The world's biggest container ships have 109,000 horsepower engines which weigh 2,300 tons. Each ship expects to operate 24hrs a day for about 280 days a year. There are 90,000 ocean-going cargo ships. Shipping is responsible for 18-30% of all the world's nitrogen oxide (NOx) pollution and 9% of the global sulphur oxide (SOx) pollution. One large ship can generate about 5,000 tonnes of sulphur oxide (SOx) pollution in a year
(October 2007) A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) (from the Greek word ÏÎµÏÎ´Î¿ÏÎ¿Î´ÏÏ, ÏÎµÏÎ´ÏÏ false + ÏÎ¿Î´ÏÏ foot) is a temporary cytoplasm-filled projection of a eukaryotic cell membrane or a unicellular protist. Pseudopods may be used for motility, or for ingesting nutrients or other particulate matter.
The picture below shows an example of a pseudopod in an amoeba. (Note: in the picture the cytoplasm is called the plasmasol and the cell membrane is called the plasma membrane.) Because the amoeba uses pseudopods to move and capture food, it is classified as a sarcodine.A sarcodine is a protozoan that uses pseudopods.
