In the 1940s and 1950s, synthetic polymers became very popular. These man-made materials were designed to be cheap and durable and soon began replacing metals and glass in everything from automobiles and airplanes to bottles and dishes.
Most of us are likely familiar with the saying ‘you are what you eat.’ But what we eat – those food choices – can have a profound impact on the planet.
Cities are particularly miserable during heatwaves. With lots of concrete and asphalt surfaces, they soak up lots of heat and re-radiate it. Lots of tall buildings block cooling breezes. Factor in car exhaust and heat from air conditioners and it all adds up to the urban heat island effect. Cities can be several degrees warmer during the day and as much as 20 degrees warmer at night. All of this extra heat is not just a comfort issue, it is a serious health problem.
Our national parks are supposed to be places that allow us to commune with nature. They offer incredible vistas and amazing sights. As a result, millions of Americans and visitors from around the world are drawn to these places – too many millions, in fact.
Air pollution is deadly. Studies have found that fine particulate matter, such as airborne pieces of dust, dirt, smoke, soot, and other microscopic particles can enter our lungs and bloodstream, contributing to major health conditions such as heart disease, stroke, cancer, and kidney disease.
There are frequent stories in the news about the terrible air pollution problems in major Chinese and Indian cities. With pollutant levels far in excess of any recommended safety thresholds, the air in these places represents a health crisis.
U.S. automakers have always been reluctant partners in the nation’s efforts to reduce air pollution and improve fuel efficiency. There have been struggles for decades between the carmakers and the government in setting Corporate Average Fuel Economy (or CAFÉ) standards. During the Obama administration, some of the most demanding fuel economy and emissions standards were mandated.
Every year, the Environmental Working Group ranks pesticide contamination in 47 popular fruits and vegetables for its Shopper’s Guide to Pesticides in Produce. The environmental nonprofit has created this ranking annually since 2004.
Blacktip sharks are snowbirds, to use a cross-species metaphor. At least, they usually are. The males of the species swim south to southern Florida during the coldest months of the year and head back north to North Carolina in the spring to mate with females.
For years, China has been struggling with some of the worst air pollution in the world. According to the European Union, only 1% of the country’s half a billion city dwellers were considered safe because almost all of its major cities were covered with what was described as a toxic grey cloud.
Biomimicry is learning from and then emulating nature’s forms, processes, and ecosystems to create more sustainable designs. Mother Nature is already the inspiration for countless products and designs ranging from Velcro copied from plant burs to the shape of wind turbines modeled after whale fins. There are wetsuits inspired by beaver pelts and office buildings that copy termite dens. Increasingly, innovators are looking at nature for designs in architecture, chemistry, agriculture, energy, health, transportation, computing, and even for the structure of organizations and cities.
Since the 1980s, China has been the largest importer of foreign trash. In 2012, up to 56% of global exported plastic waste wound up in China. The trash has been both a valuable resource for the country’s booming manufacturing sector as well as an enormous source of environmental and health problems.
2018 is just around the corner. Popular resolutions for the New Year always seem to include things like improving health, traveling more, spending less money, and so on. But one resolution that isn’t as popular but could collectively have a major impact is committing to living a cleaner and greener life.
A group of 10 major transnational corporations has launched a new global initiative to slash vehicle emissions by increasing the number of electric vehicles in their corporate fleets. Known as EV100, the initiative commits companies to integrate EVs in their owned or leased fleets and install charging stations for customers and employees.
Globally, an estimated 4.5 billion people are exposed to particulate air pollution levels that are at least twice that of what the World Health Organization considers safe. But the impact that sustained exposure to air pollution has on a person’s life expectancy has remained a frustratingly unanswered question. That is until now.
For many people, commuting to and from work is a time-consuming, stressful part of their lives. In fact, the average American spends nearly an hour a day facing traffic jams and congested highways. There are direct health hazards in commuting as well. Drivers are exposed to increased amounts of air pollutants that have been linked to a wide range of medical problems including cardiovascular disease, respiratory issues and even lung cancer.
It is always good to learn about more reasons to eat chocolate and Italian researchers have provided us with some impressive facts to digest with our delicious treats.
Now that the Trump administration announced that the United States would cease implementation of the Paris Climate Agreement, various state, local and corporate entities in this country have been stepping up to assume climate leadership.
A group of more than 200 scientists and medical professionals has issued a consensus statement in the journal Environmental Health Perspectives urging that antimicrobial chemicals like triclosan and triclocarban should not be used in consumer products. The experts say that these substances offer no health benefits and are actually causing health and environmental harm.
