Why do people continue to pollute?
Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth, too. Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. Oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. People should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution. What are toxic wastes? Toxic wastes are poisonous materials that are being dumped into the ocean. They harm many plants and animals in the ocean and have a huge impact on our health. Toxic waste is the most harmful form of pollution to sea life and humans. When toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. In the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. Toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. Farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans. Many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. One of the most harmful chemicals in the ocean is lead. Lead can cause many health problems. It can damage the brain, kidneys, and reproductive system. Lead can also cause birth defects for people. It has been shown to cause low IQ scores, slow growth, and hearing problems for small children. House and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead. Many things found in the ocean may cause seafood to be dangerous to human health. The effect on humans from contaminated seafood may include birth defects and nervous system damage. Medical waste found in the ocean is being tested to see if swimmers have a chance of developing Hepatitis or AIDS. Other waste has been known to cause viral and bacterial diseases. This type of pollution can be stopped by watching what pollution we are letting into the ocean. People are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean. Boating Pollution Prevention Tips Whenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life. Boating pollution is the pollution that comes from the boats engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. The engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. In order to make as little pollution as possible, what everyone can do to help is: Only turn a boat engine on all the way when you need to. Don't take your boat out into the water if you don't need to. Be sure to store and transport gasoline in places where there isn't any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air. Every year, buy new or cleaner marine engines for your boats. Garbage Dumping Garbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. Most of the waste that has been dumped into the ocean in the early 1990s is still there today. One main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. Rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. After that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animal�s neck, causing it to suffocate), and makes the water dirty. Waste water Waste water is a disposal problem that needs to be taken care of. Waste Water is run-off from rainwater and usually ends up in rivers, lakes, and oceans. In order to reduce the amount of waste water, we need to make sure that the water that ends up in the ocean is clean. We can do this by watching how much pollution we put into the ocean. Whenever even a small amount of pollution gets into the ocean, it damages the environment. A lot of people don�t realize that this same pollution is going into the ocean every day and all the small amounts add up to a major problem. To decrease the threat to public health, safety, and the environment, we need to watch how much waste water we produce. Other Sources of Pollution Pollution causes a lot of plant and animal deaths in the ocean. In addition to boat pollution, other things that cause water pollution are agriculture (like pesticide run-off), land clearing, and people that pollute the environment without thinking about what harm it can do to animals and humans. How are cars polluting the oceans? Cars pollute the ocean a lot. Whenever a car gets driven, you may have noticed a lot of smoke that is coming out from the back of the car. This smoke doesn't go directly into the ocean. It ends up being in acid rain. Acid rain is pollution mixed with regular rain, and when acid rain gets into the ocean, it pollutes the waters and kills many fish over a period of time. Cars are big pollution source. If pollution from cars cannot be stopped or at least cut down, then pretty soon the amount of fish and other creatures in the ocean will decrease. How is agriculture polluting the oceans?Chemical pesticides, chemical substances used to kill harmful animals or insects, and fertilizers, chemical or natural substances put on the land to make crops grow better, are another source of pollution. When it rains, the pesticides and fertilizers get taken off of the plants and end up in our oceans, killing ocean plants and animals. They are used by animal and agricultural farms, plantations, industries (especially illegal ones), and believe it or not, our very own gardens. A way to decrease the amount of pesticides and fertilizers polluting rivers, lakes, and oceans is by watching the amount of pesticide spray that you put on the plants in your garden. You can also buy organic products, which are grown with only natural pesticides and fertilizers. Households polluting the ocean Chemical detergents, batteries, plastics, and sewage are all produced by homes and everyday human activity. Every day humans create and use these things, and every day, people are creating a risk to the plants and animals that live in the oceans and lakes by doing things like driving without carpooling and making sure batteries are not leaking. Some ways that you can protect the oceans are by recycling plastics, disposing of batteries properly, using rechargeable batteries instead of regular batteries, using less water, carpooling, and recycling. The Ocean Zones From the shiny, clear sunlight zone to the dark, murky midnight