Q

riots or protests related to natural resource extraction

A

Peru’s 2012 Tintaya conflict involved protests against environmental pollution and the insufficient sharing of benefits from the local copper mine. Hundreds of locals from the Espinar province clashed with police and private security, resulting in dozens injured and several killed. Similar demonstrations of resentment and anger have occurred across Latin America, Africa and South Asia, where nearly three quarters of countries have experienced riots or protests related to natural resource extraction in the recent years. One database lists more than 2,300 active social conflicts worldwide that are related to natural resource extraction.

Q

human intervention (African national parks)

A

scientists analysed two national parks– Kenya’s Amboseli National Park, where the elephants were relatively undisturbed by human activity, and South Africa’s Pilanesburg National Park, where a large proportion of the elephant population was culled. It was later found that the Pilanesburg herd was unable to distinguish the calls of friends from foes due to a lack of adult guidance and knowledge. The culling of adult elephants had resulted in weakened decision making and behavioural responses.

Q

Samsung & renewable energy

A
  • Greenpeace protestors took to the streets during the Winter Olympic Games in South Korea in 2018, and activists hung banners and uploaded videos to spread awareness about Samsung’s non-environmentally friendly practices. Samsung has since managed to switch to renewable energy sources for 100% of the power used in the US, Europe and China.
  • however, it is possible that these targets have been achieved via the purchase of Renewable Energy Certificates (RECs), which could have negated the company’s emissions.
