Global warming or climate change has literally and figuratively been a hot topic for a couple of decades now. Some researchers feel that our planet Earth is going through normal and natural evolution, as it has for its entire history. Other researchers feel that human beings are increasing the speed and size of global warming with non eco-friendly behaviors.
As the summer heats up and we witness volatile temperature swings throughout the years, scientists continue to do their best to try to unravel this mystery.
Greenhouse gases, such as methane and carbon dioxide, trap heat from the sun, thus causing a rise in the Earth's temperature. This type of gas and heating of the Earth is actually a normal process that helps to keep the temperatures on our planet livable, even at night when the sun goes down, by providing us enough heat to survive. Of course this heat helps our plants to grow as well. The trouble starts when these greenhouse gases become too much and the Earth becomes too hot. This can result in glaciers melting and thus water tables rising, along with other life-altering consequences.
Greenhouse gases can come from fossil fuels, such as oil and petroleum, being burned to create electricity for example. As the population around the world grows, so does our electricity use, and thus the creation of greenhouse gases. This is the argument of scientists who think that the melting of glaciers and the volatility of temperature changes is due in part to the overuse of resources by human beings.
Whether or not one believes that humans contribute to climate change by using more electric or driving more cars, it does not hurt anyone to decrease his or her use of resources. Whether or not it is proven that humans are increasing the rate of global warming, it does not hurt anyone to bicycle instead of drive twice a week, hang their clothes out to dry or plant one tree a year. Rather than get mired down in the debate, it may be a good time to simply create a more natural life for each other.
