Why the body temperature decreases when you do not eat food?
Does recycling paper and glass use more energy than it saves?
Paper No, recycling paper uses less energy (between 40% and 64% less) than if the paper was made from unrecycled wood pulp. Some calculations suggest that recycling one ton of newspaper saves enough electricity to heat and air-condition the average American house for 6 months. Glass No, recycling glass uses about 40% less energy than making virgin glass from sand, lime and soda, as the furnaces don't need so much energy. Recycling two glass bottles saves enough energy to boil 5 cups of coffee.
