What are Micro-Plastics?

Micro-plastics have not been defined in particular. They are just tiny particles that result from the disintegration of bigger plastic materials. However, most researchers say that any plastic smaller than 5 millimetres in size is a micro-plastic. Hence, these are really, really teeny-tiny!

A Trash Course!

Do we ever stop to think where all the trash that we produce goes? Most of it heads to a dumpsite – yes, those mountains of waste that you might have seen on one of your trips around the city. Let's dig into this subject a bit, shall we?

**********************************

A huge dark mountain is looming up amidst houses and buildings, with a flock of crows and eagles circling over it. As one goes closer, you can see people on it, scouring for things they can re-sell, while scrawny-looking dogs fight to find something to eat. Trucks carrying loads of trash trudge up the mountain.

AQI? What is That?...

We keep reading or hearing about air pollution and its deadly effect on our health and environment. More recently, we have also been hearing this new abbreviation being mentioned quite regularly: AQI – or Air Quality Index.
