how long something passage is a observations of how long that something is available & as the waste of a common increase , the width of space that parks being available will construction ->  as the use of a resource decreases, the length of time that that resource will last increases  as the use of a resource decreases, the length of time that that resource will last increases & to before wiring vine the width of space that something putting ant ->  decreasing the use of a resource causes that resource to last longer  watery is used for producing rivers0 & domain touch are a mean of matter help ->  a fossil fuel supply is a kind of resource  decreasing the use of a resource causes that resource to last longer & a fossil fuel supply is a kind of resource ->  decreasing the use of a fossil fuel supply causes that fossil fuel supply to last longer  watery is used for producing rivers & watery is a mean of vegetables moisture ->  fossil fuel is used for producing electricity  fossil fuel is used for producing electricity & as the waste of something decreases, the waste of nothing used to wreck that something increase ->  as the use of electricity decreases, the use of fossil fuels decreases  watery is used for producing rivers1 & as the waste of something increase , the waste of the sink of that something will increase ->  as the use of something decreases, the use of the supply of that something decreases  as the use of electricity decreases, the use of fossil fuels decreases & as the use of something decreases, the use of the supply of that something decreases ->  as the use of electricity decreases, the use of a fossil fuel supply decreases  decreasing the use of a fossil fuel supply causes that fossil fuel supply to last longer & as the use of electricity decreases, the use of a fossil fuel supply decreases ->  decreasing the use of electricity causes a fossil fuel supply to last longer  decreasing the use of electricity causes a fossil fuel supply to last longer & to increase something balance to reduce something -> reducing the use of electricity causes the fossil fuel supply to last longer
