TAILIEUCHUNG - MINING AND WATER POLLUTION

The plastic breaks down into such small bits that researchers can't strain it out of the water, so it’s almost impossible to clean up. Birds and fish mistake it for food and the plastic ends up in their stomachs. And that could end up in our stomachs, according to biomedical researcher Bruce Blumberg of the University of California at Irvine Some chemicals in the plastic, he says, can make their way into the tissue of the fish we eat. The possible endocrine disruptors in plastic, he says, could be hazardous. BLUMBERG: “Is ingesting plastic. | MINING AND WATER POLLUTION Water is essential to life on our planet. A prerequisite of sustainable development must be to ensure uncontaminated streams rivers lakes and oceans. There is growing public concern about the condition of fresh water in Canada. Mining affects fresh water through heavy use of water in processing ore and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly human activities such as mining threaten the water sources on which we all depend. Water has been called mining s most common casualty James Lyon interview Mineral Policy Center Washington DC . There is growing awareness of the environmental legacy of mining activities that have been undertaken with little concern for the environment. The price we have paid for our everyday use of minerals has sometimes been very high. Mining by its nature consumes diverts and can seriously pollute water resources. Negative Impacts While there have been improvements to mining practices in recent years significant environmental risks remain. Negative impacts can vary from the sedimentation caused by poorly built roads during exploration through to the sediment and disturbance of water during mine construction. Water pollution from mine waste rock and tailings may need to be managed for decades if not centuries after closure. These impacts depend on a variety of factors such as the sensitivity of local terrain the composition of minerals being mined the type of technology employed the skill knowledge and environmental commitment of the company and finally our ability to monitor and enforce compliance with environmental regulations. One of the problems is that mining has become more mechanized and therefore able to handle more rock and ore material than ever before. Therefore mine waste has multiplied enormously. As mine technologies are developed to make it more profitable to mine low grade ore even more waste will be generated in the .
