What comes around goes around

In California, San Fransisco is going even greener by using the methane gas from the large landfill to power garbage trucks. By drilling a hole into the mountain of decomposing waste, much of the trapped methane will be used to fuel trucks and poison the Earth less.
The landfill will eventually be used as a park or something of the sort in the future when humans can find an efficient way to dispose of their garbage after 80% of it is recycled. Methane is natural gas yes but if it isn't dispersed into the atmosphere one way or another and is trapped underground, the methane itself will become a liquid poison that will not allow much of anything to grow on top of it. The poison would then take several hundreds or thousands of years to reach the core where the poison will burn off or if there is enough pressure it could form crude oil. Though that is just a possibility. San Fransisco recycles much of what they use. San Fransisco is the capital of recycling in the U.S. So far no other city can match the amount that San Fransisco recycles.
We should care about using methane as the main alternative to replace oil for garbage companies, ranches, and other places where methane can be produced. Buy reducing consumption, the supply is increased and demand decreases causing oil to be sold much cheaper than before. Although methane is a natural alternative, the liquid form of the gas can't be used as of yet for fuel for cars.
In order to make the most of the methane, 350 trucks in southern California is run by the one landfill alone. With the methane being mined, 30,000 tons of Carbon Dioxide is kept out of the atmosphere and the company saves 15 million every year by mining the methane.
