The patch area in square kilometers is 1.59*10⁻⁹ km₂
Why?
This is an unit conversion problem. We have to convert from cm² to km². We can do that by knowing that there are 100 cm in 1 m, and 1000 m in 1 km, so 100000 cm=1km. Knowing that we can apply the following conversion factor:
Now to convert this value to scientific notation, we have to move the decimal point to the right until we get a whole number, and the exponent of the number 10 is going to be the number of spaces we moved to the right (negative), so the final answer is:
Have a nice day!

Explanation:
When I was growing up, one of the most popular cartoons was a little possum whose name was Pogo. He often said
“We have met the enemy and he is us.”
It is something Pogo said more than once. We are the problem with biodiversity being threatened.
We clear land for agriculture, not only in Canada and the United States, but in places like Brazil where it matters what is done to the environment. Those trees are the planet's lungs. Whole environmental groups are devoted to stopping the harvesting of trees that are hundreds of years old.
Our oceans have become cesspools of plastic.
Our rivers have become dumping grounds for all kinds of pollutants like paint and car tires to name just a couple.
Our landscape has been cluttered by billboards advertising things that are hundreds of miles away.
There's mining, oil, and other industries that make Mother Nature shudder every time they come near her.
