There are several governmental and nongovernmental organizations, including UNICEF and Water Aid, working to help poor communities in Asia and Africa obtain sustainable supplies of drinking water and sanitation facilities. Water shortages happen in the United States, too -- many states have programs to...
The water shortages are mainly due to natural causes: changing weather patterns and melting snow and ice caused by global warming are having a severe impact on the world's water systems. This means that around 1 billion people in the world do not have access to safe ...
For example, the batteries in electric vehicles rely on lithium, an element that is often strip-mined from South American rain forests.15Hydroelectric dams have low carbon emissions, but high impacts on the salmon and other species that rely on those waterways.16Green energy devices ...
Lithium-ion: Most plug-in hybrid and all-electric vehicles use lithium-ion batteries composed of multiple lithium-ion cells. This option tends to offer better efficiency, requires less maintenance, and provides a longer lifespan than lead-acid batteries. However, they are usually more expensive th...
Using it this way is the best and most obvious way to extend the longevity and charge capacity of your laptop, especially if your device has a lithium-ion battery. For instance, the batteries of Apple MacBooks take a big hit when fully charged, because it makes them susceptible to ...
Anyone exhibiting this kind of behavior should be gently coaxed into drinking some water and eating a little junk food. 5. Leave no one behind. Everyone should have an idea of how they’re getting home before they start drinking. Sucky people leave their friends to fend for themselves ...
Case in point: More than half of Native Americans do not have access to regulated drinking water. “Choosing to filter your water is a privilege that not everyone can afford, which exacerbates health disparities,” Evans say. “This inequity means that wealthier communities are better able to...
Cooperating with health service organisations in conducting temperature audits of vehicles by carrying in-vehicle temperature recording devices. However, this could present a challenge if the recording devices were powered by lithium batteries, which are subject to the DGR (Table 1). In addition, othe...
