What human activity will lead to an increase in resources for the plants and the animals of the area shown

In the image, we can see two types of environmental contamination, the first image, for example, you can see direct contamination of the water (causing water pollution), which affects plants and animals living in it and also near it.

The second case is more indirect, this contamination affects air and clouds, is less intense in a specific area but can spread more.

A human activity that can lead to an increase in resources for the plants and animals is controlling this contamination, for example, there are companies that collect the chemical residues, and in this way, the factory does not throw them in the water, and there are a lot of other ways in which factories can control the contamination that they cause.

i believe it is b. what was the cause of the big bang
