• Bradford Pear Trees: The Harm of Invasive Species

    In the early 1900s a vibrant flowering tree was introduced to the US from China. Its beauty and blight resistance made the tree popular and fastspreading during the 20th century, quickly becoming one of the most popular ornamental trees in North America. When the late 20th century came around it took a turn for the worst and became the single most hated tree across the continent. The Bradford pear tree is a reminder of the consequences of human interaction on non-native species.

    The tree first came across the seas from China as a combatant against the blight that devastated the American orchards in that time period. By the 20th century, it had evolved into a staple within American suburbs. Its rapid growth and aesthetic beauty made it attractive to everyone. The tree thrived in polluted air, compact soil, and tightly developed spaces which led to a prevalence in environmentally discriminated areas. All of its outstanding qualities that fit the American dream made it the ideal choice for mass planting. The governments pushed them as the perfect tree for aesthetics leading to a boom in its spread across North America. But what began as a solution quickly spread into a problem. Every step taken that led to the tree’s rise was because of the little consideration to the long term ecological impacts that the invasive would cause. In the 1990s their invasive spread became suffocating due to their reproduction with alternate pear trees, leading to state wide initiatives to root them out.

    The hate arose from the absolute weakness of the trees. They could barely withstand strong winds and led to mass city cleanups to maintain public safety. The most critical complaint was the stench of the trees. They emitted a rotting scent leading to an increase in pollinators and detriment to humans. They began to quickly outnumber native species and overtake entire ecosystems. They failed as food sources for local wildlife and decimated the local trees, eradicating biodiversity from areas.

    Today, the trees are deeply hated across the United States and are symbols of sheer human ignorance over nature. In the pursuit of beauty, scientists prioritized short term solutions over long term consequences. Their aesthetic convenience leads to the harm of our ecosystems. They stand as a symbol of the potential damage of non-native species can cause to ecosystems and serve as a reminder to hold onto environmental consideration.

    The trees don’t just represent ecological damage but the heavy impact of environmental discrimination as well. Environmental discrimination is the harmful decisions that disproportionately affect low-income communities and communities of color. While the trees did affect all communities, the initiatives to remove them mainly occurred in wealthier areas. This has led to marginalized communities to bear the maintenance costs of the trees and an increase in the urban heat island effect from poor shade. All of this is due to the poor long term thinking of city planners and ignorance of the trees ecological damage. While the trees stand as a mistake, the environmental discrimination they led to is most certainly not.

    The Bradford pear tree acts as a warning of the dangers of invasive species. They aren’t the only invasive species to affect ecosystems and they won’t be the last. True long term success and environmental care requires thoughtful planning and ecological diversity that is washed away by the dangers of non-native species. Environmental decisions are never neutral – they have costs that may span generations.

  • Sharks: The Real Threat?

    A deep dive into the worlds most misunderstood creature

    Imagine toasty warm… radiant… bright:  Sunny. Sandy. A shell-covered beach… A jump into the ocean…  A relaxing swim– BUT– all of a sudden down, deep down in the depths below you spy a dark ominous shadow. Panic immediately seizes your heart and the word “Shark!” swarms your mind. After that split second you begin to realize it’s just a large fish. The truth is that the odds of that nightmare moment you built in your head only has a 1 in 3.7 million chance of occurring. A statistic that has been blown wildly out of proportion by the media. We have been conditioned to dread them. But before we allow that fear to take hold of us, we have to ask: What is the real threat– sharks or us?

    So why does this fear plague everyone? For decades society has grown up consuming media portraying a twisted image of sharks– Jaws, 47 meters down, and Sharknado. These films have all created a warped perception around them that have struck fear in the hearts of millions around the world. This fear has built a society with very little sympathy for the 100 million sharks killed by humans each year. 

    Sharks guard our oceans. As apex predators, they are crucial in maintaining the balance of the marine ecosystem. They work as population control by preying on any animals that are weak, sick, and overabundant. This prevents the overpopulation of one species that may throw the ecosystem off balance. Sharks not only control the prey population, but also protect coral reefs. If the number of sharks is down in a reef it causes a significant rise in the number of mid-level predators. An overabundance of mid-level predators leads to the decline of herbivores, allowing algae to overwhelm corals. When sharks prey on the weak and sick, it prevents the prey from reproducing. This works as natural selection and only the strongest may escape the jaws of the sharks. This strengthens the fish population and reduces the number of ill that may pass disease onto others. Sharks command a presence of fear throughout the ocean that promotes biodiversity. Their presence influences where animals dwell and keeps them from dominating areas which allows many species to coexist and create a healthy habitat. Sharks not only aid the ocean but the climate as well. They enhance blue carbon, carbon stored in oceans, by maintaining the ecosystem. By helping the ocean store carbon, they mitigate the effects of climate change. 

    Despite being the apex predator, sharks face their greatest threat from humans. One-third of all known shark species are at risk of extinction. The perpetrator? Overfishing. It claims the lives of 274,000 sharks every day. The global abundance of sharks has decreased 71% in the last 50 years. Roughly 73 million sharks per year are taken just for their fins. Shark fin soup, a delicacy throughout Asia, is a status symbol. Sharks targeted for their fins aren’t killed, instead their fins are sliced off and thrown back into the ocean. Without their fins they will sink to the ocean floor and slowly suffocate. It is the complete destruction of 400 million years of evolution for soup. Bycatching, the unintentional catching of non-target fish, steals the lives of 80 million sharks annually. Sharks caught often die in the nets from stress or suffocation. Their brutal end serves no need for survival, only profit.

    Sharks are critical to the ocean. Their absence will lead to a potential collapse of the food web and widespread damage to the ocean. Coral reefs will begin to degrade, destroying homes for countless species. Sharks have roamed the seas for over 400 million years but in just a few decades we have pushed them to the brink of extinction. We can no longer stand by and watch as sharks are being hunted in their home. Not only is this an environmental failure, it is also an ethical one.

    If we continue allowing misinformation to strike fear in our hearts, we risk losing these awe inspiring creatures. It’s time to acknowledge the injustice. Sharks deserve better. We can do better. It is time to make a choice– fear them, or fight for them. They are not the villains of any story– we are. But this doesn’t have to define us. Everyone can do their part by educating others on the massacre occuring. Share the truth. Show others the importance and beauty of sharks. Because if the ocean’s top predator is dying by our hands, what does that make us?
