Scientists at WWF and the Zoological Society of London claim that creatures across land, river and sea are being decimated as humans kill them for food in "unsustainable" numbers.
Responding to the report's findings, executive director at A Rocha, Chris Naylor, believes it is time Christians moved to the 'forefront' of campaigns to reverse the decline in wild animals across the planet.
Speaking on Premier's News Hour, he said: "We're shamed to a certain extent by our secular peers, who often get this more than we do.
"As a global Church we are not at the forefront of looking after God's extraordinarily beautiful and amazing world as we should be."
The report shows that the biggest recorded threat to biodiversity comes from the combined impacts of habitat loss and degradation, driven by unsustainable human consumption.
It also notes that the impact of climate change is becoming an increasing concern.
David Nussbaum, chief executive of WWF UK, said: "The scale of the destruction highlighted in this report should be a wake-up call for us all.
"But next year - when countries of the world are due to come together to agree on a new global climate agreement, as well as a set of sustainable development goals - presents us with a unique opportunity to reverse the trends we see in the Living Planet Report.
"We all - politicians, businesses and people - have an interest, and a responsibility, to act to ensure we protect what we all value: a healthy future for both people and nature."
The Living Planet Report 2014 is the 10th edition of WWF's biennial flagship publication.
It uses the Living Planet Index, a database maintained by the Zoological Society of London, which tracks more than 10,000 vertebrate species populations from around the world.
The index reveals a continued decline in these populations and that this global trend is not slowing down.
The report also highlights that we are using more resources than our planet can continue to provide and that, if this continues, we will create even greater ecological problems in the years to come.
In 2015, world leaders will put together two potentially critical global agreements: the Post-2015 Development Framework, which will include sustainable development goals to be achieved by all countries by 2030; and the UN Framework Convention on Climate Change.
