Why Animal Extinction Matters

The earth’s ecosystem is made up of a delicate balance between various plant and animal species. Every living being on this planet is interconnected and relies on each other for survival. However, the rapid rate at which animal extinction is occurring is disrupting this balance, posing a threat to both animal and human survival.

Many people might argue that the extinction of animals has no direct impact on humans. But the reality is far from it. Animals are critical for the health of our planet, and without them, our world would be a drastically different place. Every species plays a unique role in its ecosystem, contributing to its balance and function.

When a species goes extinct, it creates a domino effect on other species in the ecosystem. The disappearance of one animal can impact the entire food chain, leading to the decline of other animals. It can even affect the availability of essential resources such as clean air, freshwater, and fertile soil. Ultimately, the extinction of one species can put the entire ecosystem at risk of collapse.

Apart from ecological concerns, animal extinction has a considerable economic impact as well. Many industries, such as agriculture and fisheries, rely on the ecosystem’s services and the survival of the animals that live in it. Moreover, the loss of wildlife tourism can impact the economy of many countries.

The Impact of Endangered Species on Ecosystems

In 1973, the Endangered Species Act was established to protect imperiled species and their ecosystems. This act recognizes the importance of preserving biodiversity for the well-being of humans and the environment. The implications of extinction go far beyond the loss of a species itself. It can impact food, water, the environment, and health. Unfortunately, the rate of extinction is occurring at an alarming rate, 1,000 to 10,000 times faster due to human activity.

The modern causes of extinction are numerous and complex. They include the loss and degradation of habitat, over-exploitation, invasive species, climate change, and nitrogen pollution. The loss of a species can cause cascading effects through the food chain, known as trophic cascades.

For example, the reintroduction of wolves in Yellowstone National Park caused an increase in the population of their prey, the elk. This in turn allowed the vegetation to recover, and the landscape to be reshaped. Similarly, the decline of kelp forests due to the disappearance of sea otters in California has led to the growth of sea urchins, which consume the kelp. The decline of kelp forests not only affects the biodiversity of the ocean but also impacts the fishing industry.

California sea otters used to number in the hundreds of thousands to millions, but their population has been reduced to about 3,000 due to unchecked hunting and pollution. These adorable creatures play a critical role in maintaining healthy kelp forests, and their decline can have detrimental effects on the ocean’s ecosystems. Losing such an iconic species will affect not only the kelp forest but also the fishing industry, coastal tourism, and local economies.

Specific Examples of Endangered Animals and Their Importance to Humans

As humans, we tend to focus on our own needs and survival, often forgetting the interconnectedness of all living creatures. However, the extinction of certain animals could have dire consequences for our own well-being.

One example of an endangered animal with significant importance to humans is the honeybee. These tiny insects play a crucial role in pollinating crops, helping to produce roughly one-third of the food we eat. Without honeybees, our diets would become significantly less varied, and food production would decline dramatically.

Another example is the elephant. These majestic creatures are not only beautiful, but they also play a crucial role in maintaining healthy ecosystems. Elephants are known to uproot trees and create clearings in forests, which helps to maintain biodiversity and provides habitat for other animals.

Sea turtles are another species at risk of extinction, but their disappearance could have serious consequences for humans. These ancient creatures play a crucial role in maintaining the health of coral reefs, which provide habitat for countless marine species and protect coastal communities from storms and erosion.

The list of endangered animals goes on and on, and each species plays a unique and crucial role in maintaining the health of our planet. From the tiger to the rhinoceros to the polar bear, every creature is a piece of the puzzle, and their loss could have a domino effect on the entire ecosystem.

It is clear that we need to take action to protect endangered animals not only for their own sake but also for ours. By working to preserve their habitats and prevent their extinction, we are ultimately working toward our own survival and the survival of future generations.

The Consequences of Losing Endangered Animals

The extinction of animals doesn’t just impact the creatures themselves. It can have devastating consequences for humans too. Here are just a few examples:

– The loss of endangered animals can make people sicker: Many endangered species play an important role in controlling the spread of disease. For instance, bats eat insects that transmit diseases like malaria, while certain frogs secrete compounds that have antibacterial properties. Without these animals, the incidence of disease could rise.

– It can decrease water and air quality: Endangered animals also help to maintain the balance of ecosystems. For example, sea otters keep sea urchin populations in check, which prevents overgrazing of kelp forests. Without otters, kelp forests can be depleted, leading to the erosion of coastlines and a decrease in water quality. Similarly, bees and other pollinators are crucial for plant reproduction and help to purify the air we breathe. Without them, air quality could decrease.

– It can hurt our ability to grow and gather food: Many animals help to maintain the health and fertility of the soil, which is essential for growing crops. Without these animals, food supplies could dwindle. Additionally, the loss of marine species can impact the livelihoods of people who rely on fishing.

– It can deepen the impact of extreme weather events: Endangered species also play an important role in mitigating the effects of extreme weather events. For instance, wetlands help to absorb excess water during floods, while forests can help to prevent soil erosion and landslides during heavy rains. Without these ecosystems and the animals that live in them, the impact of extreme weather events can be much worse.

– It can weaken our ability to combat climate change: Many endangered species help to capture and store carbon dioxide, a greenhouse gas that contributes to climate change. For instance, forests absorb CO2 and convert it into oxygen, while ocean plankton absorbs CO2 and produces oxygen as well. Without these species, the level of CO2 in the atmosphere could increase.

– It can make us miserable: Finally, the loss of biodiversity can have psychological and emotional impacts on humans. Research has shown that people who are exposed to nature tend to have lower stress levels and better mental health. The loss of endangered animals and their habitats can lead to feelings of grief, loss, and despair.

The Role of Humans in Preserving Endangered Species and Our Own Survival

One of the most important ways humans can help preserve endangered species is through the Endangered Species Act (ESA), which was passed in 1973. This act is designed to halt the rapid loss of plant and animal life and is the only piece of environmental legislation that does not require a cost-benefit analysis before going into action. The ESA ensures that any species declared threatened or endangered will be protected, and efforts will be made to assist in its recovery.

Preserving species is crucial not only for ecological reasons but also for medical and aesthetic/recreational reasons. Over 50% of the 150 most prescribed medicines were originally derived from a plant or other natural product, making it clear that we rely heavily on the diversity of nature for our own well-being. Furthermore, the American tourism industry is dependent on plant and animal species and their ecosystems, meaning that their loss could also have a significant economic impact.

Of course, humans can do much more than just rely on the ESA to preserve endangered species. Individuals can get involved in conservation efforts, either by volunteering their time or donating to organizations that work to protect wildlife. Additionally, people can make choices in their own lives that help reduce their impact on the environment, such as using sustainable products and reducing their use of single-use plastics.

Ultimately, the link between animal and human extinction is clear, and we all have a responsibility to do our part in preserving endangered species. Whether through supporting the ESA or taking more direct action in our own lives, each of us has the ability to make a difference in ensuring our own survival.–MM
