A natural gas flame

A gas that is made up mostly of methane and found near other fossil fuels, like coal. Methanogenic processes occurring in landfills and marshes also produce natural gas. Like petroleum, natural gas must first be processed before we can use it as a fuel. It is important to remove most of the other components of natural gas until it is almost purely methane. When combusted, natural gas produces only about half the greenhouse gas emissions as coal does, making it a popular fossil fuel in our increasingly carbon-conscious society.

Technology is sci-fi, its the dream that takes us places, the cars that take us where no man can walk solely to by his legs. But it is also the dream that has the potential to turn to disaster.I think that we created technology to help ourselves reach and connect with more shortcuts that lead promising results from within our problems, from within our reach. Rely on it, I would say yes, but to overuse it and apply it to every part of our lives can create confusion, chaos, cyber bulling, or create humans lacking the ability to hold a conversation without the use of emojis or erasing thoughts before posting.I think that technology has been useful, however it matters to how we use it and what situations we use it for. For example, if it is a task such as remembering, we can use technology to remind us, however, what about our brain which was used especially for this function? Are we just going to abandon our minds for technology to remind us children doing chores? In turn by introducing technology at an early age to a child, some children miss out on the opportunity to learn how to socialize in person with others and to learn communicating skills. When technology replaces how a child develops, it can change a child’s personality, delay their speech, teach the child bad habits regarding the use of technology, or have them become addicted to electronics very quickly leading to an increase in myopia (nearsightedness).
1 Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.
2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.
Climate change means no airport expansion – at Heathrow or anywhere
George Monbiot3 Home heating is next. Poorly insulated housing requires large quantities of energy to heat. If you have properly insulated the loft and filled the cavity wall, the most important action you can take is to draught-proof the house, something you can do yourself. Those with solid brick or stone walls will also benefit from adding insulation, but the financial benefits are unlikely to cover the cost of doing the work, over time.
