EXPLAIN How might you use engineering, either by designing a device or process, to help reduce the impact of human activity on a local species?

A microwave absorbing device can be created to absorb the microwaves in the air from the communication signal plant or lines.

Cell phones or towers of cell communication, or towers can emit a frequency of 900 to 1800 MHz microwaves which are responsible for negatively affecting the health of birds.This have been proved that it can cause thinning of the skulls of the chicks and thinning of their egg shells which can reduce the population of local bird species. Thus the development of microwave absorbing device can help in reducing the negative influence of microwaves on bird species population.
