There are many environmental problems associated with ruminant livestock and these problems continue to grow as the demand for meat-rich diets increases around the world. One of the biggest problems is that cows emit methane through eructation (or belching) as they chew their cud. Methane is a powerful greenhouse gas, some 25 times more potent at trapping heat than carbon dioxide. More than a quarter of all human-originated methane going into the atmosphere comes from raising livestock.
The federal government now appears to be headed down the path of not honoring America’s commitments to tackle global warming, but many of the country’s cities and states as well as its corporations have no intention of breaking our promises to the world.
Organizers of the Tokyo 2020 Olympic Games announced in February that all the Olympic medals for the games will be made from recycled materials. The strategic roadmap for the games, laid out in the document “Olympic Agenda 2020”, specifically calls for the inclusion of sustainability in every aspect of the games.
Americans toss out an almost unbelievable $161 billion worth of food every year. There are numerous efforts underway to address this problem, but they are mostly at the local level or in the business sector. To date, we have no national- or international-level policies that tackle the issue. In this regard, Europe is way ahead of us.
The new administration has promised to revitalize the coal industry in the U.S. A major part of this plan is to eliminate various regulations that hamper that industry. But the truth is that coal has lost ground for far more important reasons than regulation.
We recently talked about the increasing efforts by colleges and universities to embrace sustainability with the use of renewable energy sources. Those efforts are increasing in many places.
Globally, 40% of invertebrate pollinator species, such as bees and butterflies, are facing extinction. And since approximately three-quarters of the world’s food crops depend on pollination, the decline of these pollinators could pose a threat to food security around the globe.
According to a recent study published in the journal Global Change Biology, rising CO2 levels in the ocean can disrupt the sensory systems of fish and can even make them swim toward predators and ignore the sounds that normally deter them from risky habitats.
It’s no secret that there is a lot of plastic debris in our oceans. In fact, scientists estimate that there is more than 165 million tons of plastic trash swirling about in our oceans today, with an additional 8.8 million tons flowing in every year. And as the oceans swell with plastic litter, hundreds of marine species are ingesting the stuff – often with dire consequences.
The Red and White Fleet has been ferrying tourists around San Francisco Bay since 1892 and is a company committed to environmental sustainability. When looking for ways to reduce the emissions from its fleet of passenger ferries, the company wondered if there was a way to eliminate emissions entirely. That question was put to researchers at Sandia National Laboratories in a very specific form: Is it feasible to build and operate a high-speed passenger ferry solely powered by hydrogen fuel cells? According to a recently-released report, the answer is yes.
Halloween is traditionally a day when we choose to ignore the inconvenient truths about candy. Many of us overindulge on sweet treats and give little thought to what’s inside… particularly with respect to nutrition.
As the world’s population grows and becomes more urban and affluent, the amount of solid waste we produce grows and grows. Over the past century, the total amount has risen tenfold. By 2025, the world-wide total is expected to double again. The average person in the United States throws away their body weight in garbage every month.
Most recent news about coral reefs around the world has been bad news. There has been unprecedented coral bleaching in places like Australia’s Great Barrier Reef. The effects of climate change – including warming temperatures and rising seas – as well as the recent El Niño event have led to damaged reefs across the globe.
Few of us cook with palm oil or have ever even seen the stuff. Nevertheless, half of the world’s consumer products include it as an ingredient and the global market for palm oil could be as high as $50 billion. The palm oil industry has been tied to environmental destruction in countries such as Malaysia and Indonesia and has been found to be complicit in human rights violations.
