Those who work at home may find that the solitude can be a double-edged sword. It is, of course, easier to (26) when you're in your own home with no co-workers coming by your desk to chat at random times. But while this solitude can feel blissful at times, when we have no mandate for social interaction during the workday—when we don't automatically run across people outside of those we live with—we can become lonely before we realize it.

Social media can feel like a lifeline to others, but this type of (27) can sometimes feel isolating as well, as these interactions can feel less personal than face-to-face encounters and conversations. (28) we may not need to resort to painting a face on a volleyball and talking to it, the feelings of isolation can sneak up and we can feel (29) alone than we expect. And given the research on loneliness, this doesn't always feel good. Social isolation was a factor mentioned in the UN study (30) was related to increased stress of home-based workers.

Who talk more men or women? Most people believe that women talk more. However, linguist Deborah Tannen, who has studied the communication style of men and women, says that this is a stereotype. According to Tannen, women are more verbal - talk more in private situations, where they use conversation as the “glue” to hold relationships together. But, she says, men talk more in public situations, where they use conversation to exchange information and gain status. Tannen points out that we can see these differences even in children. Little girls often play with one "best friend", their play includes a lot of conversation. Little boys often play games in groups; their play usually involves more doing than talking. In school, girls are often better at verbal skills, boys are often better at mathematics.

A recent study at Emory University helps to shed light on the roots of this difference. Researchers studied conversations between children aged 3-6 and their parents. They found evidence that parents talk very differently to their sons than they do to their daughters. The startling conclusion was that parents use more language with their girls. Specifically, when parents talk with their daughters, they use more descriptive language and more details. There is also far more talk about emotions, especially with daughters than with sons.

Scientists believe they now have scientific evidence to prove that ecosystems work better when there is a greater variety of species within them. This biodiversity is being lost destroying natural mechanisms that could repair the damage caused by man.

Findings show that losing plants and animals is not only reducing our quality of life but actually endangering our very existence. We cut down rich rainforests and replace them with one species plantations, such as pine and eucalyptus. We plough up meadows rich in different grasses and herbs and replace them with one grass, for instance rye or wheat.

When a natural ecosystem is simplified the basic processes in the ecosystem are altered and even damaged. Without their biodiversity, they are not able to serve as the natural cleaners of our planet. No longer are they able to absorb the carbon dioxide that is being produced in excess. The result is global warming, caused by the increase in the 'greenhouse effect', and ultimately, or even sooner, there will be a change in the world's climate.
