Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction. 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 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. If there is another water crisis it will affect many things. Water crises are bad in many ways so don’t pollute the
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. Mining will pollute the water and let out toxins that can kill species and communities near by.
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.
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. The colonist thought the waste would wash up but instead it “tended to fester rather than flush away” according to document A written by Denni Blanton of William and Mary College. They would later drink the water and they would get ill and eventually die from diseases.
“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. There are millions of dolphins out in the oceans and they are declining fast because people couldn’t take another 12 steps to get to the trash cans that are all over the place in cities.
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.
Marine mammals such as seals are being found entangled in plastic fishnets and several drown. 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?”
