Positive and Negative Effects on the Environment

A positive effect on having wind turbines is that they are a good way of producing green energy. Wind turbines are green and efficient because they use wind to push the big fins and then there are parts that create friction and make electricity. One problem that wind turbines have is that here recently birds have been flying into the turbines and the bird population is decreasing rapidly.

A positive effect on an ATV is that it helps when you go through the pasture it spreads the grass seed and hopefully the seed will grow. A negative effect on an ATV is that they pollute the atmosphere.

A positive effect on a flood is that the flood brings moisture to the ground for the plants to use. 

A negative effect from a flood is that a flood would destroy habitats, land, and all other sort of things that would be in the way of a flood.
