It can be transferred by temperature because it dissolves the oxygen and the presence of nitrates. It doesn't affect the insects or fish, but the excess levels on nitrates and water can create conditions that make insects, fish, and other plants survive. It can affect humans because nitrates cause change in molecules that help move oxygen in the body.
Phosphates generally come from fertilizer, erosion of phosphate-containing rocks. they are fertilizers, so they tend to strongly encourage growth, particularly of bacteria and algae. This can harm ecologies, particularly in water, and particularly where there isn't a very robust growth medium already, e.g. in cold or desert waters.<span>This impacts the environment and our health because we use tap water for cooking, bathing, brushing teeth, and etc. and these water by be contaminated because of all of this pollution going around</span>