zone, lie facts about the three different zones of the ocean. Even though the very bottom zone is about ninety percent of the ocean, more than ninety percent of the ocean�s sea life lives in the top zone, which is why it is important that we do not pollute our oceans. Sunlight Zone The sunlight zone is also called the Euphotic Zone. This zone is the top zone, and it is also the smallest. The sunlight zone is only about 600 feet deep, but ninety percent of the ocean�s sea life lives in the sunlight zone. This zone is home to a wide variety of marine life because plants can grow here. Plants can grow here because sunlight can get to the plants in this zone, so the plants can do photosynthesis and grow. Also, the water temperature is warmer than any other zone in the ocean. The sunlight can reach this zone and warm the ocean water, so it is warm enough for fish and other sea life. Sharks, tunas, mackerels, jellyfish, sea turtles, sea lions, seals, and stingrays are a few of the animals that live in the sunlight zone. Oil Pollution Pollution is major problem in the sunlight zone. The main kind of pollution that occurs in this zone is oil pollution. The two main causes of oil pollution in the ocean are big ships leaking oil or ships carrying oil crashing into things in the ocean. Global Warming Global warming is affecting many different parts of the ocean as well. It is causing the water to rise, and when it rises, it covers things such as low land islands with plants, animals, and even some people�s homes on them. This can hurt animals in the different layers of the ocean. One other way ocean layers are affected by global warming is that warm water, caused by global warming, is hurting and even killing algae which is what some fish in the sunlight zone eat. These fish would die because all of their food would be gone. When the fish die, it is a break in our food chain, which would lead to a big problem for all of the animals that rely on the algae-eating fish for their food. Twilight Zone The twilight zone is also called the Disphotic Zone. In depth, the twilight zone is about 2,400 feet, making it the second largest zone. As the water becomes deeper, the water pressure becomes higher. Almost no sunlight can reach this zone. Therefore, very few plants can grow here. The only animals that can live here are those that can adapt to very little sunlight, really cold temperatures, and very high pressure. The few animals that can live in the twilight zone are lantern fish, rat-talk fish, hatchet fish, viper fish, mid-water jellyfish, octopus, and squid. Many animals that live in the twilight zone have bodies that protect them from predators. The viper fish and the ratchet fish have fangs so they can easily protect themselves and help them eat their prey. Other fish are so thin that when a predator looks at them, they do not even see them! Some fish are colored red and black to blend in with their surroundings. Some squid and fish can use their bodies to make light with special organs in their bodies called photophores. These photophores give off a greenish colored light, which helps them see. Most fish in this zone don�t chase their prey. They wait for their pray to swim by. Then they snatch their prey and eat it. Toxic Pollution Some of the pollution that causes problems for the amazing creatures of the twilight zone are metals and toxic chemicals. These toxic chemicals settle in the sea, and eventually some of the fish eat these chemicals. Other fish eat these fish that ate the chemicals, and these fish, too, will eventually die because they are putting toxic pollution into their bodies. Midnight Zone The midnight zone is also called the Aphhotic Zone. Ninety percent of the ocean is the midnight zone. This zone happens to be the bottom zone, so it is completely dark. Very few creatures in the ocean live in the midnight zone because the water pressure is extreme and it is near freezing down that far. Some of the very few creatures that live down in this zone are angler fish, tripod fish, sea cucumbers, snipe eels, opossum shrimp, black swallower's, and the vampire squids. Because of the lack of plants at this depth, all of the creatures in this zone are predators. They survive by consuming bacteria which grows from the mineral-rich materials and hydrogen sulfide that are given off by underwater cracks in the earth�s crust. Since there is no light down in this zone, some fish do not even have eyes. Anoxic Water One problem caused by pollution that occurs in the midnight zone is called anoxic water. This means that there is no or hardily any dissolved oxygen in the water. When there is no dissolved oxygen, fish and other creatures can't breathe, and they will quickly die from a lack of oxygen. Some of the creatures that live at this depth might die or migrate to other parts of the ocean. If they do migrate, there is a possibility that there could become a problem in the food chain. It is very important that we address the issues that affect the ocean. Ninety percent of sea creatures live in the sunlight zone, which is the zone that is most affected by global warming and oil pollution. We must stop these problems because if we don't, we will hurt and maybe even kill our sea life.
* I would also like to add for the person that asked the question that I have been watching WHAT IS being done to try to curb pollution (if it's ever possible) and enjoyed a program on several different countries such as Australia and South Sea Islands, are now sinking some old ships so it gives the coral a chance to grow once again. Coral and many other sea life forms are close to becoming extinct in the next few more years unless humans get their heads together and start finding ways to replace what they take. * Oil spills. Pollution problems started when the factories were next to houses and the pollution was all over the place.
