overpopulation is very subjective so I would skip that bit.
You could do the three Rs reduce, reuse and recycle
carbon or water forest cycles
endangered animals and reasons causes, rates
food chains/webs, biomagnification (the build up of chemicals in higher trophic levels.
Rivet hypothesis, extinctions.
strange rare animals animal groups (flightless birds on islands you could use NZ as an example kiwi, moa no mammals), deep sea vents, australian ice age mega fauna.
Focus on one group species of animals whales/snakes/torpedo ray |
