People have developed many communication tools to live together and build a strong societyies.

With the development of the internet in the last decade, social media has begun to take the place of other communication tools due to its easy use and the benefits it provides.

Social media is a new virtual media thattechnology that allows people canto explainress themselfves and stay connected with other peoples.

I've never heard the phrase "virtual media" before; I guess those words just don't tend to be used together.
"To explain oneself" - usually when you did something wrong and you're asked to say why you did it, what you were thinking, etc.
"To express oneself" - to share perspectives, thoughts, feelings, etc.

Also, people can follow people with common interests and have the chance to communicate with them.

More concise: "Also, people can follow and communicate with those who share their interests."

This also applies into the field of education.

Thanks to social media, peopleusers can follow successful people in their field and receive various educatiolearn from them.

You typically receive education in a school or program; it's a more formal thing.
I switched the first "people" to "users" to avoid redundancy.

Another significant benefit of social media is that users of the social media can follow the latest happenings all over the world easily.

Or: "users can easily keep up with current events."
Never put "a" or "the" in front of "social media." However, you can say "a/the social media PLATFORM."

We can learn about significant events that have taken place directly from the people related with the event and follow the worlimpacted.

More concise/more natural.

With the common use of the Internet, people's access to social media has become easier.

More natural: "As more and more people gain access to the internet, it becomes easier to use social media."

However, this convenience has broughtled to/strengthened the idea that people can do whatever they want on social media.

What you wrote is grammatically correct, but "brought the idea" sounds odd/unnatural to my ear.

According to studies, especially young people are most affected by cyberbullying, and this situatiowhich can even bringslead t suicides.

However, people register with manyAdditionally, people share a lot of personal information on social media sites.

"However" implies contrast. You're adding information here, not contradicting the previous sentence.

"On social media sites" is technically redundant.

This leads to theft of personal data and invasion of privacy in case of any security breach.

Security breach is different...like when you break into a facility or particular system, not just individual identity theft.

The fact that it is easy to communicate on social media causes fraud to increase, and many people who do not use the internet well are harmed.

Except forAmidst all these negative aspects, one of the most important is the harmful effects of social media on health.

The long hour use of the internet andExcessive use of social media platforms brings with itcan lead to internet addiction.

The tendency to addiction, especially among young people, causes greatincreases the risk of psychological diseaseorders.

Psychological disorders, mental disorders, mental illnesses, psychiatric illnesses...the word "disease" has fallen out of use in this context.

Otherwise, especially young people may be exposed toin particular may experience irreversible negative effects due to social media.
