Biodiversity decline (insects), Nitrogen problem (het stikstofprobleem), climate change and pollution (plastics)

Biodiversity decline (insects)

Watch this video and: 

--> note down as many causes for the decline of insects as you can. (You have to be able to describe each cause in your test)

--> note down as many solutions as possible, you can do yourself to stop the decline of insects in your own neighbourhood/garden/balcony.

Biodiversity decline (insects)

In class you have made notes during watching this video. Now you can:

--> describe at least 3 causes of insect decline

--> describe at least 2 solutions to improve the biodiversity of insects in your own neighbourhood, garden or balcony.

The nitrogen problem

--> What is the relation between nitrogen and the decline of biodiversity (the amount of species of plants and animals)?

--> Write down several examples of solutions (you can use) to reduce the amount of nitrogen. (Interesting fact: several of these solutions also help to reduce the next prolbem: climate change)

the nitrogen problem

In class you have made notes during watching this video. Now you can:

--> Explain why an increase of nitrogen causes biodiversity decline.

--> describe several things you can do to reduce the amount of nitrogen (which in many cases also helps to reduce your inpact on climate change).

Climate change

--> Why is (the) climate changing? (This is different from "what is causing climate change; now you have to explain it).

--> What is ocean acidification and what are causes and effect?

--> Come up with at least 4 real examples of things you can do to stop climate change (which examples are related to the nitrogen problem as well?)

Climate change

In class you have made notes during watching this video. Now you can answer the following questions:

--> Why is (the) climate changing?

--> What is ocean acidification and what are causes and effect?

--> Which 4 real examples of things can you do to stop climate change? (which examples are related to the nitrogen problem as well?)

Pollution: plastics

How do plastics become part of our food chain? (Yes, also in your body it is possible to find plastics)

--> Describe your answer as best as you can, inspired by this video.

How can plastics become part of our food chain?

Discussion in class.
