From the point of countries, politicians will perceive the ongoing situation as a wake-up call with regard to lower birth rates, more demands on houses, and more energy consumption. Firstly, more single households mean more single persons, and the population will shrink in the wake of falling number of married couples. Secondly, more houses are required to fulfill the need of individuals, which cause cities even more densely populated. London is a famous example; the number of houses has been stimulated by 48% over the past five years, and 80% of them are for singles. Finally, the consumption of electricity and gas will soar when more people choose to live on their own, and it will further pose a threat to our livelihood.
The main reason to start kids off with foreign languages early is that this increases the likelihood they will achieve fluency in adulthood. That is to say that they will have far more years to perfect their skills and it will seem perfectly normal to speak bilingually. For example, in countries such as Holland and Norway where English is taught from a very young age, more than 95% of adults speak it at an advanced level. Learning a second language also helps to improve overall cognitive abilities. In other words it benefits the overall development of a child’s brain. A recent survey by Cambridge University found that children who studied a new language before the age of 5 were significantly more likely to score higher in Mathematics and Science.
