How to develop an essay on the importance of Internet

Let's imagine you have an essay tase as: Your class has had a discussion about the importance of the Internet in our lives. 

Brainstorm the essay title:
Reasons why the Internet has become so important:
- the opportunity it offers to buy and sell online,
- the ease with which we can keep in contact with friends or relations
- its use as a study tool. 
- Social media allows me to stay in contact with family members all over the country. 
- You can shop around, read reviews and get good bargains on the web. 
- The Internet offers me an enormous library to help with my studies.

By using the same ideas I might develop my essay like this:

Internet plays a strategic role in our life and it’s so impossible to live without it that some get sick if they are not allowed to use their electronic devices as recent studies have revealed. It offers a wide range of opportunities as buying and selling products, get good bargains, keeping in touch with different people on various parts of our planet, applying for job, studying, booking a holiday, a ticket to a concert or another kind of event, sharing pictures and videos, having access to news and all sorts of information, listening all kinds of music and watching films and programs appealing to to all tastes. Nevertheless, Internet despite all advantages it gives rise to, has some drawbacks which it’s essential to reflect upon, derived from its intensive use as memory lapses, difficulty to concentrate, an impact on thinking and reasoning skills, a sort of dangerous addiction. But the most striking effect is a sort of isolation individuals might feel despite all contacts people might be proud of, with a severe influence on social skills. To draw a conclusion Internet is important but it shouldn’t overrule our lives.
