Whether you believe in climate change or not, the affects of pollution on the environment are plain to see. In her 2017 article entitled “Why Tearing Down Dams Could Save Endangered Killer Whales,” Hanna Brooks Olsen examines the effect of declining Chinook Salmon population on pregnant Orcas near Seattle.…

According to the Earth Institute, each year, one trillion plastic bags are consumed worldwide.Plastic bags are harming the ocean. There should be a fee on plastic bags. Polluting is happening everywhere the reason this is happening because people are careless and sometimes bags slip away and the bags just fly away and go up in streets.The birds are also mistaken the plastic for food and giving it to their babies.Their should be a fee on plastic because the plastic is polluting the oceans and…

Whereas pollution is very apparent in water, the increase in death rate in aquatic animals are rising every year. People under the poverty line are not able to have access to clean water increasing the rate of disease. This should be addressed by the government because, if pollution increases day by day, it can slowly start to affect everyone in the world, increasing the death rate. We, as the environmental and public works committee, believe that water pollution is affecting the nation and it…

Welcome to the most colossal biome on Earth, the marine! This ginormous place on Earth is home to many plants and animals within its many oceans and three different levels. Pacific, Atlantic, Arctic, Southern, and Indian are the five main oceans on this planet. Each ocean is separated into three levels, known as euphotic, disphotic, and aphotic. The euphotic zone is also known as the sunlight zone, this is the top layer of the ocean and it receives almost all of the sun's rays. The next section…

Metacognition described by Chick is the “awareness or analysis of one’s own learning or thinking processes.” This is important in learning more about local issues of a political nature because when events are happening near you it is more likely to affect you and your life than if it was somewhere else in the nation. It is important to know the problems happening around you, so you can help find a cause or come up with a solution to solve this issue. With the actions happening around you it will…

Sand dune erosion is occurring on the Cronulla coastline due to the coupling of human and natural impacts and is gradually resulting in the beach being less able to be protect itself from natural implications. The constant sand dune erosion is creating a steeper slope this is allowing waves and winds to rapidly remove sand from the dunes. The sand dune erosion is destroying habitats from plants and animals, this is substantially decreasing the biodiversity on the coastal environment. Sand dune…

Velellas, a genus of cnidarians, are more on the odd looking side. These common jellyfish- like creatures are found on the North American West Coast. Though they don’t have a traditional “medusa” or “polyp” looking form, their body shapes are more of a flat, disk- like colony of specialized personal polyps and are about 6- 7cm in diameter.. They generally live in warm to warm- temperate waters and oceans and live off shore. Due to them mostly floating above water, they have a vibrant blue color…

Research Proposal Ocean pH Levels and Shellfish Survivability Josh Lewis Abstract: Ocean acidification is a growing issue that is causing young shellfish to die, which is hurting marine ecosystems. Research has been done on the topics involved (pH levels, effects of ocean acidification on shellfish, etc.) many times, and though it’s a slow moving issue, it is evident. As I stated, this is an extremely important topic to know about because thriving marine ecosystems are being damaged. As…

Shark fins, the main ingredient found in shark fin soup, can be highly toxic to humans, additionally, it poses many serious threats to human health. Shark meat, including fins, contain high levels of BMAA, these high levels could pose a major threat to the consumer’s health. A recent study by the University of Miami found high concentrations of beta-Methylamino-L-alanine, or BMAA, in shark fins. BMAA is a neurotoxin linked to many neurodegenerative diseases in humans, such diseases include…
