A group of environmentalists have purchased shares in a mining company. Some 200 members of the group are now shareholders and holding various amounts of shares. The members of the group who have purchased shares are not against profits being made by their company, but are concerned that appropriate health and safety standards are not implemented by the company, and further that appropriate environmental safeguards are implemented when extracting a mineral, transporting it and manufacturing the final product. What rights do members have to question directors at a meeting regarding the companys environmental practices? What are the rights of members to actually call an extraordinary meeting in order to discuss a particular environmental issue that has arisen since the last meeting of members was held?
