Primarily a mosquito borne disease, the Zika virus is most impactful in warmer seasons when illness can be transmitted by insects carrying the virus from one person to another. Maintaining a keen awareness for the transmission and treatment of Zika virus infection is an imperative for healthcare practitioners.
Coal is the most plentiful nonrenewable resource in the world and is used to create more than half of the electricity used in the U.S. Coal is made when plant material has been compressed in bogs for millions of years.
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun.Th e coal we use today took millions of years to form. We canât make more in a short time.Th at is why coal is called nonrenewable. 300 million years ago Before the dinosaurs, many giant plants died in swamps. 100 million years ago Over millions of years, the plants were buried under water and dirt.Heat and pressure turned the dead plants into coal.n fact, it is burned in power plants to produce more than half of the electricity we use. A stove uses about half a ton of coal a year. A water heater uses about two tons of coal a year. And a refrigerator, thatâs another half-ton a year.
