A cargo ship discharging ballast water into the sea. Ballast water discharges by ships can have a negative impact on the marine environment. [1] Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever ...
Two hours after insertion, the Ablestar upper stage exploded. Even boosters that don't break apart can be a problem. A major known impact event involved an (intact) Ariane booster. [58]: 2 Although NASA and the United States Air Force now require upper-stage passivation, other launchers – such as the Chinese and Russian space agencies – do not.
Visualisation showing how mass accumulates in gyres. The size of the patch is indefinite, as is the precise distribution of debris because large items are uncommon. [51] Most debris consists of small plastic particles suspended at or just below the surface, evading detection by aircraft or satellite.
1969: five sailors on a Japanese ship were injured when space debris from what was believed to be a Soviet spacecraft struck the deck of their boat.

Are cruise ships the main source of noise pollution? Passenger cruise ships represent significantly less than 1% of all oceangoing vessels, according to Cruise Lines International Association, the ...
Norwegian Dawn and Carnival Dream moored alongside in New Orleans (2015). Cruise ships carrying several thousand passengers and crew have been compared to “floating cities,” and the volume of wastes that they produce is comparably large, consisting of sewage; wastewater from sinks, showers, and galleys (); hazardous wastes; solid waste; oily bilge water; ballast water; and air pollution.
The health and environmental impact of transport is significant because transport burns most of the world's petroleum.This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide.
