The once-exotic bird is becoming a notorious pest as it enjoys a population
explosion in many London suburbs.
"There is wide agreement that the Adams and Eves behind the current
population boom did not fly here from Asia or Africa but escaped from
British pet cages or were intentionally released by their owners. The great
mystery is what allowed the parakeets to procreate with such phenomenal
success just in the past decade."

"Most glaciers are melting, they are retreating; some glaciers, like the Siachen glacier, are advancing. But overall one can say incontrovertibly that the debris on our glaciers is very high, the snow balance is very low. We have to be very cautious because
of the water security, particularly in north India, which depends on the health of the Himalayan glaciers," says Jairam Ramesh, Minister for Environment, India.
The new National Institute of Himalayan Glaciology is based in Dehradun, in Uttarakhand, and will monitor glacial changes and compare results with those from glaciers in Pakistan, Nepal and Bhutan.
India has launched the Indian Network on Comprehensive Climate Change Assessment (INCCA)," the Minister said. It will bring together 125 research institutions throughout India, work with international bodies and operate as a "sort of Indian IPCC," he added.
The body will publish its own climate assessment in November, 2011, with reports on the Himalayas, India's long coastline, the Western Ghat highlands, and the north-eastern region close to the borders with Bangladesh, Burma, China and Nepal.

Mountaintop removal coal mining is changing the American landscape on a scale that is hard to comprehend unless you see it from the air. Anyone who has ever flown in a small aircraft over southern West Virginia or eastern Kentucky will never forget the experience
of seeing the massive scale of destruction - mountain after mountain blown up and dumped into valleys as far as the eye can see. Mountaintop removal affects more than mountains and streams, however; it is threatening to displace and destroy a distinctly American
culture that has persisted in the Appalachian Mountains for generations. Appalachian people working to save their communities have long dreamed of ways to fly reporters, decision-makers, and thousands of other Americans over the Appalachian coalfields to see
this destruction first hand - and then to visit their communities to hear stories of people who endure the consequences of what some have called "cheap energy."

The Jacaranda tree is in full bloom
Spring is here with cool mornings and evenings. What we call, beautiful weather. When spring comes with a tinge of cold, rather than an abrupt change from cold to hot, the colours are vivid and rare beauties bloom. The month of March, with cricket in every
one's mind and can the blues be far behind?
The above flower is called bachelor button and it is mostly blue in colour.
More bachelors among pink flocks. The iris lily forgot to bloom last year as the summer came swift and strong. But this year one eagerly awaited the blooms hiding inside wrinkled leaves of the lily.
 
But the highlight of the early spring is always the appearance of Common jay butterfly, feeding on the nectar of "Curry Leaves" flowers.
The Blue pansy also appears sucking in wet mud and taking a break on the Ashoka leaves.
The crowning glory of the season this year, was of course our own blue cricket team who lifted the world cup after 28 years!

Cancer: Normal cells in the body multiply only when the body needs and die when body does not need them. Cancer appears when the growth of the cells became out of control and cells divide non stop again and again. The cancerous cells (which are also known
as malignant cells) forgot how to die. Besides human, animals and other living organisms can get cancer. Cancer can develop almost in every organ or tissue such as colon, breast, lung, skin, bones, or nerve tissues. The various causes of cancer include-1.
drinking excess alcohol. 2. genetic problem. 3. obesity. 4. radiation. 5. viruses. 6. excessive sunlight exposure.
But the cause of many cancers remain unknown. Lung cancer is the most common of all cancer- related death. Most of the cancers are diagnosed by biopsy.
Cataracts: Clouding of the lens in eye is referred to cataracts. It affects vision and are very commonly found in older people. cataracts generally grow slowly. some symptoms of cataracts are- 1. Blurry or/and double vision. 2. colors seems faded. 3. Vision
not so well at night. 4. glare.
At first stage, some protection measures can help, like- using anti- glare glasses, use of sun glasses, brighter light. Surgery is also done by removing the cloudy lens by replacing it with artificial lens.

Radioactivepollution is very important environmental problem. The effects o radioactivepollution may represent significant health risk to
human and other organisms.
Ultraviolet(UV) light is actually electromagnetic radiation with very short wave length(i.e; shorter than that of visible light). UV ray damages
the cells of corneaand ultimately results to blindness. It also causes blisters and redness o theskin (skin cancer) by damaging the cells of the skin.
The effectsof radioactivity generate damage to the gene pool, the genetics of all livingspecies. Genetic damage from radiation effects over
life time and generations.
The firsteffect of radioactive pollution was noted in the early twentieth century(1909). The miner who were working in uranium mines, suffered
from skin burnand cancer. Some of the major biomedical effects of radiation are well known inhistory. During Second World War in Japan (1945), many people were died due toradioactivity of the atom (atomic explosion). Another prominent radioactivedisaster was
1984, Chernobyl, where an atomic power station was met with anaccident.

Thesubstances which have adverse effects on living organisms and environment, asknown as toxic substances. A toxicsubstance has the ability to cause
systemic damage to living organism. Toxic substancesare resent in air, soil, water and in other living things. They can enterinside body in many ways, like; - through ingestion- by eating or drinking,through inhalation- by breathing, through contact with the
skin- by absorption,through injection- from syringe or from other poisonous insect or snake bite.
Toxic substancesare mainly of three categories. Chemical, biological and physical. Chemical toxicsubstances include (a) inorganic substances like
lead, mercury, asbestos, hydrofluoricacid, chlorine (gas) and (b) organic substances like methyl alcohol, medicineand poison from living things.
The dosageor concentration of the toxic substances is very important. Or properfunctioning of organism, many substances may be essential at low doses,
butthat particular substance can be dangerous at higher doses. For example,manganese is so important for an pregnant woman, that a deficiency of manganeseduring pregnancy reduce growth and can cause mortality of the offspring, whereas workers exposed to high
levels of manganese (manganese mines) sufferingbrain damage that causes memory impairment, disorientation and acute anxiety.
