The livestock sector has been reported to be responsible for 18% of the total anthropogenic greenhouse gas (GHG) emissions on a worldwide basis (FAO, 2006). The GHG's considered in this publication are carbon dioxide, methane and nitrous oxide. It isimportant to remember that this is a ...
According to scientists, the methane cows belch out while turning feed into food is a far more powerful greenhouse gas than even the carbon dioxide produced by burning fossil fuels. Researchers at an experimental farm run by Scotland's Rural College believe that they have found a way to satisfy...
Carbon dioxide is a naturally occurring greenhouse gas. Others include water vapor, methane and nitrous oxide. These gases help keep the Earth warm by absorbing the sun's energy and by redirecting energy back to the Earth's surface. An increase in the amount of carbon dioxide creates an overa...
A byproduct of this interaction is methane gas, which gets vented into space. Meanwhile, reclaimed oxygen enters the ISS air supply [source: Starr]. While that's going on, drinking water gets recycled as some of these very mechanisms repackage exhaled air. Water is also reclaimed by ...
As accelerators of global warming, many air pollutants such as methane, black carbon and sulphate aerosols are contributing to what experts are calling “a silent public health emergency”, resulting in an increasing number of recorded respiratory illnesses and early deaths. What's more, aeroallergen...
As the cows digest the foods they eat, like grass, they produce methane, released when they burp and fart. Methane is the most potent gas contributing to global warming. Burp-Trapping Masks A UK-based startup hascreated a burp-catching muzzlethat fits over a cow’s nose and mouth ...
Ultimately, what really matters isn’t the amount of greenhouse gas emissions; what matters is the higher temperatures and their impact on humans. And on that front, a gas like methane is much worse than carbon dioxide. It drives the temperature up immediately, and by quite a bit. When you...
Among the biggest opportunities to consider, where beneficial and feasible: making the use of energy and materials more efficient; reducing methane emissions in fossil fuel extraction; executing so-called transition solutions, such as a shift from...
and animal waste. As a result, there are many opportunities for green technology in the area of agriculture. For example, organic farming techniques can reduce the damage due to soil exhaustion, innovations in cattle feed can reduce methane emissions, and meat substitutes can reduce the consumption...
Research indicates that the U.S. oil and gas industry emits 16.9 million metric tons of methane every year, according to the International Energy Agency.3Some of this methane is inadvertently leaked through faulty equipment or deliberately vented into the atmosphere between extractions. The Environmen...
