The animals hear sonar devices, sound waves from boats, and oil rigs that are really loud. This can cause the animals to have mass strandings, reckless diving, being unable to find food, and have chronic stress. Abigail goes on to inform us that cruise ships have also done a great deal of damage to the ocean life. Since there are poor laws in place regarding the way they dispose of the waste from the ships, it all goes into the ocean untreated with many harmful bacteria, pathogens, and other stuff we dispose of. The law tells them that they can legally dump the waste 3 miles away from the shore.
“The toxic algae bloom in Lake Erie that provoked last weekend 's tap water ban in Toledo, Ohio—where nearly half a million people were told not to use water for drinking, cooking, or bathing—is a preview of similar problems to come around the world, scientists say, thanks in part to climate change.” (Jane Lee). There could be many fish killed if there is another algae bloom. The water crisis is caused by warm water and runoff.
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
Mining the hydrothermal vents could make it so that some very bad things could happen to our earth. Mining is very bad idea until we finish all of the studies about hydrothermal vents because very bad things could happen to fish and the communities nearby the mining. First, The vents are used as homes for species. Mining could wipe out all of the yet to be discovered species.
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years.
The three primary reasons why the early colonists in Jamestown died was due to environmental problems, war and continuous droughts. Many colonists died because of the environment. The main reason the enviroment killed them was because of the contamination of the water, and tides. The contamination of the water happened when they dumped their waste into the river.
“An average person takes about 12 steps before they litter. ”(“Eye-Opening Statistics”). This is a shocking statistic. An average person shouldn’t even litter, littering harms the environment in many ways. It harms the oceans, each year about 300,000 dolphins die because the government throws the trash littered into the oceans.
The wells the colonists made were risky because of the high chance of salt water intrusion. Also, you have to remember the human waste festering in the water, and even when the tides rush in it doesn’t move the waste out. Therefore, there could be diseases in the water, which could kill the colonists. Remember that the people in the 1600s could not filter water like we can so the colonists (because of the lack of freshwater) had to drink the contaminated water, which could lead to death. This is why I believe that one of the major factors of the colonists deaths is the environment.
This played a key part in the reasons for colonist dying. The drinking water was brackish which means it was very salty so people got sick as they drank it. On top of that, the river was also dirty. This is because the tides from the Chesapeake Bay backed up the water, causing the garbage that was dumped in the river to do nothing but float back to the settlement. Another problem was drought.
It is tragic that the oceans have large amounts of plastic contamination which is causing problems with marine life and beach birds. It is discovered that these animals are mistaking small plastic debris for food, Susan Casey in her article, “Our Oceans Are Turning Into Plastic…Are You?”
Starting with the food chain in Chesapeake bay, the plants and algae play the basis role in food chain. They make their own food by sunlight. These plants and algae are bay grass and free floating algae. The plants and algae not only feeds all other organisms in the water but also gives homes and shelter for other organisms. Frogs lay their eggs on the bay grass, giving the tadpoles a home.
The Invisible Sea is the Salton Sea. The Salton Sea has been slowly drying up. Now the lakebed that has formed because of this is polluting the air with harmful toxins. Winds then spread these toxins and people inhale them. This increases the risk of cancer, cardiovascular disease, asthma, and chronic respiratory disease.
As humans expand they are producing more waste and need a place for it to go. In some countries, people just pump the waste into the water, as a result it is harming the manatees. The waste that humans are pumping into the ocean is causing toxic algae which the manatee eats and it makes the sick or could kill them. The waste from humans hurts the manatee also by
These companies release toxic fumes into the air we breathe, and in some cases dump toxic waste into lakes and rivers directly affecting the environment, aiding to poor air quality and toxic water. According to the EPA Sumner County ranks between the 80-90% bracket for being the dirtiest/worst for having water sources with impaired or threatened uses. With the high levels of metals in the environment it is an environmental injustice. Not only are humans affected by toxic pollutants, these chemicals also pollute the homes of many fish and birds that claim home to the lakes and rivers of Sumner County. We have to make sure our fish and birds live in clean water so they can promote diversity in the
The medical centers were either destroyed or in utter disarray and power was lost for quite a while. Not only was the amount of people displaced from their homes great but, the concern that people were going to get sick because of contaminated food or water also weighed heavily on people 's minds. All of the health concerns for New Orleans came from the amount of flood water because there was so much of it that it was an optimal breeding ground for mosquitoes and the water covered everything making nothing truly safe.
