Biofuels are combustible fuels created from biomass.
“Firewood is the oldest bio-fuel mankind has used, now we have biogas, gasohol and many more. Carbon dioxide is produced when these burn, but as long as the trees and plants are allowed to re-grow, burning them simply helps carbon on its way round its natural cycle.
What is biogas? If we collect the faeces from humans and farm animals and place them in a ‘digester’ we can mimic what happens in a cow’s intestine, and we get biogas. There are many such digesters in use all round the world, where the gas is used for cooking and lighting and the remains are a rich fertiliser. Biogas digesters are used in most sewage works where the methane is burnt to generate electricity.
Did you know that GMO (genetically modified organisms) ingredients are found in 80% of packed foods in US? This infographic explains environmental concerns and potential health risks around GMOs, and gives some info on MSG and food labeling as well.
From its early 20th century origins selling a suspect sweetener, Monsanto has long had its hand in our food supply. And that isn’t necessarily a good thing. Let’s take a look at the company’s history and its current practices.
With an alarmingly dry winter and California reservoirs dropping fast, groundwater increasingly is keeping the state hydrated. It now accounts for about 60 percent of California’s water supply. But unlike its rivers, lakes and reservoirs, the state does not consider groundwater part of the public good. It does not regulate groundwater like it does surface water. Landowners can pump as much water as they want.
So for nearly a century, Californians have drained an incredible amount of water from the ground to grow crops and water landscaping. It is not sustainable. The water has not returned. The result is a sinking state. Here is a summary of some startling facts (Originally posted by Nathan Halverson on revealnews.org) about California’s groundwater depletion: Continue reading “California’s groundwater problem”→
Why are GMOs bad? They aren’t. They just aren’t, not intrinsically, and certainly not for your health. We’ve been eating them for decades with no ill effects, which makes sense, because a genetically modified organism is simply an organism, like every other organism, produces hundreds of thousands of proteins, but one or two of them are proteins that were chosen specifically by humans.
