2. Talk about cause, effect of a certain type of pollution as well as solutions to this problem (water pollution)
Water pollution can be defined as the contamination of a stream, river, lake, ocean or any other stretch of water, depleting water quality and making it toxic for the environment and humans. It can occur in many ways: industrial activities like dumping waste which drains in the fresh water make it polluted; or agriculture activities like using pesticides, herbicides....; and the garbage that we throw everyday. And it effects seriouslly. First, water pollution truly harms biodiversity and aquatic ecosystems, makes the creature sick or even die. Next, it has very negative effects on human health because it is the cause of many diseasessuch as diarrhea, cholera, skin infections.... or dehydration because of lacking of fresh water. Besides, it destroys environmental landscape,..etc. But we can reduce water pollution in many effective ways like reducing the amount of water we use, having green agriculture or throwing rubbish into right places..... Water pollution is a serious problem, but we can solve it if we try hard!

Communication in the Present:
The telegraph was the first major milestone in the development of communication technology because it led to many of the things we use today and its similar to techniques we use today. Expansion in this past technology has made it possible for many of the things we use today, such as telephones, radio, cable television, Internet, and mobile phones.
It was not long after the telegraph became a success before the next progression in technology came along, the telephone. The telephone was used to transmit speech electronically, which was a success. Unfortunately, it failed because under-water cables did not have a strong enough signal.
Another major advancement in technology that most of America has benefited from is the cell phone. Cell phones have evolved immensely since 1983, both in design and function. This envolvement brought a whole new meaning to the term multitasking. Cell phones today can do any and everything from sending text messages, to emails, to uploading video and picture, and most importantly downloading applications for everything.
Modern day technology keeps communication constant; it allows people to express themselves with a click of a button.
Technology in the Future:
The future holds a lot of promise for auto voice translating and interpretting, which will remove any language barriers. The future progression in technology will change the dynamics of communication all across the world, in the classroom, the workplace and in the public sphere. It is unknow what the future may hold for the advancement communication technology, but it is not far-fetched to say that we may one day be able to send emails with our own thoughts or brainwaves where ever we are.

Have you ever asked yourself what ways of communication you will be using in the future?
I strongly believe there will be huge changes in the way we communicate.
Presently, we often meet face-to-face, send emails or chat online to work on our group projects.
But it’s possible that in the year 2030, we’ll be having video conferences with 3D images and Hololens Virtual Reality Glasses to interact with these people.
When we want to ask our friends to get some drinks, we often contact them by phone or social media.
However, in 20 years, super-smart phones, which can read your thoughts and automatically transfer them into text or voice messages, will be replacing those methods.
Besides, I guess telepathy will be especially popular then.
And I bet in 40 years, we will be able to understand what our pets are thinking with the help from some smart devices.
That will certainly be very amazing!!!
