Question

Which of the following are biodegradable materials?
Aluminium, wood, fruit peels, DDT, paper, glass, dung

Answer 1

Answer:

Wood, fruit peels, paper, dung

Explanation:

These all break down and can be composted.  DDT residue will eventually break down, but the damage to the surrounding environment (flora and fauna) can continue through generations.  Example: the chemicals in DDT make eggshells brittle in the area birds which reduces the population.  In the case of brown pelicans and condors, it almost led to extinction.  Glass remains forever and aluminum can be reused, but takes a very long time to break down.
