mineral exploitation contributes significantly to economic growth and development in most world economies. In africa, ghana is the second largest gold producer, contributing to about 5.7% of the countrys gdp. the mining sector in ghana consists of both small-scale and large-scale mining, each of which has varying environmental impacts. this paper provides an exposition on the environmental additional environmental problems with mining: In addition to the issues addressed above, there are many other environmental issues associated with mining: carbon output. mining, like most heavy industries, is dependent on fossil fuels, which generate the energy needed to operate a mine. To combat these carbon emissions, some countries have even if deep-sea mining is often quite costly since big machines have to be operated on the ground of the ocean, many companies think it will still be worth it to do so due to the scarcity of resources from conventional mining activities which may lead to a significant increase in world market prices for scarce metals and therefore to an
