Negative Feedback Loop

Negative feedback is not always a bad thing. This does mean that we as humans have done something wrong to harm the environment and organisms in it. However, it lets us see what we did wrong and how we can fix those problems. For example, water pollution is something that happens everywhere by humans. People will dump poisons and other harmful things in rivers and lakes. We see the effect of this on the animals in those environment. Those animals will either die off or they will infect humans who eat those animals. As humans we will help stop polluting the water systems so the whole environment can enjoy clean water.
