Can Wolves Change Rivers?

Ecology (from Greek: οἶκος, "house") is the scientific study of interactions among organisms and their environment, such as the wolves-in-yellowstone-national-parkinteractions organisms have with each other and with their abiotic environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), number (population) of organisms, as well as competition between them within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.

To put this more simply, did you know that wolves can change rivers? The video below makes the case for just that very thing.

Update your Light bulbs

CFLThis one is a no-brainer: Swap your old incandescent bulbs for compact fluorescents (CFLs). Each bulb may cost a little more (between $2 and $7), but a compact fluorescent will pay for itself in mere months and prevent 450 pounds of power-plant emissions over the bulb's lifetime.

If every U.S. household replaced just one incandescent bulb with a compact fluorescent light bulb, the amount of energy saved could light 2.5 million homes for a year.

To help choose the bulb with the right light output for your purposes, visit the chart on EnergyStar . If you need further convincing, Popular Mechanics has recently done a lab test comparing CFLs and incandescents. You'll be surprised at the findings.
