Which are the ways through which each one of us may reduce plastic pollution?

  1. Use silverware instead of plactic utensils, keep a set at the office, bring a set on a picnic or to the beach

  2. Download your music instead of buying CDs

  3. Seek out items that are not made of plastic

  4. All of these

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The best thing we can do to protect our waterways is try to keep as much plastic as possible out of the waste stream in the first place. There are many small ways you can have a big impact.

1. Wean yourself off disposable plastics.
Ninety percent of the plastic items in our daily lives are used once and then chucked: grocery bags, plastic wrap, disposable cutlery, straws, coffee-cup lids. Take note of how often you rely on these products and replace them with reusable versions. It only takes a few times of bringing your own bags to the store, silverware to the office, or travel mug to Starbucks before it becomes habit.
2. Stop buying water.
Each year, close to 20 billion plastic bottles are tossed in the trash. Carry a reusable bottle in your bag, and you’ll never be caught having to resort to a Poland Spring or Evian again. If you’re nervous about the quality of your local tap water, look for a model with a built-in filter.
3. Boycott microbeads.
Those little plastic scrubbers found in so many beauty products—facial scrubs, toothpaste, body washes—might look harmless, but their tiny size allows them to slip through water-treatment plants. Unfortunately, they also look just like food to some marine animals. Opt for products with natural exfoliants, like oatmeal or salt, instead.
4. Cook more.
Not only is it healthier, but making your own meals doesn’t involve takeout containers or doggy bags. For those times when you do order in or eat out, tell the establishment you don’t need any plastic cutlery or, for some serious extra credit, bring your own food-storage containers to restaurants for leftovers.
5. Purchase items secondhand.
New toys and electronic gadgets, especially, come with all kinds of plastic packaging—from those frustrating hard-to-crack shells to twisty ties. Search the shelves of thrift stores, neighborhood garage sales, or online postings for items that are just as good when previously used. 
6. Recycle (duh).
It seems obvious, but we’re not doing a great job of it. For example, less than 14 percent of plastic packaging is recycled. Check out the number on the bottom of the container. Most beverage and liquid cleaner bottles will be #1 (PET), which is commonly accepted by most curbside recycling companies. Containers marked #2 (HDPE; typically slightly heavier-duty bottles for milk, juice, and laundry detergent) and #5 (PP; plastic cutlery, yogurt and margarine tubs, ketchup bottles) are also recyclable in some areas. 
7. Support a bag tax or ban.
Urge your elected officials to follow the lead of those in San Francisco, Chicago, and close to 150 other cities and counties by introducing or supporting legislation that would make plastic-bag use less desirable.
8. Buy in bulk.
Single-serving yogurts, travel-size toiletries, tiny packages of nuts—consider the product-to-packaging ratio of items you tend to buy often and select the bigger container instead of buying several smaller ones over time.
9. Bring your own garment bag to the dry cleaner.
Invest in a zippered fabric bag and request that your cleaned items be returned in it instead of sheathed in plastic. (And while you’re at it, make sure you’re frequenting a dry cleaner that skips the perc, a toxic chemical found in some cleaning solvents.)
10. Put pressure on manufacturers.
Though we can make a difference through our own habits, corporations obviously have a much bigger footprint. If you believe a company could be smarter about its packaging, make your voice heard.

Which one is recyclable waste?

  1. Paper

  2. Torn clothes

  3. Metallic and plastic discards

  4. All the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Recyclable wastes can be reused into new materials. For example, paper can be recycled and this will reduce deforestation because the paper is made from wood pulp. Torn clothes can be recycled to form bags and into other usable forms. Metallic and plastic discards can be melted and recycled into usable forms any number of times. Recycling reduces environmental pollution and uses less energy as compared to the production of new materials from raw materials.
Hence, all the options are correct.
So, the correct answer is 'All the above'.

Paper is waste that can be easily recycled. Used paper can be collected, out into machines and used as the paper again. This can greatly reduce the number of trees being cut for making paper. A lot of time, energy and money are also saved in this process. So, paper recycling should be carried out more often.

Thus, option B " Paper" is the correct answer.

During recycling of paper, paper is broken down into

  1. Cellulose

  2. Plastic

  3. Screens

  4. All of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The process of waste paper recycling involves mixing of used paper with water and chemicals to break it down. It is then chopped  and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called as pulp or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de-inked, bleached, and mixed with water. Then it can be made into new recycled paper or other products.

So, the correct answer is 'Cellulose'
