Comments Off on Climate change is killing reindeer in the Arctic

A new Arctic Report Card from the U.S. National Oceanographic and Atmospheric Administration (NOAA) has revealed that the wild reindeer and caribou populations have plummeted by more than half over the last two decades. According to the report, the impact of climate change in the Arctic has resulted in the reindeer population falling from 5 million to 2.1 million. The report found that the weather patterns and vegetation changes in the Arctic tundra have had a major negative impact on the reindeer, and the wild herds in northern Canada and Alaska have been hit the worst, with some of the herds shrinking by more than 90 percent. Related: Norway rejects wind farm in favor of wild reindeer “We see increased drought in some areas due to climate warming , and the warming itself leads to a change of vegetation,” said professor Howard Epstein, an environmental scientist from the University of Virginia. Epstein was one of the scientists involved with the research for the new report, and he explained that the reindeer eat lichen, which grows at ground level. But the warming temperature has led to taller vegetation, and it is “out-competing” the lichen. The warmer climate has also meant more bugs in the region, and that results in the reindeer having to spend their day getting the insects off of them or hiding from the insects. Increased rain has caused a problem, because it falls on snowy ground and creates hard layers of ice covering the tundra. This makes it difficult for the animals, because they can’t push their noses through the ice to get to their food. As for what can be done about the problem, the BBC reported that reducing carbon emissions and limiting temperature increases needs to be done on a global scale. Not only will this help the reindeer, but it will also decrease extreme weather events around the world. + NOAA Via BBC Image via U.S. Department of State

Comments Off on 5 ways bacteria can be used to help better the environment

Mohit Sharma: Bacteria Not all bacteria are harmful!! Whenever anyone mentions the word bacteria, all we can think about the diseases that are associated with them. True that bacterium can be harmful and can cause many diseases like tetanus, typhoid, leprosy and cholera. But, not all of the bacteria are harmful and dangerous for humans. Some of the bacteria have been used for benefit of mankind as well. Let us look at five ways in which these microbes help the environment. 1. Cleaning oil spills Oil Spills Some bacteria eat them up as food!! Some type of bacteria are very helpful in cleaning up oil spills. Crude oil is one of the rich sources of food for bacteria. Also, when an area is filled with a large amount of hydrocarbons (in the form of oil spills, that is crude oil) and is supplied with nutrients like nitrogen and phosphorous, it becomes breeding ground for bacteria. Once they clean up the spilled oil these bacteria die a natural death and do not cause any harm to the natural environment. Bacteria have been effective oil zappers in many oil spills like deep water horizon spill in the Gulf of Mexico and Delaware oil spill in Pennsylvania. 2. Cleaning pollution and generating electricity Shewanella a bacteria that creates electricity!! For a long time scientists have been independently researching to find bacteria that can help in cleaning up pollution and bacteria that can generate electricity. Now they have found some bacteria that can do the both at the same time. A bacterium known as Desulfitobacteria can simultaneously breakdown pollutants like Printed Circuit Boards and produce electricity. Another bacterium known as Shewanella which grows in low oxygen environment of deep seas has the capability to produce electricity. These bacteria have the capability to produce continuous electricity provided they are constantly being fed. 3. Metabolizing methane into methanol Methanotrophs bacteria that metabolizes Methane!! One of the biggest problems our planet is facing today is the problem of global warming. It is caused due to emission of greenhouse gases from various processes and activities like burning of fuel for power generation, transportation, etc. One of the major gases responsible for global warming is methane. Scientists have been researching an effective way to metabolize methane and reduce its quantity in atmosphere. They have been able to find that certain types of bacteria metabolize methane in presence of heavy metals like copper and convert it into methane. These bacteria have three advantages. Firstly they remove methane from atmosphere, secondly the help in reducing the quantity of harmful heavy metals which can cause harm to humans and thirdly the methanol produced can be used as a fuel. Bacteria that metabolize methane are known as methanotrophs. It has been suggested that they can be used by venting methane gas emissions through filters which contain methanotrophs, and the methanol produced can be stored in a container attached for future use. 4. Converting newspaper to biofuel Nespapers they could be your next biofuel!! With threat of running out of fossil fuel for energy consumption, this could be answer to world’s energy needs. A particular type of bacteria known as TU-103, was discovered at Tulane University, New Orleans (by David Miller, associate professor). This bacteria converts cellulose into butanol. Cellulose is most widely available organic material in the world. It can be found practically everywhere from paper, glass, leaves, corns, to bagasse, a fibrous leftover material in production of sugar from sugarcane. This discovery can have several ramifications. It could help in reducing the cost required to produce biofuels, it can take pressure of farmers and arable lands where crops are produce specifically to produce biofuels, it can decompose a lot of waste material hence lesser landfill space would be required and the harmful emissions produced from butanol are less as compared to petrol or gasoline. 5. Treating depression and anxiety Depressed? take a dose of probiotic bacteria today!! Bacteria have been living inside us symbiotically and assisting us in many vital functions ranging from dental health to digestion. These bacteria are known as probiotic bacteria. Recently researchers at McMaster University in Canada have found another useful function of these bacteria. They fed a group of mice with a type of bacteria known as Lactobacillus rhamnosus JB-1 and another group just broth. Later they found that the mice who had ingested JB-1 bacteria showed fewer anxiety, depression and stress related behaviors and had a significantly lower level of stress-induced hormone, corticosterone than the mice who were fed only broth. This could be a foundation stone to a new kind of treatment for psychic disorders.

