Practical Intro Into Sustainable Economy

Everyone’s heard of Al Gore’s Inconvenient Truth, but the world needs to address more than smokestacks and car exhausts. Below is a list of five areas necessary to build a sustainable world economy:

1. The Green Revolution brought technology to agriculture and ended imminent starvation for millions. Discrepancies in wealth, food distribution, and public policy are continuing barriers to ending world hunger, but a new barrier has emerged – diet. Counter to intuition, the world’s wealth poses the greatest threat to a sustainable food supply. World meat consumption is skyrocketing. Every pound of meat requires approximately seven pounds of grain to produce. Dr. Dean Ornish of UCSF has written and spoken extensively on the shift of the American and world diet and its impact on increasing heart disease, diabetes and obesity. New York Times’ columnist and author Mark Bittman echos this advice in his columns and practice – he limits his meat consumption to one meal a day.

Extreme Climate Patterns

The current rise in hot temperatures witnessed in different parts of the world is signs of global warming getting worse. This is evident with the recent heat waves which have seen different parts of the world receiving extremely high temperatures. Summer seasons in 1950s experienced average temperatures which were neither high nor low. In 1980s, saw a steady increase in temperatures, according to James Hansen, a climatologist at NASA’s Goddard Institute for Space Studies in New York City, who together with his co-workers crafted a report in August dubbed Proceedings of the National Academy of Sciences which revealed some glaring facts about the rising warm temperatures. In the report, Hansen declares that since 2000, the simmering temperatures have recorded a sharp increase of average summer season temperatures.

How The Amazon Creates Its Own Rain

How The Amazon Creates Its Own Rain

How The Amazon Creates Its Own RainThe Amazon rainforest is a mystery of many sorts. We’ve heard of the rare and unique flora and fauna of the place, and here’s another intriguing aspect there: the Amazon is self-sufficient in rain as well!

The technique of “cloud seeding” used by rain-starved nations to induce rain is used naturally by the fungi and trees in the Amazon to produce rain. Scientists have discovered that trees and fungi release minute amounts of potassium-rich salt which is the cause of a large amount of rain in the area. Since they deflect light from the sun, it helps in cooling the Earth too.

Normally, water vapour molecules collect around a core to form raindrops. The core can be salt spray, soot, dust, airborne organisms, droplets of chemicals from volcanoes etc. The scientist for atmospheric research studies at the German Max Planck Institute, Christopher Pöhlker says that though their studies Continue Reading

forest trees absorb water through leaves

Research now reveals that cloud forest trees absorb water through leaves

forest trees absorb water through leavesScientists from the University of California in Berkeley have now established that Tropical montane cloud forest trees not only take up water through their roots like other trees but also through their leaves directly from the clouds. Trees growing in arid areas usually find alternative means of survival and this is a classic example of one such strategy in a largely foggy region. However, the after-effect of climate change is beginning to take a toll on these trees because the very clouds they depend on for survival are diminishing.

According to Professor and senior author at the university, Prof. Todd Dawson, the backbone of the study was highlighting the plight of this unique ecosystem brought about by climate change. This study has come up with alarming findings that indicate a decline and in some cases total disappearance of animal life found in the cloud forests. specific examples include salamanders as well as frogs whose population is fast declining. This new study will have its results published in next year’s journal ecology letters but is already accessible this month online. Continue Reading

Polar Bear

Ban On International Polar Bear Trade Rejected

Polar BearA midst trepidation’s of distraction from the ever-growing problem of global warming that is posing a major threat to the whole world, an important meeting of governments tracking threats to endangered species chose to reject a international ban on polar bear trade on Thursday. The result of this rejection was a division among conservationists with some believing that the threat of extinction of largest carnivorous animals in the world is not only because of loss of habitat but also because of international trade of these animals.

There is enough reason for this panic as polar bears are expected to be in the frontline of those animals that will be disadvantaged because of polar ice caps that are fast melting. However, the spotlight of the raging debate among the 178 CITES member nations held in Bangkok was on the extra danger that was posed to these animals because of international trade.

