Tension is mounting as opposing sides continue to polarize. Threats are made, property is damaged, people are endangered; all because of a slimy, recreational resource in our lake. Fish are causing a division among fishermen. Mostly between two types of fishermen: rod-and-line fishermen and spearfishermen. There is a lot of arguing about whether spearfishing should be allowed as their ability to go down and shoot whatever fish they want reduces the trophy fish population of a body of water.
Coral reefs around the world are endangered and close to becoming extinct. Coral reefs are in danger because of many factors, one being humans and the other is based on nature and ocean acidification and other such elements within the water and climate itself. Coral reefs are vital to our ecosystem because of the thousands of species they house as well as the part they play in the food chain. Coral reefs are a ‘canary in the coal mine’ for the health of our planet.
Aquaponics is the idea of creating a self sustaining ecosystem, that mimics nature, to grow plants (agriculture) and fish for consumption. A basic aquaponics system has two subunits, a fish tank and growing bed for plants. The fish are the start of the system, they create fish waste (specifically ammonia) that is 'fixed' by bacteria into suitable plant fertilizer. The water containing the waste is then pumped up to the grow bed and run past the roots of the desired plants.
Ocean acidification is a rising problem on Earth. It is a term used to decribe the rising acidity in the oceans. 1/3 of the carbon dioxide we edmit from burning ficil fuels is absorbed by the oceans. This equals to 1 million tones every day. When the carbon dioxide disolves into the sea water, the H2O and CO2 molecules combine forming carbonic acid (H2CO3). This changing chemistry is causing our oceans to become more acidic. Over the past 200 years the acidity has risen by 30%. The pH of the oceans has droped by 0.1 pH units (from 8.2-8.1).
I've been researching deep sea life. Organisms close to the ocean floor live in a very dark area, sunlight cut off hundreds of meeters above where they are located. Some organisms can generate enough energy to create thier own flashes of light, this is called bioluminescence. This is the biggest lightsource that is ever seen at those depths.
