Effects on the Environment By Faith

Number one riding ATV's over the land has a mainly negative effect on the environment by ruining habitats, or even hurting animals. However the ATV can make a trail and it is easier to make a habitat in the ground so you could say it has a positive and a negative effect on the environment.

Wind Farms 

                      Wind farms are commonly credited to be so helpful to the environment because they use energy with wind however they take up a lot of space so there is less room for habitats for animals. Also according to http://www.ucsusa.org many bats and birds have had collisions with the wind turbines. However by using wind for energy waste isn't sent into the atmosphere so it isn't ruining the ozone layer so I guess you could say that it has more of a negative effect in my opinion.

Floods
             Floods are mostly concerned to be negative but if that village had population of say wolfs had a illness that could spread to humans it is a good thing if they died and along dies the illness. Still not many floods seem to be like that so they still happen to have a major negative effect on the atmosphere.