Sound pollution, also known as noise pollution, refers to excessive or disruptive noise that interferes with normal activities and can have negative effects on human health and the environment. Sources of sound pollution include traffic, industrial activities, construction, and recreational activities. Regulations and measures are in place to control and mitigate the impact of sound pollution.
Why is a volcanic eruption an example of natural pollution?
A volcanic eruption is an example of natural pollution because when a volcano erupts, volcanic ash and volcanic bombs are also erupted. The air produced suffocates animals and humans which are nearby. The eruptions also destroy houses, plants and trees.
"Pollution" refers to the presence of harmful or toxic substances in the environment, such as air, water, or soil. This contamination can come from various sources, including human activities like industrial processes, transportation, and waste disposal. It has negative effects on ecosystems, human health, and the overall well-being of the planet.
The heel is located at the back of the foot, below the ankle joint. It is the bottommost part of the foot that makes contact with the ground when walking or standing.
How does pollution and trash effect the growth of plants?
Air Pollution affects anything and everything around us. It can cause plants to die faster or too grow slowly and weak. Air pollution affects the oxygen that the plants breathe and so air pollution can cause a big part in a plant.
Air pollution can affect soil moisture levels. It's responsible for yo-yo moisture and temperature extremes. For example, too high temperatures can be accompanied by high rates of evaporation from the air, and evapotranspiration from the soil. Groundwater is recharged by moisture infiltrating into, and percolating through, the soil. Our supplies of below-ground water, ka groundwater, can run low. A plant's roots grow horizontally across, and vertically down, in response to soil moisture levels. If the levels aren't correct, then roots don't grow properly. Air pollution can affect salt levels in the soil. Too much salt in the soil is toxic to plants. It also causes the soil surface to compact, and crust over. Air pollution can affect nutrient levels in the soil. Healthy plants and soils need 16-17 nutrients. Incorrect amounts of any one nutrient throws the entire nutrient chain off. Air pollution tends to make large amounts of nitrogen and sulfur available to soil and water. Too much nitrogen can't be properly processed by the plant. It must be in soluble form, to be taken in. Too much nitrogen can burn the plant's roots. And it can contribute to changing soil pH. Soil pH can be acid, neutral, or alkaline. Most plants prefer a soil pH of 6.0-6.5. Below that range is acidic, above alkaline. Plants grow poorly, or not at all, in soil where the pH isn't correct. An incorrect soil pH can make nutrients available in the soil unavailable to plants. Sulfur's toxic in the soil, and to plants. Air pollution can affect photosynthesis. Photosynthesis needs sunlight. Smog can be so heavy that it affects the amount of sunlight reaching the earth's surface. Plants therefore don't get proper levels of sunlight. Photosynthesis can't take place properly. The plant doesn't build up enough carbohydrates. And it doesn't have enough energy to grow properly. Air pollution can affect temperatures. Side-effects of air pollution are global warming, and the heat island effect. Heat is trapped in the boundary layer of air that's closest to the earth's surface. The temperatures can be too high for plants to grow properly, or even survive.
How has population changed since 1850 from the effect of pollution?
The population has increased significantly since 1850 due to improved healthcare, sanitation, and technology. While pollution has had negative impacts on human health and the environment, it is just one of many factors influencing population growth. Efforts to reduce pollution can help mitigate its effects on population dynamics.
Why are sunrises and sunsets colorful?
During the middle of the day, the sun is for the most part above our heads. This means the sunlight goes right through the Earth's atmosphere. During sunrise and sunset, the sun is hitting the Earth and the Earth's atmosphere at an angle. When the light hits the atmosphere the light is broken up, appearing in the sky as many different colors. The similar thing happens when you shine a ray of light into a prism, it comes out as many different colors.
What are ocean bulges caused by?
Ocean bulges are caused by gravitational forces from the Moon and Sun. These forces create a slightly elevated area of water in certain parts of the ocean, resulting in bulges that lead to phenomena like tides.
To What affect does Acid rain have against fresh water?
