The correct answer to this open question is the following.
Unfortunately, there is no question here. Just a series of sentences.
What is your question? What do you want to know?
However, trying to help you we can comment on the following.
The tropical rainforest indeed is one of the oldest ecosystems. It is one of the most diverse ecosystems. Half the plant and animal species on Earth live there. This includes many that haven't been discovered yet.
If there is one place on planet Earth with such richness in diversity, is precisely in the tropical rainforest. Scientists believe that in the rainforest live 55% of animals, plants, trees, and vegetation that exist on our planet.
These scientists and researchers affirm that of the 250,000 species of plants that have been discovered on Earth, approximately 170,000 can be found in the rainforest.
So people should ask their governments to take extra care to protect the environment, especially the tropical rainforests that are avital part of the sentient beings that live on planet Earth.
Answer: Our paper's science writer, whose column I read every week, recently reported on exoplanets.
Explanation: There are three ideas here.
1. Our paper's science writer
2. They recently reported on exoplanets
3. How I read their column every week.
Two of the ideas are included in the sentence (1 and 2), and the last simply needs to be modified.
"Whose" is a determiner and associates things with other things. In the last idea, we associate their column to them: whose column... Then, we add how I read it every week and say, "...whose column I read every week."
