I need an essay about world global issues please help me !!!!!!!

Global problems are those which affect not only one individual but the whole mankind. They can’t be solved in one day and require organized efforts from the world community. If people leave these problems unsettled, it may lead to serious consequences in the future. It will affect all humanity and environment. All in all, global problems are the following: environmental pollution, climate change, resource issues, overpopulation, nuclear weapons and some others. Speaking about pollution, I’d like to mention the Chernobyl disaster, which was the result of reckless economic activities. At the moment, many forests and rivers are also endangered due to careless attitude. 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. Many environmental and social problems are the result of overpopulation. Nuclear weapon is one of the most terrifying global problems. The use of such weapon is against any international law. Apart from nuclear there is also chemical weapon and biological. Another threatening problem nowadays is terrorism. It endangers life of every person on the earth.
