here is truth why i chosse c instead because we need to regulated and scheduled our tree cutting i prefer because. So that we can save our own trees and what about the animals so that is why i chosse c so that we can save the enviroment

i chosse d instead of c in this number because what if the coral reefs are now dead and so that is why we need to check its active ingredients in the sunscreen if its alive so that is fine for the habitats of the water

I chosse c again because panda is an endangered species.

i chosse a this time if we keep on planting trees for our survival we might get food from trees and you can build a house so that is why trees are important to our world
