Plastic Pollution is a very recent man made
catastrophe, but it is persistent, pervasive and pernicious. Once it gets
into the water, it is causing harm to the environment and ecosystems,
damaging coastal economies and ultimately affecting human health.
Entanglement in plastic debris has been
responsible for the deaths of many marine organisms, such as fish, seals,
turtles, and birds. These animals get caught in the debris and end up
suffocating or drowning. Because they are unable to untangle themselves, they
also die from starvation or from their inability to escape predators.
I really liked your approach in formulating the
question, I would add data on the size of the damage caused to the environment
and how it influenced the amount of fish drastically.
For example: "The plastic pollution harms an estimated 100,000 sea turtles and marine
mammals and 1,000,000 sea creatures each year".

Water
pollution is a wide subject, and a very important one. I like the way you represented
the different kinds of water pollution by photos. The photos emphasize the relation
to everyday life, and that pollution reduction is in our hands. I think
that the connection between the video of fish breathing and the water pollution
by plastic bags is not a strong one. The short video showing plastic bag interrupting
the water flow in the sink was a very good demonstration of what can happen in
water or sewerage pipes. I would have loved to read a short story (maybe a
short article from the papers or an invented one) before the question. It could
have helped "connecting" me (or a pupil) to the question.
Hanni's
geographic point is very good, because she gives her opinion about cleaning the
beach, and connects it directly to the plastic bags on shore and in the water. I
liked her showing a personal point of view.
The
point of Palmachim beach is strongly connected to water pollution, but not to
the subject presented in the question. If the question relates to plastic bags pollution,
maybe a specific data about the amount of animals effected by, or a story of
saving a turtle ect could make a stronger connection.
The
point of the Shafdan is giving a lot of information about wastewater treatment,
and also refers to polluting the sea, but (again) doesn't give a hint /
information / story / explanation of the specific subject in the question.
You
tube videos showing the damage of plastic bags to nature:
I can see your point. Fish respiration itself doesn't demonstrate pollution harm. Nevertheless fish respiration understanding is vital to understand the point that fish do breath although they live in water. It's not an obvious point to know that fishes breath, especially for children, so we would like to emphasize it.
first I`d like to say how important is the subject you choose,
The idea of dividing the types of pollution and the effect of each type of pollution on water ecology is hellping to understand the pollution affects from the time point of view and in terms of how it impacts.
It was very important to present the ways to reduce each type of pollution, you could specify in a few words the ways in which we can cause a reduction in pollution directly and even reducing pollution indirectly as using green energy, what will reduce the reliance on oil and thereby reduce the need for transportation of oil and consequently the pollution caused by leakage of oil from ships.
The connection between the question and geographic location is partly, because you did not talked about any direct effect of pollution on fish populations and marine life.
The geographic location is good, since it is certainly relevant to the idea of arine populations.
The information contributes to the understanding, esspecialy Tzahi`s which talks about Palmahim beach pollution.
I wanted to see more information about the effects of changes in population size and changes caused by the pollution like smaller fish and so on.
I would like to see improvement is an example of the effect on the population size of a particular type of fish over a period of time and see some population living in the sea are at risk of extinction due to the effects of pollution.
There are definitely many types of water pollution and many aspects which can be referred to: here we chose to emphasize on plastic garbage, thrown by people, which causes to sea creatures death (choking).
The plastic pollution is an important and
interesting issue, that affects our lives. Thus it is critical to further study
this topic and to understand its future implications.
Since the plastic pollution can cause a lot of damage, we
have to seek for possible solutions, which can improve the situation and reduce
the pollution negative effects.
Also we can explore deeply a specific plastic pollution
event by trying to investigate the mechanisms and the results of such event,
and then rating the findings statistically
in order to understand the event in a more accurate way.
