Many facts about air pollution.
Many facts about air pollution.
Air pollution facts: I've got them! Earth science magazines have been cramming air quality issues down our throats for a while. It's for good reason, too. We've actually had some success.
There are more cars on the road than ever, but some air pollution solutions have been implemented.
As a result, we're actually breathing cleaner air now than we were forty years ago. You might be surprised by these air pollution facts. Let's start with the good news about cars.
A new car emits one-twentieth as much pollution as a mid-sized car from the sixties. We got rid of lead from gasoline, so this improvement is possible. Since the 1970s, atmospheric lead content has dropped 96 percent.
It's predicted that the cars of the future will create even less pollution, improving air quality everywhere. Especially with the increasing number of cars on the road, there is a growing concern about the negative impact of vehicles on the environment.
Several car companies are investing heavily in developing and promoting electric and hybrid cars, which produce much less emissions than traditional gasoline or diesel cars. Alternative fuels like hydrogen fuel cells and biofuels are also being explored.
Aside from these developments, there are also efforts to make internal combustion engines more efficient, which can reduce emissions even more. In addition, innovations like self-driving cars could lead to more efficient use of vehicles, reducing the number of cars on the road and reducing pollution.
It's possible to avoid air pollution. Air quality dispersion modelling helps industrial operators figure out how their operations affect the environment. Then they can design cleaner plants using the data. I can do air quality modeling for you if you're in this situation. You can use air quality modeling to figure out how your industry affects your neighbors' air quality and how to improve it. Take a look.
Here's some history: Cities are getting less polluted. I'll give you an example: Mexico City has had some of the most polluted air in the world and recently exceeded U.S. pollution standards on a regular basis. As far back as the 1950s, southern California air was more polluted than Mexico City air at its worst.
Besides Los Angeles, San Diego, and San Francisco, other cities have seen cleaner air in recent decades. There's still a big difference between Canada, the US, and Europe. Air quality in the US has improved significantly in the last few decades thanks to stricter regulations, better technology, and more efforts to reduce pollution.
It's amazing how many North Americans don't even know about the progress made against ground-level air pollution. Almost two thirds of people polled said they thought our air was getting worse.
Ground-level air pollution doesn't include gases like carbon dioxide that have been associated with global warming or ozone depletion caused by chemicals like chlorofluorocarbons that deplete the ozone layer. In spite of that, it still has a huge impact on human health and the environment. Health problems like respiratory illnesses and heart disease can be caused by ground-level air pollution. It can also damage crops, trees, and other plants.
Pollutants released directly into the air from factories, cars, and power plants are called ground-level air pollution. Air pollution at ground level is mostly smog and particulate matter, which are caused by burning fossil fuels like coal and oil. Meanwhile, ground-level air pollution can cause global warming and ozone depletion. That's another reason air quality dispersion modelling is such a valuable tool for informing future decisions.
Even though air pollution has been reduced a lot, we still have a long way to go. Additional facts about reducing our own impact on the environment.
One thing you can do is use your car's air conditioner less. Also, you can reduce the weight in your car so it runs better. Clearly, cars of the future will focus on reducing pollution and improving air quality, and we can expect many exciting innovations in the automotive industry in the coming years. Until then, reducing your driving might help.
Vote with your wallet, and at the polls for more eco-friendly options. Hope you get it.
