Yes natural disasters are man made Most natural disasters today, like floods and landslides have been caused because of human interference. For ego. The Attractant floods in India were caused because of over construction of buildings, which caused the unstable hilly land to fall like Lego blocks. Similarly, landslides today are caused because people cut down trees which loosens the soil. Global warming, a slow onset disaster, is also caused mainly because of human interference with nature. It is always the humans who have to play with nature in every possible ways be it from having a dream of full development till destroying the nature .
