Predators have become a colossal problem lowering duck populations and overall nest success and recruitment. With the decline of apex predators such as wolves and coyotes predators such as Red Fox, raccoons and skunks have been able to run rampant and destroy duck populations altogether. The use of predator corridors or the congregation of predators in areas with large duck numbers began to become more prevalent. Nests need to have at least 15% nest success to maintain a minimum number of ducks within the population. That number is hard to maintain when Red Fox are annually killing 900,000 adult ducks within that of the breeding grounds.
Amur Leopard is critically endangered because it’s hunted illegally for its beautiful fur. Their population is estimated to be about sixty individuals, they live about ten to fifteen years in the wild and twenty in captivity. People are trying to save the animal from extinction by monitoring populations, protecting their habitats, and trying to stop poaching and trade. Javan rhinos are critically endangered because of genetic diversity, natural disasters, invasive spaces, and diseases. They are only found in one protected area and there are about sixty of them left.
In Maryland, Nutria greatly impacts the marshes in a negative way because since they breed all year there is no cap to their reproductive capacity, no natural predators in Maryland, and they eat marsh plants (Kendrot). The Nutria greatly decreases the amount of native habitat of the waterfowl and the muskrat. “The Backwater National Wildlife Refuge has lost about 7,000 acres of Olney three-square brush, 53 percent of the remaining marsh was considered to be unhealthy” and will most likely dissipate in the near future (Kendrot). Nutria has impacted many species even humans. The marshes help filter clean water, are areas for young crab and fish to grow.
19/03/2018 Sumatran Orangutans In Indonesia, Extinct By 2025? By The World Wildlife Fund The Sumatran orangutan population has drastically declined to 7,500 compared to a combined total orangutan population of 230,000 a century ago. This significant decline in population has been evident throughout history since 1950s to this current date. It is very apparent that human action whether it is illegal or legal deforestation is driving these immaculate creatures to extinction. Our constant desire for palm oil, business and infrastructure development in Indonesia has caused this major issue.
Many types of the similar trees have been cut down by lumber companies and wiping out important types of trees. Poaching throughout the Neches river was a big problem too, wiping almost a whole deer species out. In different years many good and bad things happened in the Neches river that shapes it up today. Richard wanted to tell every bit of history that Neches River posses and how it all happened the way it did. As much as why it all happened as well.
Another story, that happened in 2010, includes a zoo in China which allowed eleven of its Siberian tigers to die of starvation. Their reason was that the animal’s food was too expensive, so they couldn’t afford it (Carr,2012). In addition, the animals also suffer from medical conditions and usually the zoos won’t bring them to vets or treat them, instead they would let them die (Wild Animals Do Not Make Good Pets, 2016). In an article in 2010, an undercover investigator filmed what he saw at the Tweddle Farm Zoo in England. In the zoo he found dead untreated animals left in their cages and when he took their rabbits to the vet he found that most of them had infections because they weren’t cared for (“10 facts about zoos”, 2010).
The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds. Fortunately, the Viceroy population has increased significantly primarily due to mimicry [Viceroy
Poaching can be considered as illegal selling and trading of animals by killing them for only one part such as an ivory tusk, pelt, or bones or selling them as a whole for a huge sum of money. The vast majority of poaching is due to organized crime to kill and track many animals all at one time without being detected. At these current poaching rates, elephants, rhinos, and other iconic African wildlife will be gone within our lifetime before we know it. Many of Africa’s wild animals have suffered from a massive population decline due to poaching over the past three decades. I personally believe that the animals should be able to
Based on what happened to the rhino population, you are probably able to guess the effect on the sea turtles. There are only about 35,000 nesting females left in the world, which may be larger than the decreasing rhino population, it is nowhere near where it should be. Leatherback sea turtles take a longer than most animals to reproduce, so harvesting their eggs takes a massive toll on the population. You could attribute this decline to other factors as well, but in certain areas poachers have removed up to 95% of the
The number of animals is from 2 – 50 million. Yes, there’s less animals than there are of humans, but what if both animals and humans were to decrease, you may ask? Well, the Circle of Life is one thing, but to have both animals and humans die at the exact time is dangerously crucial. It’s dangerously crucial because there are 16,306 endangered species threatened with extinction, according to www.endangeredearth.com. If those endangered species die out, in addition to our everyday North American Species of birds and mammals, then we have no chance of survival due to BPA still existing.
The risks begin before the insecticide has fully broken down which does not persist for long periods of time. The most affected creature are the bees that are coming into contact with the insecticide. The aerial spraying in North Carolina resulted in the death of millions of honeybees. The product used, Trump, which contains the pesticide Naled, is labeled to be highly toxic to bees. Many beekeepers were not warned about the aerial spraying which resulted in the loss of their colonies.
