Ocean Ecosystem Headed For Collapse within the Next 10 Years

According to a new study, worldwide global warming will lead to “disastrous” biodiversity loss. If the release of green house gases is not restricted, entire ocean ecosystems could suddenly collapse this decade.

Scientists explained that unlike anytime in human history, Earth is getting warmed so rapidly and uniformly. If these conditions persist, Earth is on course to heat up to four degrees Celsius by 2100.

Global warming is badly going to affect the Earth’s delicate ecosystem

 As temperatures are increasing beyond the tolerance of thousands of animals, the animals are getting extinct. Extinction of species is affecting food chains and food webs. With the extinction of key species, entire ecosystems like coral reefs and forests will crumble.

Research leader Alex Pigot of University College London, said, “We found that climate change risks to biodiversity don’t increase gradually. Instead, as the climate warms, within a certain area most species will be able to cope for a while, before crossing a temperature threshold, when a large proportion of the species will suddenly face conditions they’ve never experienced before.”

“It’s not a slippery slope, but a series of cliff edges, hitting different areas at different times.”

The study predicts, initially Ocean ecosystems will be hit. This is because the seas are already hit by the problems like lack of oxygen and increase in acidity and temperature. And by 2040s, a similar catastrophic collapse is likely to spread to the land.

Mark Wright, science director of the World Wildlife Fund, said, “The world is currently rightly focused on tackling the global health emergency,” “However, this new research reinforces that, after we are through this extremely difficult time, we will need renewed ambitious action to address the climate and nature crisis.”
