Oceanic Ecosystems

Pros &' Cons

Positive

- Humans can help under water organisms by creating artificial reefs , bringing certain species back to that area .

- Another positive effect is when filters are made to keep major bodies of water clean.

- Preserving water can also save a lot of underwater ecosystems. By saving water, there'd be more in lakes, rivers, and oceans.

- Using less fertilizer can positively effect under water organisms , because using too much can cause chemicals to transfer into the ocean.

- Fishing less can especially help organisms under water. By fishing less, oceanic ecosystems have more time to reproduce.

Negative

- Oil spills can harm underwater ecosystems because it kills the animals and pollutes the water ways.

- littering can harm the animals especially, because they may mistake it as their prey.
