I agree!  I was watching "Earth Without Humans" on History Channel, a theory of what would happen if humans dissappeared instantly from the planet, what would happen as the years progressed, it was preposterous! 
 
For example, after 3 years the Burj Tower in Taipei would be leaking rain water on all floors from broken windows produced by storms, and the building itself would crash to the ground in 50 years due to a 80-ton ball of steel it has on the upper floors falling due to rust erroding its steel cables holding it....  what difference does it make if humans exist or not, why would the steel cables rust any faster or the windows break from storms so fast?
