Overpopulation is not only the fact that there will be more people on the earth, behind that word lies is a huge consequence of earth not being able to produce enough resources. Because by increasing number of people on the earth we will still have the same amount of resources since it is a fixed factor that can go only down (example: fossil oil) Final consequence can be population collapse. This problem is more evident in developing countries because they do not have access to good “updated” education that will teach them how to conserve resources. Since they are also suffering economically they do not have access to birth controls. Most of them work in agriculture and have huge families because they think that one more mouth is acceptable to feed because two more hand swill be helping with the labor. It is approximated that on the earth are 6,896,700,000 people at this moment. And that every second ten people die while another thirty are born. Which means that every second we have 20 people more than second ago. In my opinion, the problem of overpopulation is still underestimate (and that is exactly why we are facing the problem) and majority of people do not believe that it is happening (same scenario happened with the problem of global warming – it was predicted many years ago but got significant attention recently). So I think that we should use science and technology in order to stress the importance of this problem on a global level. Scientists from different fields (Computer scientists, Sociologists...) can produce a great models of overpopulation that will be able to present their horrible consequence as well. And noways technology can contribute by handling those models (complex models with huge number of arguments).

Renewable energy is in my opinion very important and serious issue. At this moment, 85% of energy that we use is coming from fossil fuels that are fixed factor on earth and wont last forever. We can be free and say that nowadays world literally works and is dependent of fossil fuels. It is also well known that use of fossil fuels as another consequence will have creation of serious pollution. This is a great example where science and technology work together in order to produce something better, something called renewable energy sources. In my opinion green energy is consider as a serious problem and is getting significant attention. This problem will be solved when price of energy that is produced by renewable technology reach the price of energy that is produced by non renewable energy. This is a great challenge for science.

Clean water is a huge problem for some places at this moment. And the number of those places is getting bigger as time is passing. It is very scary and terrifying to know that ancient Romans had better water quality than a half of our population now. And that half of the world's hospitalization is caused by water diseases which results in 3,575 million deaths. This problem is in my opinion not getting the significant amount of attention because the people who control money are not affected with this issues at all. However, in my opinion this is a great task for scientists to produce technology capable of handling this problem. It is very sad to know that water covers 70.9% of the Earth's surface but some people are still having troubles to have it. By making technology that is very efficient in taking water out of air (and for that use renewable energy source like sun) we would help to many people. Another goal would be efficient and reliable transforming of see water to drinking and usable water should be another step closer to solving this problem.

I think that by fixing one problem we are creating another because in my opinion other reason why we are facing a problem like overpopulation is because some time ago we improved our medication treatment (which use to be issue before). By doing that we lover child mortality and increased life expectant. With overpopulation we will increase pollution...

Second question.
