Direct your child to trace each number following the direction of the arrows to learn the proper formation.
Marine debris can enter the ocean in a variety of ways. From land, trash may be carried to the ocean in rivers or storm and sewage drains, swept from the beach by waves and surf, or blown offshore by winds, especially during heavy storms.he most common way to measure floating plastic in the ocean is to collect it using very fine-meshed nets towed at the ocean surface from a ship. At SEA we have been measuring plastic debris using this method for more than 25 years.
Where does it go? Much of it ends up on our beaches washed in with the waves and tides, some sinks, some is eaten by marine animals mistaking it for food. Other forms of pollution impacting the health of the ocean come from a single known sources like an oil spill or from accumulation of many dispersed sources like fertilizer from our yards. The majority of pollutants going into the ocean come from activities on land. Natural processes and human activities along the coastlines and far inland affect the health of our ocean. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Nonpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, livestock ranches, and timber harvest areas.
