'Digital life' -The 21st century has begun. What changes this new century will bring?

During every era human being have discovered and invented new things. Human being have curiosity about world and human origination, as well as invented new things for humans comfort. In the 19th century humanity discovered the many things like car, airplane and so many faster way of transportation. In 20th century, innovation in technology like the computer, digital boosted as well as development in various field like medicine and science took place. As I believe that 21st century will be ahead among those development and give beneficial changes in our life.

The first change will bring in Robot mechanism. Nowadays, people are educated and want a carrier in mentally work rather than physical work and want to earn more money. Day by days it is very difficult to get people for regular work like cooking, cleaning and other physical hard work. So scientists have the challenge to find an artificial machine which is helpful to all kinds of work. Robot concept was introduced in 20th century but it will be carry out spectacularly in 21st century. Robot will help people in house, office and field. It will not only work physically but also it will use memory and take proper decision in difficult situation. Some time robot will help us in our mental work like calculation and solving difficult mathematical problem.

The second change, I am expecting is a adventure trip on another planet. Scientists are working very hard to find faster and cheaper way to another planet. Now only astronauts can possible to go to another planet but soon people will open their resorts and motels there. Now we like to visit Australia or Us or other places in the world but soon we should be expecting to go to another planet.

The third change, I am considering is the environment. The 20th century was faced a critical problem to the environment. All countries tried to control on various pollution and introduced people about global warming. The 21st century will find the solution on it. As technology is developed in all areas, it will be developed for improvement on environment.

In conclusion, the 21st century will bring many changes. It will be a beautiful world which will find not only comfort for human being, but also consider development of other creature on the earth. This century will bring adventure, peace and comfort for all.

Hi Vaishali, I am so impressed with your diligent practice of English writing!

I notice here that you were using human to mean humanity. I am a human, but humanity is a word that refers to all humans together.

Example: It will be a beautiful world which will find not only comfort for every human, but also will find the truth of life.

above, you can see the correct ways to use human and humanity.

I like this sentence!!!----> This century will bring adventure, peace and comfort for all creature.

has & have
One thing has...
Two things have...

So...make it plural: beings
During every era human beings have discovered ...

Human beings have curiosity about ...
...which will find not only comfort for human beings, ...

As I believe that 21st century will be ...
The correct way to use 'as' is like this:
As an example of my personal beliefs, I'll state that I believe that the ...

No need for commas:
The third change I am considering involves the environment.
The second change I am expecting is...

Just like humans, use an s for robots:
Robots will help people in house, office and field.
but there is a mistake her, too:
Robots will help people in house at home, at the office, and in the field.

I think add details about how the environment will change in the 21th century could make your point stronger.

Thanks for suggestion.

Kevin I have question

'Robots will help people at home, at the office, and in the field.'

You used 'the' before office and field but why you didn't use 'the' before home

Good question, my friend! As usual, I'm impressed with your careful study.

All of these are correct:
Robots will benefit me at home.
Robots will benefit me at the office.
Robots will benefit me at work.
Robots will benefit me at school.
Robots will benefit me at the park.

Why do we use 'the' sometimes and not at other times? It is because of the way language has developed over the course of generations.

This is correct, but it sounds strange:
I can use robots at the home.

So, it is very hard to get used to the conventions of any language. For now, all you need to know is this:
Robots benefit me at home.
Robots benefit me at work.
Robots benefit me at the house.
Robots benefit me at the office.
Speak those aloud several times to program your brain with the conventions of English! :-)
