Alaska is perhaps the most amazing state in the USA. It has coaslines facing both the Arctic Ocean and the Pacific Ocean. This state has an incredible three million lakes. That’s four lakes per person living there. Many cities in Alaska cannot be reached by road, sea, or river. The only way to get in and out is by air, on foot, or by dogsled. That’s why Alaska has the busiest sea airport in the world, Lake Hood Seaplane Base. Nearly two hundred floatplanes take off and land on the water of this airport every day. It’s really a fun scene to watch. Alaska is called the Land of Midnight Sun because in summer, the sun does not set for nearly three months. But in winter the sun stays almost unseen. All Alaskans take special pride in their beautiful and unique state.

Our oceans are becoming extremely polluted. Most of this pollution comes from the land, which means it comes from people. Firstly, there is raw sewage, which is pumped directly into the sea. Many countries, both developed and developing, are guilty of doing this. Secondly, ships drop about 6 million tons of garbage into the sea each year. Thirdly, there are oil spills from ships. A ship has an accident and oil leaks from the vessel. This not only pollutes the water, but it also kills marine life. Next, there are waste materials from factories. Without proper regulations, factory owners let the waste run directly into the rivers, which then leads to the sea. And finally, oil is washed from land. This can be the result of carelessness or a deliberate dumping of waste.
