The Causes and Effects of Pollution

The Causes and Effects of Pollution

There is a large amount of pollution on our planet. It is produced by lots of things such as cars, trucks, factories, wildfires and even humans.


Air Pollution

The result in all of this pollution in the air is that we humans are inhaling the chemicals and toxins and it is making us sick because some of these pollutants are poisonous and they can cause serious harm. The poisonous gases in the air are some such as hydrogen chloride, benzene, or elements such as cadmium, mercury, and chromium. This is even more of a danger because it also causes global warming. All of the carbon dioxide and other harmful gases damage the ozone layer in our atmosphere and all of the radiation and heatwaves are entering our planet and harming us. One of the results of global warming is that the ice in the north and south pole is melting and all of the animals that live there will lose their home.

So we need to do something to reduce this threat. One thing that you can do to help is that you could ride a bike or walk instead of using cars and trucks. Also, try to be safe and careful when you are camping or doing outdoor activities in the forest or a location with a lot of plants surrounding it. Something else that we can try to do is to limit the use of factories and other things that produce gases that harm our environment.


Ocean Pollution

Ocean pollution is when people throw trash in the ocean, water or on the streets. When people throw away trash on the street, it goes down the storm drain and into the ocean. ocean pollution can cause many marine animals to die.

Thee plastic rings that hold soda cans can go into the animal’s neck and choke the animal or they could think that it is food and then they eat it and choke. Also, the bad and rotten food that we throw in the streets on into the ocean can be poisonous or fatal to the animal, so when they eat it, they could die of food poisoning

Also, when we throw away our trash in any other place but the trash can, it goes into the ocean and it makes it polluted and dangerous for people to drink and swim in. The polluted water is damaging the ecosystem. It blocks the sunlight and it makes the water dark and damp, also, when that happens, it does not let the producers in the water, like seaweed, seagrass, and algae photosynthesize and make oxygen for the marine animals to breath in. This is damaging the coral reefs in our oceans and making them lose their color and beauty. When they get polluted and they turn dark and lifeless.



Land Pollution 

Land pollution is when people throw away trash on the streets, parks, and other public places, which leads it to be thrown into the ocean. Also, it can lead it to the landfill where it is burned which causes more air pollution. All of this pollution is making our planet unhealthy.

All of the trash that we don’t throw away stays there until someone picks it up. If people keep on throwing away trash and not picking it up, our planet will become filthy and it will be covered in trash and filth. The entire world will be dirty and polluted.


Light Pollution

Light pollution happens when the night sky brightens and it is caused by street lights and other man-made sources. It has a disruptive effect on natural cycles and inhibits the observation of stars and planets. For example, all of the artificial lights in our planet can disrupt the seasonal cycle of trees, causing them to look different when they are not supposed to, like in spring, the leaves will be red, orange, yellow, and brown and they will be scattered all over the floor. Also, “in an average year in the U.S., outdoor lighting uses some 120 terawatt-hours of energy, mostly to illuminate streets and parking lots. That’s enough energy to meet New York City’s total electricity needs for 2 years. Unfortunately, up to 50 percent of that light is wasted. That adds up to $3.3 billion and the release of 21 million tons of CO2 per year! To offset all that CO2, we’d have to plant 875 million trees annually” (

With all of this pollution, we won’t be able to observe the stars and other planets. For example, if there is too much light, even at night, it will be too obscured, you will not be able to observe the night sky and see all of the marvelous things that are in outer space.


Also, light pollution kills millions of birds a year. Artificial lights can disrupt the migratory schedules of birds causing them to leave too early or too late in the season, missing ideal conditions for nesting. Birds that navigate by moonlight and starlight can wander off course. Millions die every year by colliding into illuminated buildings. Every year, the Fatal Light Awareness Program (FLAP) tries to raise public awareness for this.

Fun Fact: The sky glow of Los Angeles is visible from an airplane 200 miles away. 


To reduce air pollution, we can ride bikes, walk, and use electric cars more often instead of using cars. We can reduce the time that we use factories so that we do not use them when we do not need them. We can turn off our lights, air conditioning or electricity when we are not using them. Also, we can throw away our trash or even better, we can use recyclable things to reduce the amount of trash that is burned and thrown away.