Nesting Spots For Turtles

Nesting Spots For Turtles

A New Map Reveals That Nesting Spots For Turtles Cut Off By Various Conflicts

Nesting Spots For TurtlesTurtle nesting experts today said that conflict has cut off most of the potential nesting spots for turtles and the spots include remotely placed locations as revealed by a new map for turtle nesting spots.

The sea turtles are having it hard as they have already been endangered by activities such as coastal development and fishing and are now in more danger as changes in the climatic conditions are threatening their reproduction. This is because the turtles need very special conditions to be able to reproduce and small alterations in the moisture and heat level are enough to prevent their eggs from hatching. Researchers say that it is now very important for the sea turtles to be able to know where conditions are optimum for them to lay eggs as the current global warming has made popular nesting spots useless due to the fact that they are either too hot or dry for use. The availability of some nesting spots that have the necessary conditions for the turtles to nest would be an ideal start show how global warming changes habitats. Continue Reading

Atmospheric Carbon Levels

Atmospheric Carbon Levels

Atmospheric Carbon LevelsThe level of carbon dioxide in the atmosphere is hitting new highs. Scientists are reporting that the level of concentration is gradually increasing and chances are it will exceed the 400 parts per million (ppm). This is a level that has not been experienced on earth for around 4 million years. Researchers at the Mauna Loa Observatory have already recorded highs averaging 399 ppm. This raises concerns as it depicts a steadily increasing trend of the levels of the most imperative heat trapping gas in the earths atmosphere.

Considering the fact that humans had not evolved more than three million years ago, this new records are quite alarming. In addition, the Mauna Loa Observatory has been recording some averages exceeding 400 ppm during some hours. As their researchers indicate carbon levels tend to increase in mid May. This is a depiction that the world is yet to hear of new records in the next few days or weeks. Continue Reading

Australia’s Tropical Wetlands

Northern Australia has a large area of bio diverse tropical wetlands which are important for the ecological health of the region. As pressures for development increase, however, the precious ecosystems of the wetlands are threatened. Human encroachment as well as the inadvertent introduction of invasive plants and animals have caused adverse changes in the delicate balance required for healthy wetlands. Native plants and indigenous peoples are in danger of being overrun, and the ecologically important functions of the wetlands as a filter for waters in the area are threatened.

Lead Poisoning And Its Effects

old-mining-broken-hill-broken-earthLead is an element that has proven to be extremely harmful to the health of people when inhaled or ingested. The effects are even more detrimental to the neurological system in the cases of children under the age of 6.
One can be exposed to lead in the following ways; inhalation of particles containing lead in the form of dust in the air or soil, ingestion of foods containing the element from water or soil and ingestion of water that is contaminated by lead in the form of paint chips, soil or dust. Lead poisoning has no unique signs and should be treated with extreme caution. Early symptoms include irritability, reduced attention span, loss of appetite, fatigue, insomnia and stomach discomfort. These symptoms can lead to even more drastic effects such as:

Fossil vs. Renewable: Energy's Future Today

Fossil fuels are produced by the decomposition of dead organisms, buried for millions of years. They produce greenhouse gasses and other pollutants, and their continued use could leave mankind as extinct as those decayed fossils. The earth does not hold an infinite amount of these fuels. Barring our extinction, the supply of fossil fuels will eventually run out, though demand for energy never will. An energy source is needed that is both eco-friendly and renewable. In other words, one that doesn’t pollute, and will never run out.

Monitoring Software

The Internet can be tricky for parents to deal with because kids often need to use the Internet for school, but parents parents are often worried about the various activities that their children might be engaged in. Peer-to-peer file sharing can lead to lawsuits and even a criminal prosecution. Some teens might engage in activities online that are embarrassing to the family or may lead to viruses or hackers accessing the computer. Fortunately, there are various forms of monitoring software that can offer parental control.

Monitoring software can also be very helpful when parents are trying to learn what their children are up to, such as whether they are attending class or doing their homework.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
