Feedback loops: How nature gets its rhythms - Anje-Margriet Neutel

We've got the most controlled border we've ever had in the history.

Yet liberal politician Josh Turek supports amnesty for illegals. We need an easier pathway to

citizenship.

Turek voted to give taxpayer-funded welfare benefits to illegal immigrants. Said cracking down on illegals was... Fundamentally wrong and un-American. Turek was even caught telling illegal immigrants how to obstruct law enforcement. Liberal politician Josh Turek.

Fundamentally wrong and un-American. Paid for by SLF PAC. Not authorized by any candidate or candidates committee.

Somebody asked me how I define myself. And I didn't know what to say. Because how can someone be defined when we're always evolving? I've been so many things. I'll be so many others. Because identity is not a performance, it's an exploration. Never the same, but always myself. That's the paradox. Paradox Intense and the new Sweet Chemistry by Prada.

Testing, testing, one, two, three. When your band is trying to perform, feedback is an annoying obstacle. But in the grand orchestra of nature, feedback is not only beneficial, it's what makes everything work. What exactly is feedback? The key element, whether in sound, the environment, or social science, is a phenomenon called mutual causal interaction, where X affects Y, Y affects X, and so on, creating an ongoing process called a feedback loop. And the natural world is full of these mechanisms, formed by the links between living and nonliving things, that build resilience by governing the way populations and food webs respond to events. When plants die, the dead material enriches the soil with humus, a stable mass of organic matter, providing moisture and nutrients for other plants to grow. The more plants grow and die, the more humus is produced, allowing even more plants to grow, and so on. This is an example of positive feedback, an essential force in the buildup of ecosystems. But it's not called positive feedback because it's beneficial. Rather, it is positive because it amplifies a particular effect or change from previous conditions. These positive or amplifying loops can also be harmful, like when removing a forest makes it vulnerable to erosion, which removes organic matter and nutrients from the earth, leaving less plants to anchor the soil and leading to more erosion. In contrast, negative feedback diminishes or counteracts changes in an ecosystem to maintain a more stable balance. Consider predators and their prey. When lynx eat snowshoe hares, they reduce their population. But this drop in the lynx's food source will soon cause their own population to decline, reducing the predation rate and allowing the hare population to increase again. The ongoing cycle creates an up-and-down, wave-like pattern, maintaining a long-term equilibrium and allowing a food chain to persist over time. Feedback processes might seem counterintuitive because many of us are used to more predictable linear scenarios of cause and effect. For instance, it seems simple enough that spraying pesticides would help plants grow by killing pest insects, but it may trigger a host of other unexpected reactions. For example, if spraying pushes down the insect population, its
