HOW TO DONATE FOOD

July 27, 2016 @ 9:38 AM

By redirecting unspoiled food from landfill to our neighbors in need, individuals can support their local communities and reduce environmental impact. Non-perishable and unspoiled perishable food can be donated. Donated food can also include leftovers from events and surplus food inventory.

Where to Donate

 - Food Pantries: Food pantries, food banks and food rescue programs are available across the world to collect food and redistribute it to those in need.

 - Food Banks: Food banks are community-based, professional organizations that collect food from a variety of sources and save the food in warehouses. The food bank then distributes the food to hungry families and individuals through a variety of emergency......

10 WAYS TO HELP WILDLIFE

July 25, 2016 @ 9:34 AM

Habitat loss and the extinction of species are devastating consequences of irresponsible human actions. The problem’s complexity and reach often leads people to feel unable to make a difference. However, every single action we take is crucial in bringing about change. Although individually our contribution may seem small, the sum of our efforts can really make a huge difference.

Protect Wildlife Habitat

The most pressing issue that threatens species is their progressive loss of habitat. Animal agriculture, deforestation, and development impact the environment in profound ways: erosion, soil compaction, desertification and changes in climate. When the land is manipulated in such a manner, wildlife habitat alteration or ......

WHAT HAPPENS WHEN YOU AVOID ALL PLASTIC?

July 19, 2016 @ 11:38 PM

Photo: The well-known documentary "Plastic Planet" by Werner Boote starkly illustrates the dangers of plastic and synthetics for human beings, and also shows how ubiquitous plastic is. Motivated by this multiple award-winning film, a family of five from Styria completely avoided plastics in their home environment for several months. Environmental medicine experts from MedUni Vienna monitored them and analyzed their urine samples at the start of the experiment and again two months in. The main finding of this human biomonitoring study: even if one avoids plastics as far as possible in the home, a certain amount of exposure is inevitable from chemicals and from the environment.

In the middle of November, family K started to eliminate .........

AIR POLLUTION LINKED TO KIDNEY DISEASE

July 19, 2016 @ 10:28 AM

Photo: Multiple Coal Fossil Fuel Power Plant Smokestacks Emit Carbon Dioxide PollutionWhile air pollution is known to cause respiratory and cardiovascular diseases, a new study indicates that it also causes damage to the kidneys. The findings call for attention on the role of air pollution in the development of kidney disease in urban areas.

Air pollution has become a serious problem in many cities in China, but the extent of its impact on individuals' health is unclear. To examine how particulate matter in the air is affecting kidney health, a team led by Fan Fan Hou, MD, PhD and Xin Xu, MD, PhD (Southern Medical University, in Guangzhou, China) analyzed data on kidney biopsies taken over 11 years from 71,151 patients from 938 hospitals in 282 cities across China, encompassing all age groups.

On average, the .........

TROPICAL FORESTS OVEREXPLOITED BY LOGGING

July 18, 2016 @ 9:55 AM

Photo: Widely hailed as a renewable natural resource, tropical timber from old-growth tropical forests is selectively logged worldwide at an unprecedented scale. But research now reveals that these sources of timber are far from sustainable and environmentally friendly.

A new study reveals that once prime tropical hardwoods – such as Brazilian cedars, ipe (Brazilian walnut), and rosewood – have been logged, they do not grow back to commercial levels and are at risk from disappearing altogether.

Lead author Dr Vanessa Richardson, from  the University of East Anglia’s School of Environmental Sciences, said: “Slow growing and commercially valuable species of all kinds have been overexploited over the course of human .........

HOW TO CHOOSE LIGHT BULBS

July 14, 2016 @ 11:09 AM

If you need a new light bulb, you have a hard decision to make. There are several kinds of light bulbs to choose from. What are they? Does it make a difference?

Lights use a lot of electricity, so it's important to use the most efficient ones. Efficient bulbs use less electricity to make light. Using less electricity in turn creates less pollution and saves you money. It's better for everyone.

So what are the different kinds of light bulbs? The most common light bulbs you can find at the store are incandescent, compact fluorescent (CFL), light emitting diodes (LED), fluorescent, and halogen. It can feel overwhelming. Let's look at each one individually.

Incandescent

If you think about a regular light bulb,......

ARCHITECTS SHOULD LET THE MICROBES IN

July 13, 2016 @ 8:28 AM

Architectural design is often concerned with energy efficiency or aesthetics, not microbial exposure. But, Yale environmental engineers make a case for assessing the benefits of having these unseen organisms in our homes. Maybe, they say, instead of pushing all of them out, we should let the right ones in.

"It's a common misconception that all microbes found in one's home are hazardous to your health," says Yale Professor of Chemical and Environmental Engineering Jordan Peccia, co-author of the review with PhD student Sarah Kwan. "Many have no impact on health, while some may even be beneficial."

Past studies have shown that children growing up on a farm (or even in a home close to a rural area), are exposed to.........

ENERGY FROM SUNLIGHT

July 11, 2016 @ 9:26 AM

Chemists from the Universities of Basel and Zurich in Switzerland have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules.

Green plants are able to temporarily store electric charges after the absorption of sunlight by using a so-called molecular charge accumulator. The two research teams were able to observe this process in artificial molecules that they created specifically for this experiment.

The chemists excited the artificial molecules using a laser, which then made it possible to store two negative charges for a short time span for the very first time. They succeeded in storing the charges long enough,.........

CIGARETTE BUTTS METALS THREATENING MARINE ENVIRONMENTS

July 10, 2016 @ 11:20 AM

Trillions of cigarette butts are littered annually and their metal contaminants are endangering marine environments. Littered cigarette butt metals are leaching into aquatic ecosystems and potentially entering the food chain.

Cigarette butts are the most common form of litter found in the marine environment, with an estimated 5 trillion or so discarded outdoors around the globe every year. Research has shown that metals can leach from cigarette butts. To gain an understanding of the potential implications, levels of metals in cigarette butts were recently monitored at nine different locations along the north part of the Persian Gulf in the Bushehr seaport coastal areas.

The metals assessed included cadmium (Cd), iron (Fe), arsenic (As) .........

SOLAR ENERGY CAN BE TRANSFORMED INTO FUEL

July 9, 2016 @ 8:45 AM

The sun is a clean and inexhaustible source of energy, with the potential to provide a sustainable answer to all future energy supply demands. There’s just one outstanding problem: the sun doesn’t always shine and its energy is hard to store. For the first time, researchers have unveiled a chemical process that uses the sun’s thermal energy to convert carbon dioxide and water directly into high-energy fuels: a procedure developed on the basis of a new material combination of cerium oxide and rhodium. This discovery marks a significant step towards the chemical storage of solar energy.

The sun’s energy is already being harnessed in various ways: whilst photovoltaic cells convert sun light into electricity, solar .........
