All in all, global problems are the following: environmental pollution, climate change, resource issues, overpopulation, nuclear weapons and some others

In the 21st century our world faces one of the most urgent problems – the climate change. The earth is warming up. As a result some species and their habitats suffer. Recent years have shown increasing temperatures in some regions and extreme weather conditions, including hurricanes, earthquakes, and tsunamis. The shortage of resources is another pressing issue. Natural resources are limited and we can’t use them carelessly. The increasing number of factories is the root of this problem. The world’s population will soon reach an intolerable level and this will lead to the shortage of resources as well. To avoid the catastrophe this growth must be stopped.
