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.
Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains over 13,000 species, most of which are terrestrial. Although their name suggests they have myriad (10,000) legs, myriapods range from having over 750 legs (the millipede Illacme plenipes) to having fewer than ten legs.
