Sustainability

7th September
Lo-Understand what we are learning about in this unit. Identify issues associated with the sustainability of whales.

1.he ability to be maintained at a certain rate or level.
2.

There are 86 species whales on earth!
here are 6 species of whales:

killer whale

blue whale

grey whale

humpback whale 

Beluga whale 

hector beaked whale

shepherds beaked whale

 


One reasons whales are endangered is because of whale hunting because the kill the whales. also when they build bridges over to another island they destroy fish and whales homes. fish effects the food and kills them from starvation. oil can get in they lungs in a oils spills so we should try and stop oil from going in ships.

8th September

Lo-Identify ways in which we can reduce the factors affecting whale population.

Kiera and I want to t petition for whale hunting. so that whales aren't aloud to be hunted in New Zealand. If whales go extinct then there will be over population that can course lots of disease. it will also damage the floor of the ocean. if there is over population then new disease spread ap-0

1.A species of animal or plant that is seriously at risk of extinction.

2. list 5 endangered animals 

1.The Māui dolphin
2.The Mokohinau stag beetle
3. Canterbury knobbled weevil
4. Isoetes
5.New Zealand fairy tern

3. Making safe nesting places,slowing ships down to all 12 knots so they don't hit whales and kill them, not letting dogs or humans near the animal or not over fishing.

I choose to do The Māui dolphin. the reason the Māui dolphin are endangered because of fishing nets,over fishing and ships hitting the māui dolphins. the way i would help them is having a place the only the dolphins and other fish are. where no fishing,ships or animals that kill them.
