Dolphins and Sea Lions used for protection

Puget Sounds will soon have dolphins and sea lions protecting and patrolling it's submarines from terrorist attacks. The U.S. Navy is training them and this method is already being used in other parts of the world. Supposedly, dolphins and sea lions are more capable of detecting a lone diver than the most advanced technology. Dolphins can outswim any human and the sea lions have good directional hearing. So while this seems like a good idea at first, many people are apposed to it for various reasons.

Washington State animal lovers and environmentalists are worried that the dolphins will suffer in the cold waters of the Puget Sound and that the local environment will suffer from the loss of these animals. Public hearings are being held in Seattle and in towns along the Puget Sound to decide whether or not this should be allowed. Although, the dolphins could really contribute a lot to this area, protesters say that dolphins just don't belong in the northern Pacific waters. The dolphins are accostumed to waters that are 10 degrees warmer than the waters in the Puget Sound. The navy argues back that the dolphins in the cold water of Alaska and Norway have suffered no ill effects.

Although it would be really cool to have dolphins protecting and patrolling against terrorists, dolphins are not made to do this for us. Its not in there natural state. By doing this who knows how far we will go in the future with using animals for the common good of humans.

Which water bottles to stay away from

Last summer, I used a water bottle with the recycle number 7. I carried it around with me almost everywhere I went without knowing that the plastic could be leaking harmful substances into my water. One day, my friend told me that I should get a different water bottle because of the recycle number on it. I never thought much of it and just didn't really care. But then one night my family was talking about it over dinner and I thought to myself that I really should get a new one. I started to look in my cabinet for another water bottle and every single one had the recycle number 7 on the bottom. So I just continued to use the one I had because I was too lazy to go out and get a new one at the time.

Recently, I found an article talking about the recycling numbers on water bottles. It talked about the what the numbers meant and which ones are safe to use. Most of the colorful, hard plastic water bottles are made out of polycarbonate plastics, which have the recycling number 7. But there is an alternate you can use: #2 HDPE(high density polyethylene) water bottles that can come in the same colors, sizes, and shapes. So next summer, I am going be sure to get a water bottle with the #2 to prevent myself from getting chemicals in my body.
