As a result of deforestation, only 6.2 million square kilometers remain of the original 16 million square kilometers of forest that formerly covered Earth. Apart from adveserly impacting people’s livelihoods, rampant deforestation around the world is threatening a wide range of tree species, including the Brazil nut and the plants that produce cacao and açaí palm; animal species, including critically-endangered monkeys in the remote forests of Vietnam’s Central Highlands, and contributing to climate change instead of mitigating it (15% of all greenhouse gas emissions are the result of deforestation).

While the world’s forest cover is being unabashedly destroyed by industrial agriculture, cattle ranching, illegal logging and infrastructure projects, Thailand has found a unique way to repair its deforested land: by using a farming technique called seed bombing or aerial reforestation, where trees and other crops are planted by being thrown or dropped from an airplane or flying drone.

The tree seed bombing in Thailand is one of the greatest examples of ‘Conscious Entrepreneurs’ or ‘Spiritual Entrepreneurs’ out there right.

We knew this was going to happen. Just still neat to read about it.


(Phys.org) —NASA is planning to launch a milestone experiment involving growing plants on the moon. The target date is 2015, when the agency will deposit plants on the moon’s surface. The initiative is being driven by the Lunar Plant Growth Habitat team. They intend to use coffee-can sized containers designed to protect the plants against harsh elements of the climate, and will also provide cameras, sensors, and electronics in order to relay information about how the plants fare back to earth. NASA’s plan is “to develop a very simple sealed growth chamber that can support germination over a five to-ten day period in a spacecraft on the Moon.”

What will NASA try to grow? The containers will attempt to grow turnip, basil and Arabidopsis The latter is used often in plant research; Simon Gilroy, University of Wisconsin-Madison botany professor, has referred to the Arabidopsis as “the lab rat of plant biology.” Will the life forms survive the lunar surface? NASA’s plan is to find some answers when this “self-contained habitat,” which will have a mass of about 1 kg and would be a payload on a commercial lunar lander, is on the , How it gets there is another interesting side of the story, because NASA is taking advantage of a parallel event to save costs significantly.

“How can we send plants to the Moon soon? Hitchhiking. Thanks to Google, there are many potential rides to the moon in the near future, with commercial spacecraft companies competing to collect the Google Lunar X-Prize in 2015,” according to NASA. (The prize is in reference to what is called the Google Lunar XPRIZE, an incentive to safely land on the surface of the Moon. In order to win the , a private company must land safely on the surface of the Moon, travel 500 meters above, below, or on the , and send back two mooncasts to Earth, said Google. Teams may also compete for bonus prizes such as exploring lunar artifacts or surviving the lunar night, and can be awarded prize money earlier by completing terrestrial or in-space milestones. Everything needs to be completed, though, by December 31, 2015.)

Recognizing the importance of biofuels to energy and climate security, the U.S. Department of Energy has announced up to $90 million in project funding focused on designing, constructing and operating integrated biorefinery facilities. The production of biofuels from sustainable, non-food, domestic biomass resources is an important strategy to meet the Administration’s goals to reduce carbon emissions and our dependence on imported oil.

Project Development for Pilot and Demonstration Scale Manufacturing of Biofuels, Bioproducts, and Biopower is a funding opportunity meant to assist in the construction of bioenergy infrastructure to integrate cutting-edge pretreatment, process, and convergence technologies. Biorefineries are modeled after petroleum refineries, but use domestic biomass sources instead of crude oil, or other fossil fuels to produce biofuels, bioproducts, and biopower. They convert biomass feedstocks—the plant and algal materials used to derive fuels like ethanol, butanol, biodiesel and other hydrocarbon fuels—to another form of fuel or energy product. This funding will support efforts to improve and demonstrate processes that break down complex biomass feedstocks and convert them to gasoline, diesel and jet fuel, as well as plastics and chemicals.

“The domestic bio-industry could play an important part in the growing clean energy economy and in reducing American dependence on imported oil,” said Lynn Orr, DOE’s under secretary for science and energy. “This funding opportunity will support companies that are working to advance current technologies and help them overcome existing challenges in bioenergy so the industry can meet its full potential.”

I wonder if this would qualify as a turing test.

“I have been accused of being a computer,” says TA Lalith Polepeddi, a computer-science master’s student who was needled for responding to messages with lightning speed. “I don’t take it personally.”

File this under definitely not good: global warming is depleting the oceans of oxygen. You know, that little molecule that we, along with all other complex life forms, require in order to breathe and therefore live.

The reason is simple. According to basic thermodynamics, cold water can hold more dissolved gases than warm water. As our ever-warming atmosphere heats the surface of the ocean, the oxygen content starts to fall. Also, as water warms, it expands and gets lighter. This makes it less likely to sink, which in turn reduces the transport of oxygen from the atmosphere into the deep ocean.

All of this is well-established science. It’s also understood that the oxygen content of the ocean varies all the time due to changes in weather, seasons, latitude, and longer-term climate patterns like El Niño. But a study published this week in Global Biogeochemical Cycles is the first to show that the oxygen content of the world’s oceans is now falling thanks to climate change.

The United States is transitioning from a primary reliance on fossil fuels to greater use of sustainable natural and nuclear energy sources. There are two reasons for this transition. The first reason is that the abnormally high and increasing level of atmospheric carbon dioxide has created scientific uncertainty and concern as to the detrimental impact this may have on the environment and, consequentially, human civilization. Almost certainly, this abnormal level is due to anthropogenic causes linked to the tremendous expansion in the human population since the early 1700s, the growth of human civilization (e.g., agriculture and industrialization), and the increasing use of fossil fuels. Although fossil fuels have enabled worldwide progress in elevating the standard of living, most of the world’s nations have reached the conclusion that the world should transition entirely to sustainable energy by 2100 (see “The Paris climate agreement and space solar power”, The Space Review, February 29, 2016). It is, however, very important to manage this transition carefully to avoid economic hardship or energy deprivation.

While the United States has large remaining fossil fuel resources, only some are technically recoverable with current safe, legal, and profitable extraction methods. The remaining known and yet-to-be-discovered domestic technically recoverable fossil fuels are inadequate to sustain US fossil fuel energy needs to the end of this century, especially given likely continued immigration-driven US population growth (see “US fossil fuel energy insecurity and space solar power”, The Space Review, March 7, 2016). While the United States has an ethical environmental obligation to end its use of fossil fuels by the end of the century, the reality of having inadequate oil and natural gas resources makes the urgency of transitioning successfully to new sustainable energy sources a clear matter of national energy security. This warrants federal government leadership and strong American private sector engagement.

Unfortunately, due to its large and growing population and per capita energy needs, the United States lacks sufficient suitable land to utilize terrestrial renewable energy to replace fossil fuels. (see “US terrestrial non-fossil fuel energy vs. space solar power”, The Space Review, March 14, 2016). While the United States will utilize terrestrial domestic renewable energy to the extent it is politically acceptable, many factors will likely limit their scale-up. The expansion of nuclear fission energy is also not a satisfactory approach, given the large number of reactors needed. These factors lead to the conclusion that only space-based sustainable energy, such as space solar power, will enable the United States to practically transition away from fossil fuels.

If you dig deep enough into the Earth’s climate change archives, you hear about the Palaeocene-Eocene Thermal Maximum, or PETM. And then you get scared.

That was a time period, about 56 million years ago, when something mysterious happened — there are many ideas as to what — that suddenly caused concentrations of carbon dioxide in the atmosphere to spike, far higher than they are right now.

The planet proceeded to warm rapidly, at least in geologic terms, and major die-offs of some marine organisms followed due to strong acidification of the oceans.
