Systems Thinking

As the Earth warms, increased evaporation produces more clouds. Clouds increase albedo, reflecting more light away from the Earth. The temperature falls. Rates of evaporation fall.

A organization posts an advertisement with a very "click-baity" title and image on a social media platform. The title and image draw in people to click on the ad. As the ad receives more views, the algorithm shows the ad to more people.

As the Earth warms, upper layers of permafrost melt, producing waterlogged soil above frozen ground. Methane gas is released into the environment. The greenhouse effect is enhanced. The Earth warms, melting more permafrost.

As the Earth warms, ice cover melts, exposing soil or water. Albedo decreases. More energy is absorbed by the Earth’s surface. Global temperature rises. More ice melts.

In some developing countries poverty causes illness and contributes to poor standards of education. In the absence of knowledge of family planning methods and hygiene, this contributes to population growth and illness, adding further to the causes of poverty; “a vicious circle of poverty.”

In a negative feedback loop, each action creates a consequence that _____________________ the other action.

In a positive feedback loop, each action creates a consequence that _____________________ the other action.

Erosion is an example of

Shivering in response to being cold is an example of

Some organisms have internal feedback systems, physiological changes occurring prevent breeding when population densities are high and promote breeding when population densities are low.
