Many scholars predict that at least 40% of the world's languages will be dead by the year 2100. You may say "No language exists forever. Just as plants and animals have appeared and disappeared over the millennia, languages evolve, grow, and spread, and eventually dwindle and die". But let's take a look at this problem and try to understand.
Today people on the Earth speak about 7 thousand languages but every 2 weeks one language desappears.
In fact scholars argue that all languages have mixed and influenced each other. However, today the whole world is turning into a unified information space.  The globolisation has devastating consequences. And in the future many languages may endangere to vanish. It is very important to retain identify of each language because when the humanity loses each language it loses a part of world culture. Each language is unique. For example the language of Eskimos has about 40 names of snow.
English is one of the most spoken languages in the world. It has become a world language during last few centuries and now over 1300 million people speak it. Many languages: German, Franch, Spanish and Russian experience the influence of English.
We face two alternative scenarios for the future. In one, the world becomes increasingly homogenized as minority cultures and their languages are swept away in the oncoming tide of standardization. The accumulated knowledge of millennia disappears, leaving the world a poorer place with the extinct culture. In the other scenario, minor languages continue to exist alongside larger ones. Which scenario comes to pass depends to a large extent on our actions now.

It’s hard to imagine our lives without Internet nowadays. It has become an important part of every person’s life. It seems that Internet has created a whole new history. It has drastically changed everything around. Computers were also an important invention, but Internet is better than any other type of information. Besides, it’s not only used for information, but also for global communication. In spite of all the good sides that Internet has, there are some drawbacks. As well as on TV, there is a lot of violence and cruelty online. Nevertheless, every day millions of people turn on their computers and start surfing the worldwide net, because it’s the easiest and quickest way to stay informed.
