Doing Your Bit: Ten Simple Ways to Help Reduce Air Pollution
By The Editors Every day, we can choose to do things that help to reduce air pollution. And if we are aware of what we do, we can do even more. Below are a few ideas to make a difference – Ten simple ways to help reduce air pollution. 1. Conserve energy – turn off appliances, computers and lights when you leave the room. Connect your outdoor lights to a timer or use solar lighting. 2. Dress for the weather and adjust layers before adjusting the thermostat. 3. Seal containers of household cleaners, workshop chemicals and solvents, as well as garden chemicals to prevent volatile organic compounds…

Do Sea Turtles Eat Plastic Marine Debris? Yes!
By The Editors Floating marine debris accumulates in five main oceanic gyres. These debris accumulations consist mostly of plastics and are called great garbage patches. In recognition of the global threat posed by the great garbage patches, the United Nations Educational, Scientific and Cultural Organization (UNESCO) has recently granted them a symbolic State status, and officially recognized the Garbage Patch State. Marine debris gathers in drift lines and convergence zones, which are also important feeding areas for many oceanic species, including sea turtles. Now, results from an analysis of global research data from the past 25 years show that green and leatherback turtles are eating more plastic than ever before. The analysis…

What is Carbon Farming?
By Roberta Attanasio Greenhouse gases (carbon dioxide, methane, nitrous oxide, fluorinated gases, and ozone) work like the glass walls of a greenhouse and are responsible for the greenhouse effect. What is the greenhouse effect? It’s a process in which greenhouse gases let the radiation from the sun onto the Earth’s surface. At the same time, they trap the heat that reflects back up into the atmosphere. The greenhouse effect keeps our planet at an average 59 degrees Fahrenheit (15 degrees Celsius). However, if the greenhouse effect is too strong, our planet gets warmer and warmer. This is what is happening now — the greenhouse effect is becoming stronger because of increased release of greenhouse gases in the atmosphere.…

The $11 Trillion Reward
By The Editors According to a brand new report released today by the Union of Concerned Scientists (UCS), increasing our consumption of fruits and vegetables could save more than 100,000 lives and $17 billion in health care costs from heart disease each year. In addition, better farm policies, designed to encourage production of healthy food instead of processed junk foods, will help us reap those benefits. “The $11 Trillion Reward: How Simple Dietary Changes Can Save Lives and Money, and How We Get There” examines the linkage between fruit and vegetable intake and incidence of cardiovascular diseases. These diseases, the leading killer of Americans, include coronary heart disease and stroke, which together are…

Benzene, Leukemia and Lymphoma
By Roberta Attanasio It’s said to have a sweet smell, or a gasoline-like odor. It’s mostly in the air, and sometime in the water and soil. It’s found all around the world. It’s in cigarette smoke and gasoline vapors. It’s a known human carcinogen – a substance known to cause cancer. It’s benzene. Its target organ is the bone marrow, the soft spongy tissue that lies within the hollow interior of long bones and produces all types of blood cells. The Agency for Toxic Substances and Disease Registry (U.S. Department of Health and Human Services) in the “Toxicological Profile for Benzene” states: “Everyone is exposed to a small amount of…

Arsenic in Rice: Links to Genetic Damage
By The Editors Rice is a staple food for over 3 billion people worldwide. Unfortunately, rice contaminated with arsenic can be found in several regions of our planet. Although serious concerns have been raised in the past few years over the consumption of rice tainted with high levels of arsenic, there was no direct proof of its harmful effects on human populations. Now, results from a new study indicate that staple consumption of cooked rice containing high levels of arsenic leads to genotoxic damage. Arsenic, one of the heavy metals, is a chemical element normally present in water, air and soil. It is released from volcanoes and from the erosion…

The Information Age
By The Editors The Information Age is the era shaped by information and communication technologies—and therefore by information-based industries. It started in the mid-1970s in association with the Digital Revolution, and partially overlaps with the Space Age, which started in the late 1950s with the launch of the world’s first artificial satellite. The Information age has been characterized by widespread optimism about the ability of technology to solve most of the world’s challenges—for example food security, environmental degradation, economic growth and social inclusion. However, we now know that technology, by itself, cannot provide solutions to these challenges. One of the recognized fathers of the Information Age is the scientist Norbert Wiener,…
