Abnormally warm water and human error caused the increasing pollution of water in the Inner Harbor of Baltimore, Maryland, USA. Beginning in January 2012, the average temperature is constantly kept at 6 degrees above normal, which caused the warming of the water in the harbor. Warm water has contributed to early onset of algal blooms, which colored all the water around Baltimore in mahogany or coffee.
Despite the fact that algae — also part of the ecosystem of the harbor, this situation is extremely dangerous for its other components. The higher the water temperature, the lower the level of oxygen in it. This is good for algae, but dangerous to other marine life, especially given the overall pollution level is in the harbor is quite high. This is explained by the fact that in the current year over the Baltimore fell only 60% of normal precipitation. The less rainfall, the less intense is a change of the water in the harbor, which are all harmful substances brought by human activity. Contaminants in agricultural fertilizer, caught in the harbor with the previously dropped out rain, are excellent nutrient for algae, the growth of which disrupts the natural balance of the aquatic ecosystem, as they absorb oxygen from the already depleted water and cover their overgrown bodies sunlight from other microorganisms.
Baltimore authorities once again urge the citizens to reflect on the extent of anthropogenic pollution, leading to the disruption of the balance of life in the environment, an example of which was the Inner Harbor.
