Barrier Islands
Texas has an extensive coastline that runs along the Gulf of Mexico. If you look closely at the map, you’ll notice that there are narrow islands located just off the coast of Texas. These are called barrier islands.
Barrier islands stretch along about 15 percent of the world’s coastlines. They are separated from the mainland by a shallow body of water. Some barrier islands spread out for more than 100 miles. In Texas, some of the largest barrier islands include Galveston Island, Mustang Island, and Padre Island.
Barrier islands are fragile(脆弱的) areas that contain an interdependent community of land, plants, and animals. All three need each other to exist. If one is harmed in some way, then the other two can suffer. For example, barrier islands are in constant danger of erosion, or loss of land, from wind, waves, and people. The steady movement of ocean waves and wind moves sand along the beaches. This movement contributes to erosion, which changes the shape and size of a barrier island over time. Plants not only provide animals with food and shelter, but it also helps keep an island’s sand and soil in place. When people pick native plants, it advances the process of erosion. This can harm the environmental balance that keeps an island’s ecosystem healthy. For this reason, visitors to barrier islands are usually warned to leave plants alone and to stay on roads and public beaches so that the land, plants, and animals are not disturbed.
As their name suggests, barrier islands provide a natural barrier that helps block the mainland from very bad weather such as strong windstorms and hurricanes. This protection saves lives, homes, and money every year. Barrier islands are also a major source of income for an area’s economy. Padre Island, for example, is visited every year by hundreds of thousands of tourists who take advantage of its sandy beaches and beautiful waters that are perfect for swimming, boating, and fishing. The dollars that tourists spend on the island help financially support the region and state.

It also said that the 70 mph speed limit on motorways should be reduced or enforced to bring down the amount of carbon dioxide given off by cars The House of Common Environmental Audit committee’s latest report said that transport was the only sector（部门）of the UK where carbon emissions have continued to rise since 1990.
It said it was time for the Government to make demand for cheap air impossible by raising air passenger tax. Emissions from air traffic have risen by 5 times as much since 1900 and are continuing to rise.
The committee welcomed the recent introduction of changed car tax, which means that the lowest-carbon cars pay no road tax, while gas-guzzling（耗油的）4×4s pay an increased rate of ￡210. However, the MPs say it doesn’t go far enough and are calling for a top limit of ￡1,800 with lower limit of ￡200.
Committee chairman Tim Yeo said : “Air travel in particular is the fastest growing source of CO2, with emissions more than five times since 1900. The Government should take much more decisive action to reduce the difference of income favor of trains, buses, and lower carbon cars and lorries.”
Friends of the Earth’s senior organizer Tony Bosworth said: “Emissions from transport are still rising and forecasts suggest they will carry on rising for years to come.”
“Tinkering（随意或部分修补）around the edges is no longer enough to deal with the greatest threat the world faces.” A spokesman for the Department for Transport said: “Dealing with carbon emissions in transport is a key problem.”
