More proof that we are killing our oceans

There is undeniable proof of the damage caused by the waste produced by humanity, if one will just open their eyes to what is there. Here we have a view of the coast of California, near La Jolla, San Diego. Here is the decay of algae.

Dead zones are areas of low-oxygen within the planets oceans. This is the result of an increase in chemical nutrients, typically from sewage, urban land use, and fertilizers. While dead zones can be naturally occurring as well, from coastal upwelling and changes in wind and water circulation patterns, there have been a significant increase in the appearance of these across the world. There were 146 dead zones reported in March 2004, and 405 as of 2008.

The pressence of dead zones result in reduced reproduction of marine life and often the suffocation of life within it for prolonged periods. Some areas are classified as dead zones for only a few hours of the day. Even this short time span can mean death for slow moving bottom-dwelling creatures.

Fortunately the existence of dead zones are not permanent. Changes in weather are natural, and do have an effect on the creation and dispersion. Even those created by humanities actions can be undone. The Black Sea, considered the largest dead zone in the world, has been mostly cleared out since 2001, after the coastal countries had a reduction in the use of their fertilizers. Fishing has again become prominent in the area as a result.

Our actions have noticeable effects upon our planet. Our reactions do as well. If we become aware of the mistakes that are made, and take action to right them, we can avoid any future disasters. Every action has a result. The more profound results come from actions with forethought.
