Mangrove forests were traditionally viewed as A. unproductive wastelands. People therefore reasoned that their removal would improve the health of their ecosystems, leading to their degradation.
C is the proper answer. They have been reduced by using unleaded gasoline because lead can harm the air and water we breathe, so using less of it will help reduce the pollution being caused by it.
Not sure if this is multiple choice but this is what I say.
Wind, composition of the tombstone and the PH level f any moisture that may come in contact with the tombstone.
Hope this helps if I'm not too late :)
