More than 200 reindeer have died of starvation on the Norwegian archipelago of Svalbard, with scientists blaming their deaths on climate change. The wild deer carcasses were found on the Arctic islands this summer by researchers from the Norwegian Polar Institute (NPI), which said it had never logged so many deaths at once in 40 years of monitoring the animals’ population level. “It’s scary to find so many dead animals,” project leader Ashild Onvik Pedersen told state broadcaster NRK. “This is an example of how climate change affects nature. It is just sad.”
Svalbard’s capital Longyearbyen, the northernmost town on earth, is thought to be warming quicker than any other settlement on the planet, climate scientists warned earlier this year. The milder temperatures in the region led to unusually heavy rainfall in December, leaving a thick layer of ice when the precipitation froze. This meant the reindeer could not dig through the hardened tundra to reach the vegetation they graze on in their usual pastures, the NPI said. Svalbard’s reindeer have been observed eating seaweed and kelp when food is scarce, but these are less nutritious and cause them stomach problems.
A relatively high number of calves born last year increased the death toll, as the youngest and weakest are often the first to die in harsh conditions. “Some of the mortality is natural because there were so many calves last year. But the large number we see now is due to heavy rain, which is due to global warming,” said Ms Onvik Pedersen.
A team of three scientists spent 10 weeks investigating population of the Svalbard reindeer earlier this year. Researchers warned the decline of reindeer would cause unwanted plant species, currently kept in check by the animals’ grazing, to spread across Arctic ecosystems in Europe, Asia and North America.
Arctic reindeer and caribou populations have declined 56 per cent in the last two decades, a report by the National Oceanic and Atmospheric Administration said last year. The report said food security was partly to blame for falling herd numbers, while warmer summers could also put the animals at greater risk of diseases spread by flies and parasites. The average temperature in Longyearbyen has risen by 3.7C since 1900, more than three times the global average increase of about 1C. In 2016, the entrance to the town’s “Doomsday” seed vault – which stores specimens of almost all the world’s seeds – was flooded following heavy rainfall.

In this era of increased global warming and diminishing fossil fuel supplies, we must begin to put a greater priority on harnessing alternative energy sources. Fortunately, there are a number of readily available, renewable resources that are both cost- effective and earth – friendly. Two such resources are solar power and geothermal power.
Solar energy, which reaches the earth through sunlight, is so abundant that it could meet the needs of worldwide energy consumption 6,000 times over. And solar energy is easily harnessed through the use of photovoltaic cells that convert sunlight to electricity. In the us alone, more than 100, 000 homes are equipped with solar electric systems in the form of solar panels or solar roof tiles. And in other parts of the world, including many developing countries, the use of solar system is growing steadily.
Another alternative energy source, which is abundant in specific geographical areas, is geothermal power, which creates energy by tapping heat from below the surface of the earth. Hot water and steam that are trapped in underground pools are pumped to the surface and used to run a generator, which produces electricity. Geothermal energy is 50,000 times more abundant than the entire known supply of fossil fuel resources and as with solar power, the technology needed to utilize geothermal energy is fairly simple. A prime example of effective geothermal use in Iceland, a region of high geothermal activity where there are over 80 percent of private homes, are heated by geothermal power.
Solar and geothermal energy are just two of promising renewable alternatives to conventional energy sources. The time is long overdue to invest in the development and use of alternative energy on global scale.

Homeopathy, the alternative therapy created in 1796 by Samuel Hahnemann, and now widely used all over the world, is based on the belief that the body can be stimulated to heal itself. A central principle of the “treatment” is that “like cures like”, meaning a substance that causes certain symptoms can also help to remove those symptoms. Medicines used in homeopathy are created by heavily diluting in water the substance in question and subsequently shaking the liquid vigorously. They can then be made into tablets and pills. Practitioners believe that the more a substance is diluted in this way, the greater its power to treat symptoms.
However, in a new study, a working committee of medical experts at Australia’s National Health and Medical Research Council (NHMRC) has claimed that homeopathic medicines are only as effective as placebos at treating illness. Their research, involving the analysis of numerous reports from homeopathy interest groups and the public, concluded that there is no reliable evidence that homeopathy works. Moreover, researchers uncovered no fewer than 68 ailments that homeopathic remedies had failed to treat, including asthma, sleep disturbances, cold and flu, and arthritis.
As a result of the findings, the NHMRC is urging health workers to inform their patients to be wary of anecdotal evidence that appears to support the effectiveness of homeopathic medicine. “It isn’t possible to tell whether a health treatment is effective or not simply by considering the experience of one individual or the beliefs of a health practitioner” says the report. Experts believe that most illnesses said to have been cured by homeopathy would be cured by the body on its own without taking the medicine. Apparently, many illnesses are short-lived by their very nature which often leads to people believing that it is the homeopathy that cures them.
A more serious matter is highlighted by Professor John Dwyer of the University of New South Wales. As an immunologist, he is concerned about homeopathic vaccinations on offer for diseases such as HIV, tuberculosis, and malaria, none of which he considers effective. According to Professor John Dwyer, the concept that homeopathic vaccinations are just as good as traditional vaccinations is delusion, and those who believe it are failing to protect themselves and their children.
