If the host country's environmental regulation is lower than the country, there is an ethical problem. Developed countries formulate many regulations concerning pollution, and developing countries often lack regulations. Lack of regulation often leads to a higher level of pollution in developing countries. Nigeria is the most populous country in Africa and countries in which people are facing environmental problems in order to allow foreign multinational companies to operate their business while infringing on human rights.
An example of an ethical problem previously dealt with by Shell is the difficulty they encountered in Nigeria. The two main ethical considerations they face are current discussions on environmental issues and Islamic laws caused by the oil production in Niger Delta. Responding to Shell's environmental problems is to continue investing in the infrastructure to replace the pipeline if necessary, to bury all pipelines, upgrade the Rover Terminal and Production Terminal. Shell invested 52 million dollars in Niger Delta in 1999 and said it is offering a wide range of infrastructure projects such as hospitals, health centers, schools, water supply systems and electricity.
According to the Ministry of Petroleum Resources, there are 159 oil fields and 1,481 oil fields in Nigeria. The domestically most productive area is the Niger Delta Basin on the coast of the Niger Delta, or the "South - South" region containing 78 out of 159 oil fields. Most oil fields in Nigeria are scattered small, but as of 1990 these small non-production oil fields accounted for 62.1% of total production in Nigeria. This contrasts with the 16 largest oil fields that produced 37.9% of Nigerian oil at that time.
The estuary of the Niger River is a busy shipping base that provides access to transport carriers that transport cargoes entering and leaving Nigeria. In exporting, Nigerian oil caused severe pollution in the Niger Delta, causing serious pollution of up to 13 million barrels, due to accidents, spills, damage, general oil production, such as Bohkharam. Petroleum 1 since 1958 is economically, environmentally and mentally important for India, the Ganges River has always been considered one of the most contaminated rivers in the world. Despite being used for bathing, ritual use, and sewerage, the Ganges river supplies fresh water to about 500 million people. Combinations of fertilizer contamination and industrial waste in industrialized cities such as Kanpur, Allahabad, Varanasi, Patna, etc. are harmful to human health for the waters of the Ganges River and face severe environmental risks .
