how is pollution harming animals

How does air pollution affect animals?

In short, air pollution affects animals both directly and indirectly and the amount it affects a certain animal will vary greatly depending on a number of factors. Direct effects include: 1 Inhalation of gases and particles in the air 2 Ingestion of particles in food or water 3 Absorption of gases through the skin

Which animal is most at risk of air pollution?

Arguably even more at risk to the direct effects of air pollution are birds. Unlike pets, they don’t spend time indoors and are often resident in our cities where air pollution levels are high.

What is an air pollutant?

A substance that causes air pollution is known as an air pollutant and is defined as:

What is the name of the air pollutant released by refrigerators and aerosols?

Chlorofluorocarbons (CFCs) are an air pollutant released by refrigerators and aerosols. These are broken down in the atmosphere to form, among other things, chlorine. The chlorine reacts with the ozone and this converts it to oxygen which no longer provides the protection from those UVB rays.

What causes acidification in the ocean?

Ocean acidification occurs when the increasing amount of CO 2 from air pollution is absorbed by the oceans. The absorption of CO 2 changes the pH of the seawater i.e makes it more acidic.

What is secondary pollution?

Any substance directly emitted and instantly having adverse effects are primary pollutants. Secondary pollutants are caused by these primary pollutants reacting with another substance causing a new pollutant to form.

What are indirect effects of air pollution?

Indirect effects include: Climate change. Ocean acidification. Acid rain. Ozone layer depletion. As you can see there are plenty of potential effects of air pollution on animals. Some of these are quite well understood and some are not. In this article, I will briefly try and summarise what we know.

Why are animals vulnerable to air pollution?

Animals are especially vulnerable because they have respiratory systems that are much more sensitive than humans. The effects of air pollution on animals include lung damage, heart problems, inflammation, and cancer. Animals may also suffer from the effects of pesticides sprayed on crops or lawns.

What are the effects of air pollution on animals?

Some effects that air pollutants have on animals are cancerous cells, pulmonary edema (or fluid in the lungs), acute myocardial infarction (heart attack), and cardiac arrhythmia (abnormal heartbeat).

How do pesticides affect animals?

The effects of pesticides on animals may include difficulty breathing, lethargy, muscle spasms, vomiting, or loss of coordination. Animals that live close to the ground have a much higher risk for inhaling air pollutants than other species.

How does pollution affect the immune system?

Pollution affects the immune system as well. This stresses out your body’s natural defenses, which leave you more vulnerable to infections. Polluted environments also increase the prevalence of allergies for people who are allergic to it already while making those without prior sensitivities even more susceptible.

How does air pollution affect humans?

Air pollution also affects their ability to reproduce, so there’s an increased risk of infertility and congenital disabilities. Pollution can also cause hormonal changes in plants which, if they’re eaten by animals higher up the food chain, such as cows or chickens, could affect human health.

Why do animals' eyes get dry?

In places of high air pollution, the animals’ eyes may become dry or irritated because there is less oxygen in the air to help them breathe easier. The animals may find themselves with more respiratory diseases as their lungs work harder to take in clean air.

How can we reduce air pollution?

One way for us to help reduce threats posed by air pollution is simply getting more exercise! Researchers found out that walking just six minutes per day decreases your risk of death by 15 percent. The effects of air pollution on animals can be seen in many ways.

How does water pollution kill animals?

More Than a Million Sea Birds and Mammals Are Killed Each Year By Ingestion of Plastic. Around 100 million tons of plastic is produced every year, of which 10 percent ends up in the sea.

How does fertilizer affect the environment?

Chemical runoff from farms is leaching into nearby streams, waterways and groundwater, killing thousands of insects and fish. The presence of fertilizers in the water alters nutrient systems, resulting in explosive growths of algae that produce harmful toxins and deplete the water of oxygen, and as a result little or no marine life can exist. Scientists have recorded an estimated 400 such dead zones around the world.

What happens to the debris in the ocean?

Once in the water, the debris accumulates in large patches, travels with currents and washes up onshore. This litter is frequently consumed — often with fatal effects — by marine mammals, fish and birds who mistake it for food.

Why are cruise ships toxic?

Due to lax laws, cruise ships have been operating with little to no environmental regulations, and as a result have caused a great deal of damage to sensitive marine life. Current regulations allow cruise ships to legally dump untreated sewage and other waste once the ships are three miles from shore. This toxic waste is discharged directly into the ocean and contains bacteria, pathogens, medical waste, oils, detergents, heavy metals and other harmful substances, all of which are putting aquatic life at risk.

What are the effects of gas and oil exploration?

The deafening noise of gas and oil explorations are so loud that they are causing devastating effects to the sea life residing in our world’s oceans such as mass strandings, reckless diving, the inability to find food and chronic stress.

Is pollution physical or chemical?

Pollution is not always physical. Sound waves from ships, sonar devices and oil rigs can travel for miles disrupting migration, communication, hunting and reproduction patterns of many marine animals.

How much of the ocean pollution is due to land based activities?

Over 80% of the sources of marine pollution are due to land-based activities. Every day, government, big multinational companies or organizations are announcing or inventing some ways to tackle the problem which is mainly plastics. The oceans are cluttered with plastic, chemicals, oils and many more toxic chemicals.

What percentage of marine pollution is caused by oil spills?

10% of marine pollution via oil is caused due to an accidental spill of oil by the ships.

How does oil affect the ocean?

