Sustainable Fishing

Posted on by

When it comes to the fishing industry there are a lot of issues of sustainability. Whether it is in the catch size, techniques used, areas fished in, or bycatch. Bycatch is the accidental catching of the not target species. In most cases, these marine life forms are often killed before they can be released back into the ocean. Bycatch poses another major issue within the already difficult overfishing problem.

This graph is based on data from the FOA regarding catch sizes between the years 1950 and 2018. This graph shows the growth trend of the fishing industry and as more sustainable attitudes developed a slower decrease in catch size in the more recent years. The lowest catch was in 1950 with about 250,000, the highest being in 2002 with catch sizes around 850,000. The size eventually drops down to about 680,000 in 2018. Based on this larger drop in 2018 and information from the NOAA and FOA this number aims to be lowered even more. Protecting marine populations will increase the likelihood that these populations can survive and repopulate in order to sustain future generations.

Fast Fashion and It’s Consequences

Posted on by

Many companies involved in fast fashion and unsustainable practices use outdated and less eco-friendly processes to produce their goods. A a result of these outdated manufacturing practices, the carbon footprint of many clothing brands are alarmingly high. Fast fashion caters to increasingly high levels of supply and demand, so the products are over produced, and then retailers buy them at exceedingly high prices. Whatever is left over are usually disposed of unethically, rather than being donated or up-cycled. Brands like Aerie, She-in, and the like are some of the biggest contributors to this issue. However, there are viable, and fun alternative solutions to this issue that not only are sustainable, they’re also very much within current fashion trends and practices. As mentioned earlier, up cycling is not only an alternative option, it’s also affordable. Thrifting is also a popular alternative, and it’s also way more affordable than buying at full price in-store. Savers, Goodwill, and the Salvation Army are all large and fairly well known companies that utilize thrifting practices. There are several benefits to thrifting and buying clothes which include, but are not limited too, lesser levels of air pollution, less waste production, and healthier oceans. It turns out that polyester, which is used in many fabrics, doesn’t decompose in water, and instead just adds to the pollution of our oceans. Strikingly enough, people throw away 60-80 pounds, on average, of unwanted clothing over the course of their lifetimes. The fashion industry also contributes to ~10% of global carbon emissions. So, it is not unfair to state that thrifting is, in fact, good for the environment, and it’s also wicked fun.

Oceans and Marine Systems

Oceans cover the largest portion of Earth’s surface (71% of Earth’s surface is water and oceans makeup 96% of Earth’s water supply). It’s extremely important to consider and be concerned about our oceans and what climate change and human activity is inflicting upon them. Sea-level rise, ocean acidification, overfishing, pollution, ecological collapse, dead zones, and more. Within each of these larger problems are more sub-problems. Sea-level rise and polar ice caps melting, ocean acidification and the bio-pump, overfishing and bycatch, and pollution and micro plastics (the Pacific Garbage Patch is currently 1.6 million square kilometers). Humanity relies heavily on oceanic processes and marine resources, if more sustainable practices were used and enforced the ocean (and the global environment) wouldn’t be in such a compromised position. The ocean also acts as a HUGE carbon sink so not only do human lives revolve around the ocean in the literal resource sense but it is also taking in so much of the carbon humanity produces. The ocean can’t take in carbon forever, the effects of this are already been seen in phytoplankton and zooplankton, the ocean is becoming warmer and nutrient deficient which will have cascading effects on marine food chains.

Is Climate Change at a point of no return? The impact of CO2.

The first class that I took which dove deeply into understanding climate change and its routes was AP Environmental Science my junior year of high school. I took that course in 2018 and have not taken many classes since that contain the same overlapping topics. Because it has been a few years since I learned deeply about the climate change, I focused my research for this blog post about how green house emissions have altered since then and whether or not climate change is reversible. In my readings, I learned that before the Paris Climate Agreement of 2014, it was expected that the Earth’s average temperature would increase by roughly 4.2* celsius by the end of the century would which would have proven to be catastrophic. However, with the advanced focus on saving our planet, the curve has shifted downwards in the last few years projecting a 3* increase, which still is dangerous but there is more room still for the curve to shrink. A huge reason for the positive trend in the temperature curve is due to the increasing availability of save and renewable energy sources such as electric cars, solar, and wind options. The worlds average ocean temperature is roughly 17* F which is one of the main sources of projecting the climate change curve. A shift in that temperature of even .25% either direction will reverse the positive shift in the curve. Water temperature as well as temperature on land again is all directly correlated to green house gas emissions and an abundance od CO2 in the atmosphere.

Carbon Dioxide and its effects on Coral Reefs

Posted on by

Carbon Dioxide is a powerful greenhouse gas that has been at the center of political discussions surrounding Climate Change. As humans release more CO2 into the atmosphere, the “Greenhouse Effect” causes the earth’s temperature to rise, having devastating consequences for life on earth. While much of the CO2 stays in the atmosphere, a huge amount of the gas is absorbed into our oceans. This has terrible consequences for life on the seas. Coral Reefs have taken the brunt of this damage. Coral Reefs are dying at an increasing rate. This is a major problem because “Coral reefs specifically contribute to more than half of the oxygen our planet relies on, and these are vanishing at an unprecedented rate” (Gannon). This will have terrible consequences for other forms of life, as well as for humans. Unbelievably, “Over 2,838,240 acres of coral reef are lost every year, totaling an area 10x the size of New York City” (Gannon). This is a terrifying figure. Regardless of whether people want to admit that this is going to have terrible consequences for humans, it will. Human beings need to come to the realization that as a global community, we need to figure out a way to reduce the amount of CO2 being released into the atmosphere.
