Read the following passage carefully.
There are ways and ways of tackling a problem, but governments all over
the world prefer only the one from the old style book; the carrot and stick
system.The latest addition to this style of governance comes from the
Taiwanese government. Alarmed at the rising obesity levels in the island,
the government plans to introduce a ‘fat tax’. The Apple Daily , no pun
intended here, has reported that the Taiwanese Bureau of Health Promotion
is in the process of drafting a special tax on foods that are seen as unhealthy,
like sugar, candy, cakes, fast food and alcohol. The funds generated from
this tax on junk foods will go to finance Health awareness programmes and
bankroll the island’s health insurance programmes.
Taiwan is not the only one in this fight against fat; in Britain recently, there
was a proposal to introduce chocolate fat tax. But the plan, thankfully, did
not manage to get the British Medical Association’s approval.
Later, a British doctor correctly said that such taxes on junk food only lead
to lighter wallets, and not thinner waist. When did any tax encourage us into
giving up so –called harmful habits? Every day we are swamped with
reports about research that enlightens us about the negatives of everything
that is available on this earth. Yes, junk food is bad. But then what is pure?
Let’s get that debate right first. Meanwhile, let not such matters spoil the
holiday season for us. Eat, drink and make merry! Everything in moderation
is okay. Isn’t life all about choices?

Too Hot to Handle!!!
A two degree rise in the average global temperature is considered the danger line beyond which climate
change will have intense impacts. A new research by climate scientists at the Indian Institute of Science
says India will experience a 1.7 to 2 degree Celsius rise in temperatures as early as the 2030s. The study
also projects that precipitation in India is likely to increase by 4 to 5% by the 2030s.
Such a rise in temperature in India means extreme warm periods across the country. These projections
are made under a ‘business-as-usual’ scenario which means if the world’s green house gases emissions
continue to pollute at the current levels.
Many scientists feel that India is more vulnerable to such a climatic disaster because of a variety of
reasons like our vast size and presence of hot spots like the Himalayas and the coastal areas. Then there
is poverty. The poor are not resilient enough to deal with intense impacts like very warm periods or
even floods. That’s why its time we reacted faster to this impending disaster.