Acid rain can lower the pH of water bodies, making them more acidic. This can harm freshwater ecosystems by affecting the health of aquatic plants and animals, disrupting the food chain, and damaging infrastructure like buildings and bridges near water bodies. It can also leach toxic metals from soils and release harmful aluminum into the water, further impacting aquatic life.
How much does air drying clothes save compared to drying them using a dryer?
Air drying clothes can save approximately $0.50 to $1.00 per load compared to using a dryer. This savings can vary depending on the energy efficiency of the dryer and the local cost of electricity. Over time, air drying clothes can lead to significant savings on your energy bill.

How do you build a French drain?
A French Drain is simply a gravel filled trench that crosses a property to remove water. The gravel provides porosity and the trench the directionality. With todays geotextile fabrics it would be possible to put a porous membrane across the op of the trench to keep it from silting up while providing the option for a sod grass cover.
Trees provide numerous benefits to humans, such as producing oxygen for us to breathe, absorbing carbon dioxide and other pollutants from the air, providing shade, lowering temperatures, reducing erosion, and supporting biodiversity by providing habitat for animals and insects. Additionally, trees can improve mental health and well-being by creating a calming and peaceful environment.
Why is diesel environmentally friendly?
Diesel is not considered environmentally friendly because it emits more pollutants like nitrogen oxides and particulate matter compared to gasoline. These emissions can contribute to air pollution and have negative impacts on human health and the environment.
.000380 is 380 millionths, ppm is to millionths what % is to hundredths. If you now move the decimal two places to the right to conver to a percentage, then 380 ppm is approximately .04%, and thus, CO2 makes up .04% of the air (which is what I assume this question is refering to)
Does air and water cause food contamination?
Sure it does buddy... because carbon emissions and burning fossil fuels contaminate air within our ecosystem and toxic waste such as plastic bags nearby river banks and lakes not only contaminate water but also kill numerous aquatic animals. Air and water together radiate different parts of our ecosystem and affect the growth of food. As a result, food contamination is likely to occur!
Chemical pollution refers to the introduction of harmful chemicals into the environment, which can come from sources like industrial waste, pesticides, and household products. These chemicals can negatively impact ecosystems, human health, and wildlife by contaminating soil, water, and air. Mitigating chemical pollution requires strict regulations, proper disposal methods, and adopting more sustainable practices.
How are microorganisms classified?
Living creatures are divided into two key groups: the prokaryotes, where the DNA in their cells is not enclosed in a membrane-bound nucleus and the eukaryotes where the cells do have their DNA enclosed in a nucleus and often contain other membrane-bound organelles as well. The eukaryotes include fungi, protozoa, algae, plants and all multicellular animals. Prokaryotes include bacteria and the mysterious archaebacteria which are prokaryotic in general structure but also share some characteristics with eukaryotes. Viruses are akaryotic because they are non-cellular.
How can acid rain affect trees such as pines and spruce?
Acid rain is a mixture of pollutants in the atmosphere as well as natural waste. When this falls, it can, over time, damage and corrode plants, rocks, and other living things. This can be seen in many old statues. Trees such as pines and spruce can be damaged by acid rain. It can eventually eat away roots and rot the inside of the trees. This can also be a problem because the most acidic rain falls the farthest north, where these trees are located.
What are the advantages and disadvantages of thermal pollution?
Advantages: None
Disadvantages: Thermal pollution can disrupt aquatic ecosystems by changing water temperatures, decreasing oxygen levels, and affecting the growth and reproduction of aquatic organisms. It can also impact water quality and harm aquatic life.
Why does a lettuce remain fresh in plastic bags?
Plastic bags help retain the moisture and reduce exposure to air, which can slow down the wilting process of lettuce. It also helps maintain a consistent temperature, preventing fluctuations that can lead to quicker spoilage.
Describe two effects that chemical pollution could have on aquatic animals?
Two effects that chemical pollution can have on aquatic animals are that the
animal could die from poisons. The second effect that chemical pollution has on
aquatic animals is that if the chemicals don't poison them the animals have
problems reproducing.
The traits of gas are no definite volume, shape and mass. Gases are also easy to compress and can occupy far more spaces than solids and liquids from which they form.
What is the oxygen demand for a human?
In Rest a normal human (65 Kgs Body Weight) will need 250ml/min. of oxygen.
Depending on the activity the body might consume 15 times as much oxygen as it needs in rest.
