People's World posted a article in Nature & WildlifeThe latest ecological disaster has left Colorado's Animas River a sickly orange and yellow, after an accident on Aug. 5 sent at least three million gallons of mine waste gushing into the water. The spewage came from the abandoned Gold King Mine, and occurred when an EPA mining safety team used equipment to - ironically enough - reduce pollution emanating from the disused site. Now the sludge is spreading, and it reached New Mexico on Aug. 10, flowing from the Animas into the San Juan River there, as officials struggled to gain control of the situation. The wastewater contains toxic heavy metals including lead, which can harm fetal development and cause vision impairment and kidney disease, and arsenic, which at high levels could cause paralysis, blindness, and cancer. The contamination was apparently the very thing EPA workers were attempting to treat before inadvertently unleashing it upon the environment. "The project was intended to pump and treat the water and reduce metals pollution flowing out of the [Gold King] Mine," EPA spokesman Rich Mylott confirmed. There has been no drinking water contamination, because utilities shut down their intake valves in time to prevent the plume from reaching their systems. Farmers also closed the gates on their irrigation ditches to preserve their crops. But the same could not be said for the wildlife that will surely be adversely affected, including local fish; the EPA has warned boaters and anglers to stay far away from the water for this reason. Meanwhile, New Mexico health officials were outraged that the EPA did not tell them about the plume until a day after it reached the cities of Aztec and Bloomfield, causing a last-minute scramble to cut off the river's access to water treatment plants in those areas. As it is, the EPA has released very little information, and virtually nothing in the way of updates, concerning New Mexico's share of the problem. "We're having a real problem getting the EPA to tell us what's in this stuff," said Don Cooper, emergency manager for San Juan County. "We're just kind of shooting in the dark and telling people to stay away from it." Though EPA officials are reportedly continuing to conduct tests to determine the health and environmental impacts of their mistake, nothing has yet been said about a cleanup. In fact, it would seem that experts are hoping for the situation to resolve itself; the agency's coordinator Craig Myers said, "It's hard to know what's going to happen [to the Animas River] as more river flows join it. It is diluting. The sludge of contaminants is going to be settling out in places." But for affected residents and concerned environmentalists, pollution, sadly, is more readily available than answers. What is apparent is that the EPA's initial estimate of the amount of spillage - one million gallons - has proven to be wrong, as the U.S. Geological Survey has clarified that the incident sent at least two million gallons more into the Animas. Kim Stevens, director of advocacy group Environment Colorado, remarked, "This is a really devastating spill. We've been hearing from rafting companies and other businesses that rely on the river that if they can't get their clients out on the river in the next couple of days, they may have to shut down their doors." And then, of course, there's the impact to the livelihoods of fishermen to consider. She added, "The fish population is especially very sensitive to water contamination, and we really won't be able to see what the impacts are until all of the pollution has run its course. Time will tell." The poisoned water also runs through sensitive indigenous peoples' territory, and the Navajo Nation people have said they will not stand for the toxification of their land. Nation president Russell Begaye stated, "They're not going to get away with this. The EPA was right in the middle of the disaster and we intend to make sure the Navajo Nation recovers every dollar it spends cleaning up this mess and every dollar it loses as a result of injuries to our precious natural resources." And things are only going to get worse, at least in the short term, because the next stop on the mine waste's tainted tour is Utah. The orange and yellow wastewater is still wending its way through the San Juan River, which eventually joins Lake Powell over in the Beehive State. Officials in the adjacent town of Montezuma are making preparations by shutting off water pumps there, and the same is being done in the neighboring town of Aneth. Trouble, of a most toxic variety, is most certainly brewing. "There are people who want to know, 'Okay, what's going to happen now? Are you going to fix this?' " said Michele Truby-Tillen, a spokesperson for New Mexico's San Juan County Office of Emergency Management. And above all, she said, as health concerns worsen, one question nags at the backs of people's minds: "How are we going to protect our families?"
Green Blog posted a article in ScienceIn just 15 years the world could suffer a catastrophic global water crisis, the United Nations (UN) warn in its annual World Water Development Report. The UN report forecasts that global water demand will increase by 55 percent by 2050. If current trends of water usage continues the world could suffer a 40 percent shortfall in water supply as early as by 2030 – which could potentially have catastrophic consequences. Groundwater supplies are quickly diminishing and the report estimates that 20 percent of the world’s aquifers are currently over-exploited. There is an urgent need to manage water more sustainably, the UN report concludes. If we fail to do this, the competition for water will increase and lead to “significant impacts” on both the economy and human well-being. It will also increase the risk of conflicts, the UN report warns. Safe drinking water supplies will continue to dwindle as long as water pollution continues to be ignored and go unpunished by local authorities, and water use remains wasteful and unregulated, as it unfortunately does in many nations, the UN says in its report. In order to mitigate this water crisis, the UN is urging politicians, communities and industries to rethink its water policies and to make a greater effort to conserve water. The 55 percent increase in water demand is mainly due to growing demands from manufacturing, thermal electricity generation and domestic use. But due to increasing population numbers and consumption levels, agriculture will also need to substantially increase its food productions to keep up with demand – and this will in turn increase water usage. “By 2050, agriculture will need to produce 60 percent more food globally, and 100 percent more in developing countries […] global water demand for the manufacturing industry is expected to increase by 400 percent from 2000 to 2050, leading all other sectors, with the bulk of this increase occurring in emerging economies and developing countries,” the UN report said. “Unless the balance between demand and finite supplies is restored, the world will face an increasingly severe global water deficit.” Considering that current demands for water in the agriculture sector is already unsustainable, this will be a difficult task. The agriculture sector must increase its water use efficiency by reducing water losses in the production process, and to “increase crop productivity with respect to water” availability and demand, the report says. The UN report also points to two worrying global trends that are converging: climate change and growing economic development in poor developing countries. This convergence will especially “intensify the water insecurity of poor and marginalized people in low income countries.” “Water resources are a key element in policies to combat poverty, but are sometimes themselves threatened by development,” said UNESCO Director-General, Irina Bokova. “Water directly influences our future, so we need to change the way we assess, manage and use this resource in the face of ever-rising demand and the over exploitation of our groundwater reserves.”
Water is the most precious natural resource. It is also one of those natural resources that cannot be created more. The amount of water in this world is fixed. We just need to use it with care to continue meeting our water needs. We need to raise public awareness on water to let people conserve water as much as they can. For this purpose we need to have punch lines about various issues related to water. These 100 slogans on water can be the best messages for water awareness if they are communicated to right audience at right time.
