WHAT IS PREVENTING US FROM STOPPING GLOBAL WARMING?
 AND HOW CAN WE PUT AN END TO IT:

• government doesn't want to invest too much money into the process of stopping global warming
• the people say that the price may be high but it is not infinite
•  There are many potential solutions to serious problems that we do not implement, or that we implement only partially, because the costs associated with them are greater than the benefits.
• biofuel requirements were supposed to help reduce carbon emissions? In fact, the artificially inflated demand for ethanol and for the corn to manufacture it wound up driving up food prices (which pushed about 30 million poor people into the ranks of the malnourished). It ate up more arable land, which led to the destruction of rain forests and created a situation that will result in more CO2 emissions over the next 100 years.
•  If we panic and make the wrong choices in response to global warming, we risk leaving the world's most vulnerable people even worse off
• Replace a regular incandescent light bulb with a compact fluorescent light bulb (cfl)
  CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon dioxide a year.
• Move your thermostat down 2° in winter and up 2° in summer
  Almost half of the energy we use in our homes goes to heating and cooling. You could save about 2,000 pounds of carbon dioxide a year with this simple adjustment.
• Move your fridge and freezer
  Placing them next to the cooker or boiler consumes much more energy than if they were standing on their own. For example, if you put them in a hot cellar room where the room temperature is 30-35ºC, energy use is almost double and causes an extra 160kg of CO2 emissions for fridges per year and 320kg for freezers.
• Take a shower instead of a bath
  A shower takes up to four times less energy than a bath. To maximize the energy saving, avoid power showers and use low-flow showerheads, which are cheap and provide the same comfort.
• Reuse your shopping bagWhen shopping, it saves energy and waste to use a reusable bag instead of accepting a disposable one in each shop. Waste not only discharges CO2 and methane into the atmosphere, it can also pollute the air, groundwater and soil.
