Ten Ways to Save the World

- Adam Clare

There are many ways we can save the world and some may sound crazier than others. The independent has complied ten ways to save the world that range from easy to the hard.

Rethink cars

Motoring could be revolutionised if cars were marketed like mobile phones – in a manner that would cut carbon dioxide and reduce the cost of driving. Motorists would get subsidised – or possibly even free – electric cars in the same way that customers currently get mobile phone handsets. In return, they would take out a contract for miles, rather than minutes, entitling them to get power either by plugging in to recharging points (at home, in car parks or on the street) or exchanging batteries at filling stations. The idea is the brainchild of a thirty-something former dot-com entrepreneur, Shia Agassi, who believes it would halve motoring costs. It sounds too good to be true, but Israel, Denmark, Hawaii and San Francisco are already starting to put the system in place – and even Gordon Brown has toyed with the idea. But to tackle climate change properly, the electricity has to be provided by renewable sources or nuclear power rather than fossil fuels.

Embrace scum

Slimy scum could prove our saviour, as algae are emerging as one of the most promising and environmentally friendly sources of biofuel. Algae can grow extraordinarily fast, doubling in weight several times a day. They produce at least 15 times as much fuel per hectare as conventional crops like corn or oilseed rape, and do not take up farmland needed to grow food; they can be grown in lakes, the sea or even in the process of cleaning polluted water. Algae take three times their own weight of carbon dioxide from the air while growing, and the fuel they produce packs much more power for its weight than other biofuels. It is therefore being developed as a potential carbon-neutral way of fuelling aircraft: Air New Zealand has already mixed it with ordinary jet fuel for test flights. Cars have run on pure algae biofuel, and big oil companies are investing in it.

Tea Drinking Women Lower Chances of Ovarian Cancer

Another study has come showing the benefits of tea. A recent study looks at the how tea lowers the risk of ovarian cancer.

It showed those who drank two or more cups of tea daily had a 46 per cent lower risk of the disease compared with those who never or seldom drank tea.

Alex Ford, chief executive of The Eve Appeal, which supports patients with gynaecological cancers, said women should be aware of the signs of ovarian cancer, especially those over 50.

She said: ‘Traditionally, early diagnosis was difficult as experts didn’t agree on the symptoms and they are easily mistaken for other, much more common and less serious conditions.

You Can Improve Your IQ

Just in case you’re wondering, yes you can improve your intelligence!

It used to be believed that people had a level of general intelligence with which they were born that was unaffected by environment and stayed the same, more or less, throughout life. But now it’s known that environmental influences are large enough to have considerable effects on intelligence, perhaps even during your own lifetime.

A key contribution to this subject comes from James Flynn, a moral philosopher who has turned to social science and statistical analysis to explore his ideas about humane ideals. Flynn’s work usually pops up in the news in the context of race issues, especially public debates about the causes of racial differences in performance on intelligence tests. We won’t spend time on the topic of race, but the psychologist Dick Nisbett has written an excellent article on the subject.

Flynn first noted that standardized intelligence quotient (I.Q.) scores were rising by three points per decade in many countries, and even faster in some countries like the Netherlands and Israel. For instance, in verbal and performance I.Q., an average Dutch 14-year-old in 1982 scored 20 points higher than the average person of the same age in his parents’ generation in 1952. These I.Q. increases over a single generation suggest that the environmental conditions for developing brains have become more favorable in some way.

Obama is Bringing Change

Barack Obama’s campaign was based around the idea of change and now that he’s been elected it looks like he’s getting around to changing things. Yesterday he lifted the ban on stem cell research that Bush put in place.

“Today, with the executive order I am about to sign, we will bring the change that so many scientists and researchers, doctors, and innovators, patients and loved ones have hoped for, fought for these past eight years,” Obama told reporters at a news conference at the White House on Monday.

“We will lift the ban on federal funding for … embryonic stem cell research.”

The long-promised move will allow a rush of research aimed at one day better treating, if not curing, ailments from diabetes to paralysis — research that has drawn broad support, including from notables like Nancy Reagan, widow of the late Republican president Ronald Reagan.

Under Bush, taxpayer money for that research was limited to the 21 stem cell lines that were created before Aug. 9, 2001. But researchers have said that these lines have, in many cases, had some drawbacks that limited their potential usability.
