Answer 2

Answer:

The way we use resources provokes often irreversible ecological change. Extraction and processing of non-regenerative raw materials are often energy intensive activities involving large scale interventions in ecosystems and the water balance and result in air, soil and water pollution. Even the extraction and production of renewable resources often involve extensive use of energy, materials, chemicals and in some cases water; and all this translates into pollution. Greenfield land is often transformed to create arable land and in some cases whole ecosystems are destroyed in the process.

In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation

Raw material production

People in the regions in question report abuses such as severe human rights violations or permanent ecological damage in the wake of raw material extraction, which often provokes health problems resulting from air pollution and drinking water contamination. Other consequences include local populations being driven off their land and forced to settle elsewhere – not to mention growing poverty. In areas that suffer these consequences, efforts on the part of companies that engage in mining and similar operations to institute sustainable development are few and far between. Moreover, in some states profits from raw material production are used to finance armed conflicts. According to UN statistics, natural resources play a key role in 40 percent of all intra-state conflicts.
