5. Conclusions The result of the 29 country study yields a global average of 18.4 tonnes of CO2 equivalent emissions and 1.87 Pts per kg of primary aluminium production. In total, the aluminium industry was responsible for the emission of about 861Mtonnes of CO2eq. in 2012, both directly and indirectly.
First, agricultural production is constrained in nearly every country due to changing climatic conditions and poor soil quality (Titilola & Jeje 2005, pp. 116-144). Global temperatures have risen by nearly 1.530F in the last 100 years (Chauhan 2008, p. 67). In addition, the level of rainfall has been declining steadily.
During rainfall, water seeps between the stones to penetrate the ground, keeping the environment in balance and potentially supporting the life that lives there. Accordingly, gravel is an environmentally sound choice for redoing your driveway (or creating one from scratch).
The typical impact of having a mineral extraction processing plant in the local area is considerable in terms of its effect on the landscape, its noise and visual pollution and its permanent destruction of the local habitat. Impact on the local landscape The open fields between Benson and Dorchester are of great historical interest.

[1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal wildlife, it also leads to a huge loss of biodiversity as plants and aquatic habitats are destroyed.

Impacts include bed degradation, bed coarsening, lowered water tables near the streambed, and channel instability. These physical impacts cause degradation of riparian and aquatic biota and may lead to the undermining of bridges and other structures. Continued extraction may also cause the entire streambed to degrade to the depth of excavation.
