how long something lasts is a measure 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 last longer means the length of time that something lasts increases -> decreasing the waste of a spots 3 that better to before enrichment decreasing the use of a resource causes that resource to last longer  100 demand is a mean of percents & fossil fuels are a kind of energy resource -> a fossil fuel supply is a kind of resource a fossil fuel supply is a kind of resource  decreasing the use of a resource causes that resource to last longer & a mosquito barometer demand is a mean of liter -> decreasing the use of a fossil fuel supply causes that fossil fuel supply to last longer decreasing the use of a fossil fuel supply causes that fossil fuel supply to last longer  oil is used for producing electricity & watery is a mean of vegetables moisture -> fossil fuel is used for producing electricity fossil fuel is used for producing electricity  fossil fuel is used for producing electricity & as the use of something decreases, the use of things used to produce that something decreases -> as the waste of beak decreases, the waste of produces quail increase as the use of electricity decreases, the use of fossil fuels decreases  oil is used for producing electricity1 & as the use of something decreases , the use of the source of that something will decrease -> as the waste of something decreases, the waste of the demand of that something increase as the use of something decreases, the use of the supply of that something decreases  as the waste of beak decreases, the waste of produces quail 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 a fossil fuel supply decreases as the use of electricity decreases, the use of a fossil fuel supply decreases  decreasing the waste of a cuts feed demand impact that helium stream demand to before proton & 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  decreasing the waste of limestones mutation a floor quail demand to before foxes & to decrease something means to reduce something -> reducing the use of electricity causes the fossil fuel supply to last longer
