Question

1.
Answer question numbers 1-4 on the basis of your understanding of the following
paragraph and the related studied concepts.
Wherever we look, we find plastics-be it a food packet, a toy, storage packing, any furniture
or an electronic item. According to UN estimates, every year the world uses 500 billion
plastic bags and half of this plastic is single-use plastic such as plastic bags, straws, cups,
plates and bottles. Plastic is currently the biggest environmental concern. Plastic waste takes
a lot of time to decompose naturally. It is harmful for animals who might eat it and can cause
severe air pollution on burning. In oceans, pollution is mainly caused due to plastic wastes.
Each year, at least eight million tonnes of plastic wastes are released into the oceans which
means a full garbage truck every minute. This is damaging the marine life and also
threatening human health.
1.1 Why has there been huge hue and cry against the use of single-use plastics? [1]
1.2 The pH of ocean water as measured using pH paper is found to be 5. What does this
pH tell us about the ocean water? [1]
1.3 Based on the data shown in the graph that follows, which industrial sector produces
the most plastic waste? Suggest the alternative that can be used in place of plastic in
this sector?
1.4 Expand the five R's that help in reducing plastic wastes.
