Explanation:

A simple sentence is constituted of a singular independent sentence. It has a subject and a predicate, and it is able to convey a full thought on its own.

On the other hand, a complex sentence is constituted of an independent sentence and a dependent one. The dependent sentence cannot stand on its own since it cannot express a full thought.

To transform the sentences in the question into simple sentences, we need to eliminate the dependent clause. One way to do that is to transform it into a phrase without a subject:

"who was dressed in black" --> dressed in black

"when she hears the news" --> to hear the news

"if you are not well" --> if unwell

i don't think it's a good idea to threaten anyone at all.

there on the beach was a struggling turtle.   around its bright green neck was a loop of soda can rings.   in order to the planet, i have made a few changes to my life.   the first change is reducing the number of straws used. the second change was to recycle.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.

you may not think straws have a large impact but they do.   imagine for every straw you sip out of a poor, , adorable turtle is being harmed.   one way i chipped in to is by using metal straws.   these straws are reusable and inexpensive.   another change is simply turning down straws.   by refusing a straw, i’m the turtles one drink at a time.  

however, the ocean just doesn't have turtles.   there are lots of creatures that live there and are harmed by all the litter.   to prevent litter from growing it’s important to recycle.   for me, i have started to buy most goods that are made out of recycled material.   pura vidas, chacos, purses, and too many other items to even count.   plus, when you buy those products they give money to charities.   not only am i the environment, but i’m also feeling better about my self.   finally, i have worked hard to clean up litter.   it is important to clean our ocean.