Comments Off on Five biodegradable containers that are better for the eco system

Sreejan Guha Niyogi: With the increasing threat to ecosystem, the necessity of biodegradable containers is felt all over the world. Though people are aware of the threat, but still there is a need to create mass awareness about the biodegradable containers that are better for ecosystem. In our daily life, we use many containers which are harmful to wildlife and nature. The commonest example is plastic bag. Not only plastic bags, but cans, plastic bottles, cans, paper cups if not recycled can end up in degrading our ecosystem. Hence, the need for an alternative exists and biodegradable containers can be a good substitute for day-to-day used materials. Since biodegradable products are made up of natural ingredients which decompose easily, less energy is required to recycle them providing faster and more efficient production. Also, biodegradable products does not produce toxin. Biodegradable plastics are microwavable; completely freezer safe and can withstand 120 to 200 degrees Fahrenheit. Owing to the above mentioned advantages, one should definitely opt for biodegradable products instead of plastics. There are many biodegradable products which can be used in daily life for the betterment of the ecosystem. 5 examples of biodegradable containers that are better for the environment are mentioned below: 1. Alternative for plastic water bottles Water bottle is an important part of our daily life. And Plastic water bottles are the most common material that we use for carrying water everyday. Hence, there is a need for its alternative in order to preserve our ecosystem. The biodegradable substitute for plastic water bottles can be stainless steel or aluminum bottles. In case, you don’t have choice but to carry plastic bags, bio-friendly water bottles can be better alternative which many companies are manufacturing these days. For example, Canada’s red leaf. 2. Paper/Plastic Cup Alternative It is very convenient to use disposable paper/plastic cups in picnics and parties. Also, these are used in such a huge quantity worldwide, the most common place is the tea or coffee shop, ice cream parlor etc. But, these disposed materials form a major portion in the landfills and can be threat to the ecosystem if not recycled. Jelloware glasses can be an alternative for these disposable bags. Jelloware glasses consist of seaweed extract. These glasses can be thrown in the garden as it helps in the growth of the plants by adding nutrition. 3. Take-out containers substitute Everyone’s household contains minimum 3-4 take-out containers made of plastic which is hazardous to our ecosystem balance. The Polystyrene take-out containers definitely need to be replaced by ecofriendly alternatives as thousands of these take-out containers are disposed worldwide which poses threat to our ecosystem. The alternative to these containers are compostable and biodegradable containers which are manufactured using sugarcane or corn rather than petroleum and other chemicals. 4. Gardening pots We cannot curtail our interests due to ecosystem imbalance. However, instead of using plastic gardening pots, one can use alternative biodegradable pots for gardening. Now it is easy to grow food in containers that not only are hygienic and fully biodegradable, but are also beautiful to look at. So, for those who are interested in gardening, they can carry out their interests without using plastic and without harming the ecosystem anymore. 5. Poop bags Poop bags are used by people who keep pets in their households. Hence, you can imagine the use of poop bags in quantity worldwide. Nowaday, in most of the households, we can find pets worldwide. Hence, environment friendly poop bags are also required as a substitute for plastic puppy poop bags. While walking out with your dog, opting for biodegradable bags simply makes more sense than plastic bags if you think with a broad outlook in terms of saving our ecosystem. So as we can see, with the use of these containers we can do our bit in protecting the environment from further damage. These biodegradable containers should replace the harmful ones as soon as possible.

