A Bunch of Butterflies
Priests don’t like confetti, it makes a mess. The bride and groom rarely like rice, because it hurts. So the latest thing at weddings, at least in America, is butterflies.
What could be nicer than having a bunch of butterflies released into the air around the marriage couple? Companies are now springing up in the US to meet the new demand, but animal rights groups are concerned. How are the butterflies caught, how are they transported to the wedding and what happens to them afterwards? The wedding party thinks the butterflies fly away, but often the insect cannot survive in their new environment and die.

spring up – surgir

The Young Can’t Wait
When you are little, it’s not hard to believe you can change the world. I remember my enthusiasm when, at the age of 12, I addressed the delegates at the Rio Earth Summit. “I am only a child,” I told them. “Yet I know that if all the money spent on war was spent on ending poverty and finding environmental answers, what a wonderful place this world would be. In school you teach us not to fight with others, to work things out, to respect others, to clean up our mess, not to hurt other creatures, to share, not be greedy. Then why do you go out and do the things you tell us not to do? You grownups say you love us, but I challenge you, please, to make your actions reflect your words.”

The Secret of Success in the US.
If you wonder why Robbie Williams and Oasis have not found success in the US, just look at their teeth. Determined not to make the same mistake, the ex – Boyzone singer now–gone–solo Ronan Keating has gotten his crooked front teeth capped in order to have a perfect smile to woo American audiences. Americans approve of artists with a perfect set of teeth such as Britney Spears, and they think that bad teeth make performers less attractive – thus making consumers less prone to buy their CDs.

Global warming: Adapting to a new reality
By Elisabeth Rosenthal
As countries across Europe reduce protection of greenhouse gases in order to fight climate change, scientists and citizens are discovering that effects of warming are already upon us. Irreversible warming is already happening, they say, and will continue for a century even if polluting emissions are controlled by the Kyoto Protocol, the international treaty aimed at limiting greenhouse gases. To this end, they say, governments and citizens must prepare for a steamier future, adapting to a climate that is hotter and stormier.
The early warning signs of global warming are apparent: an increase in summer deaths due to heat waves in Europe; the northern migration of toxic algae and tropical fish to the Mediterranean; the spread of disease-carrying ticks into previously inhospitable parts of Sweden and the Czech Republic. Scientists say that global warming may be partially responsible the rising number of powerful hurricanes, like Katrina, as well as an increase in floods.
Most scientific models predict that temperatures will rise 2 degrees 6 degrees Celsius, in Europe over the next century-slightly less elsewhere in the world. And people are largely unprepared. In response to this trend, countries and politicians are starting to think changes they will have to make:
adapting to climate change, for example, French farmers are shifting to crops that better tolerate warmer temperatures;
supplying the elderly with air-conditioners, as the Italian city of Brescia is doing.
Adapting to climate change seems to be simple. However, in some cases, adaptation would be so expensive that the authorities may opt to let nature take its course.
