WWF Living Planet Report – Massive decline in the size of populations

WWF Living Planet Report – Massive decline in the size of populations

living planet reportThe World Wildlife Fund, the world’s largest conservation organization with over five million supporters, has published its 2018 Living Planet Report.

It is quite frankly very dire reading and that has resulted in the media picking up the story and highlighting it …

Let’s skip those stories and go directly to the alpha source.

Living Planet Report 2018

You can download the full 145 page report via the above link. It is very accessible and readable. It has been created by the WWF in conjunction with the Zoological Society of London (founded in 1826).

The key highlight is the rapid decline of the surveyed wildlife populations and the underlying cause is us …

Exploding human consumption is the driving force behind the unprecedented planetary change we are witnessing, through the increased demand for energy, land and water.

… 

While climate change is a growing threat, the main drivers of biodiversity decline continue to be the overexploitation of species, agriculture and land conversion.

This is Global and is impacting both Land and Sea …

Land degradation includes forest loss; while globally this loss has slowed due to reforestation and plantations it has accelerated in tropical forests that contain some of the highest levels of biodiversity on Earth. Ongoing degradation has many impacts on species, the quality of habitats and the functioning of ecosystems. Two recent studies have focused on the dramatic reductions in bee and other pollinator numbers and on the risks to soil biodiversity, critical to sustain food production and other ecosystem services.

….

Marine and freshwater ecosystems are also facing huge pressures. Almost 6 billion tonnes of fish and invertebrates have been taken from the world’s oceans since 1950. Plastic pollution has been detected in all major marine environments worldwide, from shorelines and surface waters down to the deepest parts of the ocean, including the bottom of the Mariana Trench. Freshwater habitats, such as lakes, rivers and wetlands, are the source of life for all humans yet they are also the most threatened, strongly affected by a range of factors including habitat modification, fragmentation and destruction; invasive species; overfishing; pollution; disease; and climate change.

We are faced with severe declines or changes, or to put that another way – “Business as usual” is not an option.

We need a New Global Deal

With two key global policy processes underway …

  1. The setting of new post-2020 targets for the Convention on Biological Diversity
  2. The Sustainable Development Goals

… there is currently a unique window of opportunity to reverse the trend.

Lessons can be learned from progress towards addressing other critical global issues, like climate change, and everyone – governments, business, finance, research, civil society and individuals – has a part to play.

Report Structure

The report has been sliced up into four chapters as follows …


Key Point

This is not a report that says … “It’s bad, very very bad, and we are doomed”.

Instead it is a report that lays out what is happening, and yes it is bad, very very bad (see chapter 2), but there is the potential for something different. Chapter 4 lays out a vision for that.

Between now and the end of 2020, there is a unique window of opportunity to shape a more positive future for nature and people.

One further thought – What does 60% decline mean?

Let’s be very clear about this and avoid all confusion.

They found that on average the populations of the species they studied had declined by 60%.

This is NOT the same as a 60% decline in the total number of animals, and they do make that clear.

Here are some tweets that perhaps explains this rather important distinction quite clearly …

More Tweets – the Good, The Bad, and the Ugly

In the context of the above clarification, here is how some major media outlets have been reporting this. Clearly some don’t quite grasp the distinction. This is perhaps understandable because it is a bit subtle and yet it is also a rather important distinction.

The Guardian and others really should not have dumped their science writers …

Some however did pick up on the distinction and accurately reported it …