Comments Off on How to make a solar water heater for less than $5

Bipin Bhaskaran Nair: solar heater a detailed description of heater One of the solutions we can consider for reducing the consumption of electricity is the use appliances running on alternative energy. One such utility is a solar water heater. The conventional nichrome immersion rod or copper core water heaters consume about 250 to 500 watts of power. To substitute them quickly and the smallest possible expense, let us see how a solar water heater can be put together for less than $5. It can be done by using only household materials and easily available materials. The water heater is a DIY appliance that can be built at home. By using such a solar thermal water heater, power used for heating water is conserved. In short, you will get hot water without using up electricity and during all seasons. Let’s see how to build a solar water heater at home: Difficulty level: Easy Time required : 2 hours. Resources required: A bucket of 50 litre capacity. Glass clay. It is available in almost all paint shops. Black paint and brush. Pipe for transporting water Estimated cost: Bucket. It easily available at home. If not, it can be purchased for a small price. Glass clay – 86 cents. Glass pane – Can be bought from a mirror shop for $3. Paint brush – $2 approx Black paint – $2 approx Pipe – As per the length needed. Instructions for making the solar thermal water heater: Take a bucket and rinse it with water. Make sure no dirt or soap remains inside it. Unwanted particles may create problems in heat absorption, thus reducing its efficiency. They may dirty the water too. cut bucket a bucket is cut in half Cut the bucket through an angle from the top, as shown in the figure. The mirror which you buy from outside should be of the same profile as that of the mouth of the bucket. Cut a small hole on one side though which you can insert the pipe. Cut another hole at the extreme bottom for taking out water. Paint the inside of the bucket with black colored paint. This is done because the color black is a good absorber and retainer of heat. Place the mirror on the bucket and apply glass clay all the way around it. Keep it in the sun till it dries and hardens up. Draw a pipe that it reaches the bathroom from the roof. The pipe should be the right length. Cover it with glass clay. Connect the pipe to one of the taps. The solar water heater on a budget is ready. Instructions for using the solar thermal water heater: Insert a pipe through the hole on the side and fill the bucket with water. Cover the hole with a piece of cloth. Check the path of travel of the sun from your place of residence. That is, check the path of the sun travels in from 7 am to 1 pm in the afternoon. It is during this time period, that the most amount of usable heat will be available for the solar thermal water heater. Keep the glass covered side towards the sun. Leave it undisturbed for 3 hours. Open the tap and hot water will be at your disposal. Frequently asked questions: Why did we put a pipe all the way from the roof to the bathroom? This is done to ensure that you do not have to do the strenuous task of carrying the bucket to the roof and back to the bathroom. When efforts are being done to make anything, why not make it more convenient as well? Why did we paint the bucket black? According to theories in thermodynamics, a black-body is a good absorber of heat. So the water will heat up without needing any electricity. In fact, it is the same amount of heat that we derive from nichrome coil of an electric heater. Why did we cover it with a glass plate? It is done for two purposes. Firstly, glass permits reflection and transmission of light, but not of heat. So the heat gets trapped. Secondly, it prevents dust, dirt and unwanted matter from entering the water.

Comments Off on Smart Meter Opt-Out Bill Introduced In California

Photo by PGEgreenenergy via Flickr Creative Commons Several utilities in California have been installing smart meters like crazy across the state, though none with as much attention as Pacific Gas & Electric. The utility has made great strides in installations, but has at the same time drummed up a lot of discomfort and outright disdain from consumers in some communities who feel that the smart meters pose a health risk as well as a privacy concern. This concern is why Assemblymember Jared Huffman introduced a bill that would requir…
