Week 7- Thinking Globally

Global Warming
​Steps Taken to Reduce Global Warming in My School

          Is global warming that we should worry about or is it something else we should pay attention to? For me, whether global warming is true or not, I think it is better to be safe.
 
       But first, what is global warming? According to NASA Earth Observatory, it is a rapid increase of average earth's surface temperature due to greenhouse gases that are being released to the atmosphere by human activities. Our science teacher said that these gases destroyed the ozone layer. The ozone layer is the one that filters the heat of the sun. According to Wikipedia, average temperature rose around 0.6 to 0.9 degrees Celsius from 1906 to 2005 and that rate is almost doubled for the last 50 years.

       Reducing emissions of greenhouses gases is the major way to reduce global warming. For example, planting stuff with leaves or trees because plants will absorb the major greenhouse gas - the carbon dioxide! Reducing the burning of fossil fuels, and reducing harmful waste to nature. These are the common actions we can take to reduce greenhouse emissions, but the easiest thing to do is planting trees.

             My classmates and I joined an event a few years ago, aiming to reduce global warming. I don’t remember the name of the event. But I remember that we planted small plants that I know will grow and absorb a lot of greenhouse gases. And in my little ways, I also apply the 3R principle - reduce,  reuse, recycle.
