This Catalyst article looks at OIF (Ocean Iron Fertilization) a process of pouring iron into the oceans. The theory behind it is to slow climate change by using a process that already occurs naturally. Nature has a way to draw carbon dioxide (CO2) from the air down into the ocean. If the process could be speeded up...

Many sea creatures such as crabs and shell fish are affected greatly by the levels of acid and temperatures of the ocean they live in as it prevents their outer shell development. This can lead to a depletion in numbers and a knock on effect along the food chain.

These resources include practical activities...
