Write a function called remove$\_$negatives that accepts a list of numbers and returns a copy of the lists with all negative numbers removed. Use filter$()$ in your implementation, not a list comprehension!

remove$\_$negatives$([-1,3,4,-99])$ #$[3,4]$

remove$\_$negatives$([-7,0,1,2,3,4,5])$ #$[0,1,2,3,4,5]$

remove$\_$negatives$([50,60,70])$ #$[50,60,70]$

Hints:

Make sure you return a list! Remember filter does not return a list! You have to convert the result to a list yourself.

Note that $0$ is not considered negative, so it should not be filtered out!
