Businesses have a moral obligation that must be politically enforced.
Explanation:
Businesses working from profits often use indiscriminate measures to garner profits for themselves while using their capital as economically as they can.
This includes the exploitation of workers. To counter this, we have trade unions.
Similar is the situation for conservation. Environmental issues indirectly affect the whole population of the country and every company has a part in it. Hence environmentally secure sanctions need to be put in place even if it eats into the company's profits.
