I work on such programs to automate agricultural, mining and construction processes where human health can take a hit due to exposure of coal dust, fly ash and carcinogenic chemicals sprayed. 

Such excessive mass production are the results of capitalism and increasing global population, world hunger and food needs.

One such program, we worked on is SEE AND SPRAY of John Deere. Good side is, it reduces 80% of chemicals used in agriculture. We put cameras everywhere with software to make autonomous systems, self decision making.

The software analyses soil nutrients and weeds in the continuous frames of picture taken by camera using image processing algorithms and sprays particular chemical like phosphorus/ magnesium or weedicide on that particular node, instead of showering chemicals all over.

But you may ask why use so much chemicals on it in first place. We are in the reality, to multiply everything. We can comfort ourself that we are doing it little efficient than before.
