Global Warming Is A Real Threat!
There has been tons of debate over global warming and if it's a real threat or not. Personally, I believe it is definitely happening. Some scientists have the same opinion as me and think something needs to be done immediately, while others believe the earth will just endure everything thrown at it. The levels of Carbon Dioxide, Methane, and other greenhouse gases are rising. More greenhouse gases in the atmosphere, means more of the sun’s energy will be trapped and radiated back to earth. This causes the global temperature to rise.
The temperature rising a few degrees may not seem like a big deal, but it is. A higher temperature may not affect us right away, but it affects certain plants and animals. An example is the Polar Bear. Glaciers and ice caps that Polar Bears live on will melt due to a higher temperature. The poor bears will often drown because they have to swim for so long just to find another piece of ice to rest on. This is slowly but surely wiping out their population. According to scientists, today, Polar Bears are on the edge of becoming extinct. We obviously need to make a change.

The fact that the earth is warming doesn't mean the earth cant withstand it. If its gone through the ice age and far more warmer temperatures and haven't changed the way of the earth. If the earth warms. it wont cause anything threatening to happen to us
ReplyDeleteThe warming of the Earth is obviously affecting the Polar Bears. Soon, they will become extinct, and most of the ice will be melted in the Ocean. No Polar Bears = Messed up food chain. No ice = Rising sea levels.
