This week's content discussed SRI funds, corporate social responsibility, and environmentalism. Consider and comment on the following:

Consider the principle of profit maximization and the notion that businesses shouldn't be obligated to do anything but make money. Do you think businesses have an obligation to help support society and the natural environment?

Considering how poor businesses are at self-regulation (evidence of this is everywhere), should the government step in and require businesses by law to behave in certain ways (e.g. environmental and societal welfare laws)?

Why or why not?