A million gallons of oil are dumped into the ocean each year. There are also oil spills from drilling in the offshore areas that enter into the oceans due to runoff by the rivers and lakes. According to NOAA (National Oceanic and Atmospheric Administration), there are 4 major sources of oil spill enhancing marine pollution. They are: 1 37% of the oil leakage is caused due to oil consumption in the storage and production of industrial and municipal wastes, and runoff from the urban areas. 2 3% of the oil pollution is caused due to the extraction of oil in the offshore mines. 3 The natural oil from the bottom of the sea beds enters the oceans and caused almost 45% of the pollution. 4 10% of marine pollution via oil is caused due to an accidental spill of oil by the ships.

Why do toxic materials end up in the ocean?

Due to the water-soluble property, toxic materials often end up in the oceans or microlayer of the sea surface. According to a report by WWF (World Wide Fund for Nature), 8% of marine pollution is due to toxic materials that originate from the land.

Why do sea turtles eat plastic bags?

Due to the blocked digestive system , they suffer and die a painful death. Sea turtles consume plastic bags as they think of them as jellyfish which is their food. Various forms of plastics are the causes of starvation, entanglement, strangulation, and drowning of different marine lives.

Why do fish die in plastic fishing nets?

Many aquatic animals get entangled in the old plastic fishing nets and die due to choking and suffocation. Microbeads of plastic are consumed by the turtles, fish, and birds that clogged their digestive system. Due to the blocked digestive system, they suffer and die a painful death.

How much of the debris found inside the aquatic animals is man made?

55 to 56% of the debris found inside the aquatic animals is man-made.

How does animal waste affect water quality?

Animal waste from factory farming contributes to water pollutionwhen the large, open-air lagoons that house wastewater from the farms leak and contaminate local water supplies, or when runoff from the farms makes its way into nearby lakes and waterways.

How does water pollution affect the ecosystem?

Water pollution affects all species, even the tiniest of microorganisms, and threatens the survival of our ecosystems. And since natural bodies of water are usually connected to other water sources,  when one becomes contaminated, so do the others. Advertisement.

What are the causes of water pollution?

It’s a well-known fact that we have a water pollution problem. Pesticides, fertilizers, and animal waste from the agriculture industry are contaminating our lakes, waterways, and oceans.

Why do algal blooms occur?

Pollution due to excess nutrients in freshwater or saltwater also results in algal blooms, which are a thick sludge or discoloring that covers the surface of a body of water. These toxic blooms pose a threatby depriving the water of oxygen, which is essential to the survival of aquatic species.

What are the most harmful pollutants?

Mercury is one of the most harmful pollutants faced by fish and wildlife. Mercury is a naturally occurring, toxic heavy metal. However, human activity has significantly increased mercury levels in the environment over the past several centuries. Coal-fired power plants burn coal and release mercury into the atmosphere as a byproduct. Coal-fired power plants are the single largest source of mercury contamination in the United States, responsible for approximately 50 percent of human-caused mercury emissions. Other sources include waste incinerators that burn mercury- containing products and chlorine manufacturers. However, unlike these sources, power plants haven't had to limit their mercury pollution.

What are the byproducts of pollution?

Pollution | National Wildlife Federation. Every day the byproducts of our daily lives—sewage, exhaust, trash, agricultural and lawn chemicals, industrial and powerplant emissions , and more—make their way via the air and water into the natural environment and become pollutants. As big as our planet is, it's not big enough to dilute or absorb all ...

What are the sources of nutrient pollution in the ocean?

Key sources of nutrient pollution in our waters are agricultural sources, like inorganic fertilizers and manure runoff, and point sources, particularly wastewater treatment plants. Studies have shown reducing nutrient inputs to waters is important to reducing HAB occurrences.

What are harmful algae blooms?

Harmful Algae Blooms. Harmful algal blooms (HABs) are becoming an increasingly common occurrence across the United States and around the world. Blooms (large numbers or colonies) of the algae or related organisms produce one or more toxins that can be dangerous to fish, wildlife, pets, and livestock.

What are the non point source pollutants?

However there are many non-point source pollutants—coming from many diffuse sources—that are still regularly released into the environment. These chemicals and nutrients continue to wreak havoc on wildlife and ecosystems. Excess Nutrients: Phosphorus and nitrogen are limiting factors for plants.

What are persistent organic pollutants?

Persistent Organic Pollutants: Persistent organic pollutants are synthetic toxic chemicals —such as PCBs, DDT, and dioxins—that are easily carried by wind or water and can persist in the environment for a long time. They can accumulate in the tissues of plants, animals, and people, and pass from one species to another through the food chain. As the chemicals move up the food chain, they become more concentrated (a process known as "biomagnification"). Populations of raptors, such as the bald eagle, declined dramatically in the 1950s and 60s because of DDT, which thinned the shells of their eggs so they were not able to produce young. DDT is now banned in the United States.

How does mercury affect fish?

Mammals have impaired motor skills that affect their ability to hunt and find food. In addition, some evidence indicates elevated mercury levels can adversely affect species' immune systems .

Why are dogs more affected by environmental pollution than healthy animals?

Dogs with a history of respiratory conditions or heart problems are more affected by environmental pollution than healthy animals.

What are the problems dogs face in cities?

Noise pollution is another problem that affects dogs that live in large cities. This can also cause fear, anxiety, and stress.

Why does my dog sniff the ground?

This happens because polluting particles, such as lead, usually accumulate on the ground that your dog sniffs during walks. And the damage is even more serious when we’re talking about homeless dogs.

Is pollution a problem in big cities?
