There are many environmetal considerations made in constructing power lines:
Environmental science is the study of the effect of the physical, chemical and biological conditions of the environment and its affect on the organisms within it. Because animals live in just about every environment, they are also affected by any changes that may happen to their habitat. Animals are one of the largest parts of environmental science because they are the first things to show change when the environment is changing or disturbed, and may determine the cause of many environmental problems.
Accirding to the vast majority of the studies, the short answer is "No". A small number of studies show some indications of relationship. It is extremely difficult in science reports to say that you are sure 100% (not 99,99%) that "something" DOES NOT cause "something other".
the lines are meant to show symbols
The Mr. Science Show was created in 1991.
The Mr. Science Show ended in 1995.
The duration of The Mr. Science Show is 3600.0 seconds.
The lines show where a phase changes happens to a substance -
you can show movement with lines.
Maps can show elevation with contour lines
Contour lines show levels of elevation, where there are hills and valleys on a map
show diagram of poulan chain fuel lines
I would suggest that you do create a wind turbine, and then show how the kinetic energy is turned to energy that can be used. You can include the science factors of this and then the global affects of not using renewable sources. hope that's helped!
