3. Recycling has become easier with many public places including recycling bins right next to all garbage cans.
4. Plastic that hasn’t been recycled has extremely harmful effects to the wildlife that live in the ocean.

1. Litter is not only ugly, but also harmful to animals in national parks

Explanation:

When writing an essay in support of a point, you have to select salient points that are consistent and relatable to what you're writing about..

Younique is writing an essay in support of recycling to reduce garbage in the ocean and therefore she has to bring points that relates to side effects of throwing garbage in the ocean, how easy it is to recycle garbage and other necessary points.

The truly odd one out is option A which says "Litter is not only ugly, but also harmful to animals in national parks".

This has no direct connection to effect of garbage in the ocean or recycling so this is the piece of evidence with the least relevance to her argument.

a dictionary is the correct answer
