In the movie, The Day After Tomorrow, many climate changes including an ice age are caused by global warming. Much of the science in the movie has been questioned by people. However, there may be some truth to the idea in the movie that global warming could cause an ice age.

The theory starts with an understanding of why Europe and Scandinavia are not colder already. After all, other places at the same latitude(纬度) are covered with ice. The ocean current called the Gulf Stream brings warm waters from the Caribbean to the UK and Europe. These waters warm the countries around their path. This is why the UK, Europe and Scandinavia have a warmer climate than Alaska. Global warming has nothing to do with this. Global warming is significant. It could slow the Gulf Stream, or even stop it. If this were to happen, the cold waters would stay in the area of Europe, the UK, Scandinavia and the Northeastern US. It could mean an ice age for those regions.

Some weaknesses in the Gulf Stream could happen for different reasons. These days, it could happen due to global warming, caused by human activities, such as the burning of fossil fuels.

If a new ice age happened, it would probably be caused by the melting of the polar ice. This will lead large quantities of cold and fresh water to come into the ocean, which would disrupt the Gulf Stream and cause the cooling of many areas that now have a mild climate.

Scientists have gathered a lot of data from the oceans and the land to try to determine whether an ice age could be caused by global warming. With all this information at hand, it appears that it is indeed possible that global warming could lead to an ice age.

Not only does the use of plastic water bottles hurt your wallet, it also increases pollution and wastes energy and water. Only 23% of all plastic in America ends up in a recycling bin, meaning over $1 billion worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho.

It is a convenient, clear water bottle that can either be drunk or eaten. To drink it, you can either peel off the membrane(薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡) without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events, such as marathons, music festivals, and sporting events, where tons of plastic bottles are used, and frequently left behind as litter. And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.

The team has been working for the past two years to develop the technology and materials needed to produce Ooho; they have recently applied a patent(专利)for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles. It has appeared at events in London, San Francisco, Boston, at conferences, festivals, and so on.

Ooho is catching many people's attention and has raised over $1 million and gained 1, 000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer's interest while the production machine is getting up and running. It is quickly making a rise, so keep an eye out this year for these bottles of the future.

Molai grew up in a tiny village in India. The village lay near some wetlands which became his second 1. He learned the value and beauty of 2 there from a very young age.

When he was 16, Molai began to notice something 3 happening around his home. A flood had hit the area earlier that year and the 4 it caused had driven away a number of birds. 5, the number of snakes had declined as well. He 6 that it was because there weren't enough trees to protect them from the 7. The solution, of course, was to plant trees so the animals could seek 8 during the daytime. He turned to the 9 department for help but was told that nothing would grow there. However, Molai went looking on his own and 10 a nearby island where he began to plant trees.

11 young plants in the dry season was 12 for a lone boy. Molai built at the 13 of each sapling(幼树)a bamboo platform, where he placed earthen pots with small holes to 14 rainwater. The water would then drip(滴落)on the plants below.

Molai 15 to plant trees for the next 37 years. His efforts have resulted in 1, 360 acres of naturally-grown land that has become home to many plants and animals.

Pollution takes away all the beauty of the beaches of Hawaii. I hate to go to the beaches on (sun) weekends and see rubbish bags lying on the sand, cigarette butts(烟头) (bury) in the sand, and soda cans floating in the ocean.

One thing that really annoys me is that I see (tour) who visit Hawaii leave their rubbish on the beaches. I was always taught after drinking soda to throw the can into the place it should stay—the trash can. Another thing that annoys me is that some people walk right by rubbish  pretend that it's not there.

The dogs or the fish are not to blame it. It's our fault and we must blame (we). Everyone has to do his or her part (solve) this problem. It can't be difficult to do the job. There are a lot of things that we can do. First of all, we can help pick up rubbish along the beaches. We could also form organizations that help clean up our beaches. More(important), we need to start now before the beaches (damage) beyond repair.
