Question:

Pollution is one of the primary ways in which we people have caused drastic modifications of wildlife habitat.

It was widely assumed that no matter how much trash and chemicals are dumped into the sea water or into the ocean, the effects would be negligible. There was even a catchphrase: "The solution to pollution is dilution."

The dumping of industrial, nuclear and other waste into oceans was legal until the early 1970's. Nowadays, many national laws, as well as international protocols, forbid dumping of harmful materials into the sea and ocean.

One of the most harmful materials which cause sea pollution is plastic. Its production increases all the time, since we all find it comfortable using them.

Sadly, many of these single-use bags and bottle corks find their way to the sea, where they are often mistaken for food by sea turtles, dolphins, whales and sea birds.

Plastic garbage can reach the sea also when it's far away from it:

People still



In the following assignment you'll help us to investigate sea pollution as a function of presence of people in the sea shore and their habbits to use plastic bags:

Please choose one of the following 2 options:


1) If you live near the sea, we'll appreciate if you use your camera to take 1 - 4 pictures, or a video, of the shore where people are spending. (No need to take pictures of people, only of the sand and the sea). Please go to a short walk of about 500 meters and refer to the following parameters:

1. Were there a lot of people around?

2. Was the shore clean? Were there tar spots/ plastic bags?

3. Did people you've seen helped to keep the shore clean?

4. Were people you saw using plastic bags?


2) If you don't live near the sea, please take 1-4 pictures or a short movie near the place where you live: use google maps to measure 500 meter path from your home and go for a short walk to refer to the following parameters:

1. Were there a lot of people around?

2. Was the street clean? Were there plastic bags?

3. What was the distance from your home and from the shopping center?

4. Were people you saw using plastic bags?


Thanks for providing the information!
