There are many hypothesis to why this had occured, such as rising global erosion rates, which is caused by humans and their consumptions. Overall, it is not one cause that is leading to the due of less oxygen but to many other reasons that converge.

Even though their status has been moved up to vulnerable, this species is having resources taken away incredibly fast. Humans are the reason behind all of the previously listed reasons for the snow leapord's endangerment.

All these years of the ocean taking in carbon dioxide has made a large effect. The ocean as a whole has lowered its pH by 30%. This is making the ocean more acidic. When there is not a balance in the pH, coral reefs are decaying because corals cannot make exoskeletons with the increased acidity. 25% of all ocean life lives in coral reefs. This will effect ocean life greatly.

GMO stand for genetically modified organism. When an organism is exposed to chemical pesticides amd herbicides, it will change non- naturally and may hurt the animal. The organism might not adopt to it new features and will die, thus ending the species. Or GMO feature helps the animal and then produce more. If it produce more, it will over populate and causing more problems. GMO plants are unhealthy for animal and human. It is not natural to eat somthing with pesticides and herbicibe is bad for the body and may cause cancer or disease.

The article discusses how oceans are renowned for providing homes for thousands of species on Earth and are also essential for human life. Consequently, many organisms rely on the ocean for its capability of creating food and oxygen, however, over time, human activities have been negatively impacting the ocean and its wildlife. Additionally, the article lists various activities that have been impacting the ocean. The activities that negatively impact our envionment include overfishing of species, pollution and dumping, greenhouse gas emissions, and organic waste flows into oceans.

Its name comes from fishermen dubbing them the "right" whales to hunt centuries ago, because they were "docile and rich in oils." After being driven nearly to extinction in 1935, down to a population of only 60, the whales were protected by the Endangered Species Act and the marine Mammal Protection Act. However, once again their population is dropping, falling to about 430, the lowest its been in a decade. They are dying off due to entanglements with fishing rope, buoys, and other things. Scientists are doing the best they can to track those remaining and reduce the risk of their death. However, it seems like drastic action must be taken.

According to the article, tens of thousands of elephanfs are being killed each year. Many governments in Africa have tried to protect these elephants by laws and national parks, but not much as helped. The main problem is that poachers will go to great lengths to kill elephants for thier ivory. Humans have caused the elephant population to decrease by ivory consumption.The article takes this problem into greater depth.

This "island" was caused by the accumulation of plastic. This island posts many threats to sea animals. Sea animals mistake some of the plastic for food and ingest dangerous toxins that get passed down the food chain. Consequently, other animals, including us, that eat these animals also get the toxins. Plastic is effecting the whole world's health indirectly. This article explains the plastic island and its effects.

The article focuses on how the amount of greenhouse gases has risen since the begining of the industrial revolution and how since then, tempetures have been rising as well. According to the article, the amount of carbon dioxide has increased dramatically since the 1800's and that is most likely the main reason for the record high tempetures and the melting of the artic. Anthropogenic drivers or human impacts are responsible for about two thirds of recent atmospheric changes. This article provides multiple sources and statistics showing how humans are to blame for many recent changes on Earth.

The article said that recent studies on deep-sea pollution identified the bag, found in 1998 by a robotic submersible at the depth of 35,756 feet in the Mariana Trench, as the deepest known piece of plastic trash. Scientists say that this goes to show how troubling and worryingly plastic pollution has become after finding the bag in one the deepest and most remote environments. Researchers from Japan along with scientists from the United Nations Environment’s World conservation Monitoring Center found a disturbing amount of trash in deep-sea environments including the Japan Trench, the Mariana Trench, and many other deep-sea areas in the Indian, Pacific and Atlantic Ocean. In the database of plastic pollution, it was found that most trash in ocean environments are half plastic debris. Ivan Gutierrez

Sea turtles are hunted for their meat, eggs, and shells, and this has depleted sea turtle populations by large amounts in recent years. Many sea turtles are also caught in fishing nets, and thousands of sea turtles have been severely injured ot killed from being trapped in fishing nets. Sea turtles are also killed by plastic pollution in the ocean, and sea turtles, such as the leatherback, mistake plastic for jellyfish, which is a major part of their diet. Other types of pollution such as chemicals can contaminate the turtles food and the turtles, and the disease, fibropapillomas, has been found to be caused by water pollution.
       Turtles lay their eggs on a beach, and the baby turtles htch on the sand and go into the water. These beaches, however, could be blocked off by sea walls, or other forms of coastal armoring. These beaches could also be eroded away because of human activity, and humans' presence on beaches coul also stop turtles from laying their eggs. When the eggs do hatch, turtles follow the light of the moon to the ocean, burpt artificial lights from humans attract the baby turtles in the opposite direction, where they could be run over, or be trapped in storm drains. Invasive species introduced by humans also eat the baby turtles or the eggs. Climate change causes rising ocean levels, which can disrupt the beaches that turtles use for laying their eggs, and storms caused by climate change can negatively affect the turtles. Rising ocean temperatures can also disrupt the population balance of the sea turtles.

Monkeys and birds have an important role in distributing the seeds of trees. Because of the decrease in seed spreading, there is a loss of trees. The trees in the rainforest take in the carbon. The larger trees store more carbon. However, the seeds for the large trees can only be spread by the larger animals. With less trees from a combination of reduced seeds and deforestation, there has been an increase in carbon.

When humans have to expand into more wildlife, they will be cutting down more trees. The less trees, the less oxygen that will be made for all living animals.

Much of the food we eat is significantly dependent of pollination. Bees are starving because of industrial agriculture. Pesticides such as insecticides, herbicides, and fungicides used on agriculture are reaching bees most commonly through pollen and nectar. Although insecticides are not used to intentionally poison bees, they are a large cause in the decline. Humans can support bees and other pollinators by discontinuing to use bee-harming pesticides, enhancing the health, and farming with high biodiversity and without agrochemicals. -Sofia Suarez

It is the world's largest natural reef system. 25% of global reef systems have been destroyed by human activities and another 60% are getting threatened greatly. The first big issue that is killing the great barrier reef is poor water quality. This is a result of dredged material being dumped into the sea. Coral requires clean water so dumping  this caused the reef damage. Additionally, another issue was pollution. The pollution would get caught in water molecules and eventually make its way down to the ocean. This again causes harm to the reef. A third problem that humans created was global warming. Coral needs stable water temperatures so the water being heated by global warming caused damage to the coral polyps. Tourism and invasive species is another reason the Great Barrier Reef is dying. Tourism causes too much of a demand in natural products, causing the ecosystem to be disrupt and it is also disrupted when other non-native and invasive organisms are brought in by humans.
