Will we ever run out of FISH ?

 There is a certain feeling of security when it comes to the fish that we eat. Its comforting knowing they always sell fish at Walmart or H-E-B. But will there ever be a lack of fish, or even how we are currently affect the populations of fish and marine life by eating them? Due to the high demand of fish and the constant need for more, various species have already been impacted in a negative way. So what can be done to stop this? Well there is a big demand for fish farms or hatcheries. These farms essentially keep fish in protected enclosures until they reach a desired number and are healthy enough to be released into the wild. Lots of big companies feed the idea of  how the aquacultures have so much potential to deliver a constant stream of food security. But in reality its something we can't 100% be sure of for our future generations. Lots of efforts and money have been put into farming fresh water fish, and branching into farming in the ocean for different species. This can let us believe that we can't ensure there will always be fish on the market for every consumer. So much money is being put into maintaining these fish populations or facilitating the capture of certain fish that prices of those fish are going to rise, and not to mention the addition charges for transportation. These prices will rocket and will be inaccessible to lower income consumers. Although the idea of creating aquacultures will help repopulate fish species it can't be relied on for environmental sustainability. Also the overuse of the aquacultures will create a pressure on marine resources that other species need to survive. But if aquacultures stayed small scale like most freshwater fisheries they could potentially have a great impact on the fish species as well as  acting as a conservatory for the certain species being farmed.

    Do you think there can be other reasons besides overfishing can cause the increase of price in fishes? Like for example, ocean pollution, invasive species, or even environmental changes.

    Would it only affect a certain species of fish? because not all fish species are consumed by humans. As you mentioned, if this happens, it would not only affect us but also the other species that need the fish to survive. It would break the food web tremendously.

Is Hydroelectric Power actually a "Green" Energy Source?

Is Hydroelectric Power actually a "Green" Energy Source? Source: Tennessee Valley Authority (public domain) Greenhouse gases are gases that trap heat in the atmosphere, and the three major greenhouse gases are carbon dioxide, methane, and nitrous oxide. Natural sources of these gases consists of lakes, rivers, streams, and ponds as well. Lakes are environmentally beneficial because they are active, changing, and are important regulators of the three major greenhouse gases. That being said, lakes and reservoirs are known to be built for the purpose of generating power. So much so that water has been retained by dams that the global sea level rise has lowered approximately 0.02 inches per year in the span of 50 years. And since fossil fuels are not utilized to to produce hydroelectric power, lakes are known for their "green" energy sources alternative. Which is a common misconception because it is those lake and reservoirs that release powerful greenhouse gases into t...

Leading Innovation: The Untapped Side of Organic Agriculture

By: Jasmine Rodriguez Organic farming as we know it is has taken off as the main system to diversify plant production to a global standard. The innovation and attention to small details of a sustainable metric excels on all four cylinders such as productivity, environmental impact, economic viability and social wellbeing. With high demands globally, there is certainty to a good balance in how farmers produce crops to meet every sustainable goal required. However, the importance in maintaining sustainability is required to for infrastructure to the economic barriers of organic practices to diversify agricultural farming systems. Some practices that lack sustainability include lack of information and knowledge, unreliable infrastructure and economic halts, and misperceptions to cultural biases. A challenge to the farming system is policymakers forming a certain environment to a greater complex arrangement to a standard sustainable distribution of policies with food and ecosystem security...

Plastic in the Ocean Floor and Shoreline

 When it comes to the use of plastic, we use them all the time in objects that contain the drinks to the laptops that we use for schoolwork. Once they are thrown away, sometimes they can land in the oceans especially when they can leave close there. Because of this, it has caused a big harm to the marine life environment as more plastic debris has enter the ocean water. It can also cause a harm in the birds as well as thousands of birds can ingest the plastic in confusion of food. This was mention in a study by Jose G.B. Derraik, an study that was mention was in 1995 when Robards et al. examined the guts of seabirds two different times during an interval or 10-15 years that there was an increase in plastic ingestion between the year gaps. Now this is not only implying to birds, but they can also be found in the marine life as well. The reason for this is because not only can they be found in the ocean floor, but they can also be mistaken as food for some of the lifeform as well. Th...
