LETTER OF THE DAY: Ocean’s long-term health threat

READER COMMENT: OUR oceans are busier every day.

Not only do marine mammals have to avoid being enmeshed in shark nets and long line fishing, but with the onset of coal ports, there is much more shipping as well as dredging taking place.

We really do need to be more cognisant that the ocean's long-term health is a web of life and humans' activities are increasingly threatening its viability.

The ocean is very forgiving, but with oil spills, plastic garbage, spoil deposits, nature's wrath from cyclonic damage to the reef, floating nets that have broken free etc, there must be a tipping point.

Many people are helping in the clean-up but we can all do our bit, whether it is depositing rubbish in beach receptacles, fishing line the same, ensuring our families understand and do the same and so on.

Are shark nets really necessary during winter with the whale migration?

Every year we see unfortunate incidents of entrapment.

It is surely time to remove them temporarily during late autumn and winter.

It is bad enough that sharks numbers are being thinned by de-finning, but to also set up traps with netting is unfair.

The ocean is their habitat - surely we can do them the courtesy of respecting that.
