Our oceans are turning acidic

During the Nairobi talks, a climate expert indicated that the world's oceans are becoming acidic which pose a big threat to fishes and all marine life. Oceans have already absorbed a third of the world's emissions of carbon dioxide, one of the heat-trapping gases blamed for global warming.
This absorption has turned the oceans acidic. Those of who you have knowledge in Chemistry will know that carbon dioxide when dissolved in water produces a weak acid known as carbonic acid. But high concentrations of the gas could make it quite acidic. Eventually this will prevent vital sea life from growing properly.

Just imagine the consequences. Important marine cannot live long enough to reproduce, as a result there is a shift in ecosystems where fishes are depending on other marine life rather than the one they usually feast on. If fishes cannot adapt to the new situations they will die. This will result in the depletion of total number of fishes in the oceans will decrease because bigger fish depends on smaller fish and smaller fish cannot live long enough. Fishermen who depend on this livelihood will reach poverty if they cannot find any work. This will increase the crime rate in countries and people who eat fish for a living other than fishermen will have to pay quite a sum if they are to eat fish owing to lack of demand.

So basically a slight shift in ecosystem will be catastrophic.

Wildfish will only last 50 more years

After a major scientific study it has been found that there could be only 50 years left for sea fishes. Although there are many reasons behind it and all of you know that pollution is one but eventhough this is out of my topic other such reasons behind it is loss of habitation, fishing, poaching, lack of biodiversity. Remember fishing and poaching are two different things. The survey concluded that at this rate of decline all the delicious fish we eat will expire into the abyss and people who rely on fishes will have to find other species to eat.

Pollution has caused a problem and reduced biodiversity and because of the reduction of biodiversity there are less fish reproduction hence a decline in fish population. Areas of seas that were protected by law from poaching and fishing have survived and fish population increased comparatively.

To some protecting fish stocks by protecting biodiversity does not make sense.

Lets hope for the best.

Fish threatened as climate change warms water

Fish are under threat as climate change causes a rise in temperature. A spokesperson from WWF reported. The report indicated that warmer water means less food, less offspring, less oxygen and more diseases for marine and freshwater fish. Due to fishing the fishes are already stressed and now by climate change, pollution and habitat loss, the fishes are in grave danger eventually affecting us. How are they affecting us? Mainly because they are the still one of the main source of nutritional food.

Fish metabolisms normally speed up in the line with temperature increases, accelerating competition for food and insufficient food supplies can slow growth. Some temperate fish like salmon, catfish and sturgeon cannot spawn at all if winter temperatures do not drop below a certain temperature.

In lakes in particular, warmer temperatures hamper the circulation of oxygen that fish need to breathe. Fish filter oxygen from water but amount of oxygen dissolved in water decreases as temperature rises.

Warming could cause the fishes to dive deeper into cooler waters to maintain their normal habitat. However it will cause a greater strain on other species such as birds who dive into the water to catch fish. However as the fishes are way below the birds will starve and die. In 1993 as fishes moved to cooler waters around 120,000 sea birds died. This figure was posted by WWF.

China's Enviornmental disaster

The explosion at a chemical plant in China. Eventhough this is old news, i need to say it cause i think this explosion may lead to a great ecosystem imbalance. During the explosion the chemical, benzene leaked into the river Songhua polluting the river and eventually made it impossible to drink water from the river.

It not only affected China, the toxic chemicals also entered Russia. According to reports a chemical cadmium a potentially cancer-creating chemical also flowed to a tributary of Yangtze River.

So you can imagine when toxicating a river the lives of fishes and aquatic animals are in great risk. Pollution not only affects animals but it also affects us. Although the explosion is an accident we have to learn to be must more careful and cautious or else things could get worse...
