The dark sides of pollution
We all know that to keep our city clean & safe we need to maintain it with less pollution. Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Industrial waste pollution, vehicle emission pollution, building pollution are all we know about.
Major forms of pollution include: Air pollution, light pollution, littering, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, water pollution.
Here in this blog, I want to touch the topics of few types of pollution which go unnoticed, but is still harmful in every way! Let's try to make a joint effort as a team to understand & educate ourselves & others about the dark side of pollution & how we can bring a change. Our city can use this help.
Right now you are reading this blog on an electronic device. Do you ever think of where it will end up when you are done with it? Many devices contain toxic materials & should be recycled very carefully. Sadly, lots end up in landfills, but, even if you are diligent and give your electronic waste, or e-waste, to a recycler, that’s no guarantee about what happens next. American recyclers often ship it overseas, frequently to countries in Southern Asia. There, workers take apart toxic materials by hand, often without proper safety measures. For example LCD monitors have mercury in it, which is poisonous to humans, animals & environment when broken down open. E-waste exporting is not ethical, but is still a dominant part of our society.
If the recyclers handle the work responsibility & shred the electronics wisely, it makes a whole lot of difference but, not all do that.
For a lot of us, the effects of e-waste can seem so far away that they’re hard to grasp. But the way our electronics are recycled matters. Federal legislation to reform e-waste exporting has been on the table for years but keeps slipping away.
Solution: Try to reuse your electronics, Many of the materials used in making the products can be recovered & reused. Do not buy unwanted stuff. Sell or donate your old electronics to charity or non profit that would be happy to take it off your hands. Locate a recycler & Research before the recycling place where you are donating the electronics to.
Did you know that everyday we are surrounded by invisible electromagnetic radiation from microwaves, computers, televisions, power lines wiring in the building to Cellphones. They produce electromagnetic radiation.
These days, every kid wants to have a cellphone, or more likely already has access to one. Their phone or their parents, it will still be a phone . But cellphones give radiation and if exposed to too much radiation at such an early age they get five times as much radiation than adults do. The reason is it’s easier for radiation to reach a kids brain because of the kids skull is thinner than the adult skull. When radiation goes through the body, it can kill cells & if those cells don’t heal they might become cancerous.
Protect yourself from the radiation pollution, limit the use of cell phones. Make a change!
We all know how beautiful a star lit sky looks like when we go out on a camping trip. Unfortunately we cannot see this beautiful sky from our backyards. We light up the skylights so much that pollution light trespasses by over-illumination and astronomical interference.
The ever-widening use of artificial lights is making the nighttime Earth glow increasingly brighter. The artificial night glow can affect wildlife like migrating birds and keeps people from connecting to the stars. What's more, all that wasted light sent out into space is effectively wasted money. Some have suggested that energy-savings from LEDs will reduce the cost of lighting. But we know that "as light gets cheaper, we use more of it, nearly proportionately to the rate at which it's getting cheaper,"
Solution: Try limiting use of lights everywhere around the house. Turn the lights off before getting out of an empty room. We don't need overhead lights in the front or back yard. These overhead lights traps the insects & eventually those insects die due to the heat. Use the dim curb lighting instead.
Reduce, Reuse, Recycle
By contrast proper recycling is more expensive but it’s doable. So none of this really have to happen. Meanwhile the damage that’s happening is real. Pollution, it does harm people. Nobody quantifies it, and it’s really hard to quantify how many casualties happen prematurely, the data supports the fact that these pollutants do cause death and disease. Lets make our city, Boomtown, pollution free as much as possible.
