Drones have also been successfully used by environmentalists to help keep track of the changes in the environment. Tushvel aerials liaising with the Brazilian state have also used drones to help watch and keep safe the Amazon’s indigenous forest which is in the Amazon forest. Another example is of how the University of Toronto as well as MIT has come up with a project that uses drones as well as high tech sensing technology to look in to and check any form of cyanobacteria in lakes and rivers ("Humanitarian Uses Of Drones And Satellite Imagery Analysis: The Promises And Perils" 2015). This is because the bacteria are very harmful to animals as well as human beings who are dependent on the river for drinking water.
When it comes to its civilian use drones have been used by human beings to check storm patterns. A good example is NASA. Not long ago NASA spent close to about $ 30- million on drones to check storms (Sandbrook 2015). Even though drones are small, this reason has not stopped some government and states to use the drones in surveying their lands. States as well as military surveillance have mostly used drones in such a way. One benefit of using drones to survey land is because it gives one a 3-D
