<human>:  A paper company decides to operate their business more sustainably. They decide that for every tree they chop down, they want to plant three more. If the company chops down 200 trees in the first half of the year and 300 more trees in the second half of the year, how many more trees does the company need to plant?
<bot>: How many trees has the company chopped down? ** The company has chopped down a total of 200 + 300 = <<200+300=500>>500 trees throughout the year.
How many trees does the company need to plant? ** They plant 3 trees for every tree they chop so they need to plant 500 trees * 3 = <<500*3=1500>>1500 trees.
