Solar energy is more environmentally friendly. This alternative source does not rely on the incineration of carbonaceous substances to produce energy unlike commonly used fossil fuels and therefore does not worsen the air and water pollution problems that the world is currently facing. . Solar energy also has only a few adverse effects on society and these can be easily eradicated with modern technology and strict regulation. During the energy production process, solar plants release toxic chemicals; However, these chemicals do not pose a threat because solutions already exist to remedy this situation. Apart from this, solar energy is classified under renewable energy; therefore, it does not cause the damage usually experienced when using fossil fuels. Fossil energy production involves hazardous activities, such as mining, drilling, land clearing and waste disposal, which could be destructive to both humans and the environment. Mining causes soil erosion, which could exterminate soil organisms and destroy aquatic ecosystems. The land reclamation method is not a solution because the chemical properties of the reclaimed mine soils have been enormously altered and therefore this method cannot guarantee the regrowth of native flora. The Bagacay Mine in Hinabangan, Western Samar, Philippines is an example of destruction caused by mining. Reports show that the area is devoid of vegetation, narrower streams and unstable slopes which could cause landslides as well as siltation of drainage systems (Bureau of Mines and Geosciences and Environment and Conservation Division mining safety, nd). On top of that, mining is dangerous for workers. A survey by Goodstein (2005) found that the number of casualties from coal mining in England alone exceeded 100,000 during the second half of the 19th century. Oil drilling also has negative impacts; it contributes to pollution through oil spills, gas flares and waste discharges. The Niger Delta, located in Africa, is one of the largest wetlands in the world and has been devastated by oil exploitation and exploration. Between 1993 and mid-2007, 35 cases of oil spills were recorded. These are disastrous because oil spills release hydrocarbons into the ground and water sources and contaminate crops as well as marine ecosystems. Oil spills also prevent the absorption of oxygen in mangroves and ultimately lead to death. Gas flares also release hydrocarbon compounds such as methane and sulfur oxides, which contribute to greenhouse gases..
