I believe that cars should not be banned- instead biofuel and hybrid or even electric cars should be used. All other cars that use gasoline- especially diesal- should be banned. They should have been banned a long time ago.
The number of cars are increasing, which means more pollution.
More people should walk and ride bikes. If work is only a few blocks away or even a 45 minute walk- it is worth getting the execise and cutting down the amount of pollution. People have grown lazy over hte years- and have caused the environment to become more damaged- by driving to the store or nearby destinations that are easily within walking distance.
Global warming is effecting the environment- the oceans, wildlife, forests, and everyone. In the arctic, the ice floes help to reflect the light from the sun back int othe atmopshere. As the temperatures have risen, the ice has sstarted to melt, causing sea level to rise and less light to be reflected back into the atmosphere. Thus, more heat and light is trapped, causing the temperature to rise. Polar bears and penguins are affected because they need the ice to survive. ONce the ice is gone, they will go extinct- unless they are raised in zoos or in captivity.
Forest fires may result from the increase in temperature. Winters have been growing shorter and warmer- and spring and summer have arrived earlier. Flowers have started blooming earlier than they ever have- and fruit trees suffer because of the lack of frost. (they need frost for a certain amount of hours to produce fruit later in the season). The forests lack water, and become more prone to catching fire. As for hurricanes, yes, the seasons are changing, the weather itself is becoming warmer and more humid.
I don't believe that there global warming is a hoax. Only lately has it been noticed as a huge environmental problem. I think that global warming should have been addressed a long time ago- and maybe it wouldn't have gotten this bad. People need to realize that we can still help stop global warming or reverse it.
