The negative effect humans have on the stability of the environment is mostly directly linked to an increase in

Explanation:

Machinery as an energy unit for agricultural work produces a negative impact on the environment on soils, waters and the atmosphere. ... In the exploitation process it exerts impacts such as: soil degradation, water pollution and pollution of the atmosphere.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
