give reasons why remote sensing is essential for environmental management.?

Answer 1

The old question is "If a tree falls in the forest, and there's noone there to hear it, does it make a sound?"

It's the same with EM. If you don't have enough personnel to visit the environment regularly, remote sensing lets you keep tabs on what's shakin.

Answer 2

Remote sensing has the advantage of reponding to an event(s) for expediant transfer of data for analysis or engaging some corrective measure.

Answer 3

The remote sensing devices on my car are essential, the last one I had didn't have them and I kept bumping into walls backing up. No more dints on the back fender!!
