(CNN)Marine life in the world's oceans could recover to healthy levels in the next thirty years if decisive and urgent action is taken, an international review has found.
Marine life in the world's oceans can recover to healthy levels by 2050, researchers say
A team of scientists from around the world found marine life to be "remarkably resilient" despite damage caused by human activity and interference, they said in a review published Wednesday in science journal Nature.
Researchers said ocean populations could be restored as soon as 2050, but warned that there is limited time to achieve this change.
Rising temperatures, marine pollution and acidic water are all affecting marine life. About 70-90% of all existing coral reefs are expected to disappear in the next 20 years due to warming oceans, acidic water and pollution, scientists from the University of Hawaii Manoa said in February.
Meanwhile, other studies have shown that climate change is shrinking fish populations.
Researchers found that in spite of marine biodiversity losses during the 20th century, population losses have slowed and in some cases seen a resurgence during the 21st century.
Scientists nodded to a series of successful interventions that were shown to have an impact on ocean populations, including a resurgence in the numbers of nearly extinct humpback whales following the end of commercial hunting in the southwest Atlantic.
In the review, scientists said that the rate of recovery of marine life could be accelerated for many ocean ecosystems, and that a "substantial recovery" could be achieved within two to three decades if pressures on the world's oceans -- including climate change -- were addressed, and wide reaching interventions were put into place.
"The success of many marine conservation projects in recent years illustrates how we can make a real difference to life in our oceans if we apply the lessons learnt from them at scale and with urgency," Professor Callum Roberts from the department of environment and geography at the University of York and co-author of the study, said.
