To begin with, I agree with the statement that life in 2020 will be better. I believe in that because of the following reasons that I will explain in the coming paragraphs.
First of all, I think that technology plays a very important role in the life of most people who live in developed countries. In my opinion by 2020 technology will have become more advanced and I’m sure that new gadgets that will make our everyday activities much easier will have been invented. For example, a method of texting by thinking may be invented. In addition to that, I think that transport will have developed more by 2020. There might be a new way of transportation invented or the ones that already exist, for example air transport, might be much more advanced that we might be able to travel from Belgrade to New Zealand in just a few hours.
On the other hand, there might be a really great oil and global crisis by 2020, which will result in bad economy for most countries and will lead to widespread social restlessness. This can lead to various riots, revolt and even third World War. If various riots and wars break out because of the shortage of supplies, then poverty and hunger may strike even harder and spread on all parts of the world.
In the end, life in 2020 will be better if people learn to save energy and take better care of planet Earth and nature that is surrounding them.
