The Biggest Threats to Earth’s Biodiversity

Biodiversity benefits humanity in many ways.

It helps make the global economy more resilient, it functions as an integral part of our culture and identity, and research has shown it’s even linked to our physical health.

However, despite its importance, Earth’s biodiversity has decreased significantly over the last few decades. In fact, between 1970 and 2016, the population of vertebrate species fell by 68% on average worldwide. What’s causing this global decline?

Today’s graphic uses data from WWF’s Living Planet Report 2020 to illustrate the biggest threats to Earth’s biodiversity, and the impact each threat has had globally.

Measuring the Loss of Biodiversity

Before looking at biodiversity’s biggest threats, first thing’s first—how exactly has biodiversity changed over the years?

WWF uses the Living Planet Index (LPI) to measure biodiversity worldwide. Using data from over 4,000 different species, LPI tracks the abundance of mammals, birds, fish, reptiles, and amphibians across the globe.

Here’s a look at each region’s average decline between 1970 and 2016:

RankRegionAverage decline (between 1970 and 2016)
1Latin America & Caribbean94%
2Africa65%
3Asia Pacific45%
4North America33%
5Europe and Central Asia24%

Latin America & Caribbean has seen the biggest drop in biodiversity at 94%. This region’s drastic decline has been mainly driven by declining reptile, amphibian, and fish populations.

Despite varying rates of loss between regions, it’s clear that overall, biodiversity is on the decline. What main factors are driving this loss, and how do these threats differ from region to region?

Biggest Threats to Biodiversity, Overall

While it’s challenging to create an exhaustive list, WWF has identified five major threats and shown each threats proportional impact, averaged across all regions:

ThreatProportion of threat (average across all regions)
Changes in land and sea use50%
Species overexploitation24%
Invasive species and disease13%
Pollution7%
Climate Change6%

Across the board, changes in land and sea use account for the largest portion of loss, making up 50% of recorded threats to biodiversity on average. This makes sense, considering that approximately one acre of the Earth’s rainforests is disappearing every two seconds.

Species overexploitation is the second biggest threat at 24% on average, while invasive species takes the third spot at 13%.

Biggest Threats to Biodiversity, By Region

When looking at the regional breakdown, the order of threats in terms of biodiversity impact is relatively consistent across all regions—however, there are a few discrepancies:

In Latin America and Caribbean, climate change has been a bigger biodiversity threat than in other regions, and this is possibly linked to an increase in natural disasters. Between 2000 and 2013, the region experienced 613 extreme climate and hydro-meteorological events, from typhoons and hurricanes to flash floods and droughts.

Another notable variation from the mean is species over-exploitation in Africa, which makes up 35% of the region’s threats. This is higher than in other regions, which sit around 18-27%.

While the regional breakdowns differ slightly from place to place, one thing remains constant across the board—all species, no matter how small, play an important role in the maintenance of Earth’s ecosystems.

Will we continue to see a steady decline in Earth’s biodiversity, or will things level out in the near future?

Fact Check: The Truth Behind Five ESG Myths

ESG investing continues to break fund inflow records. In this infographic, we unpack five common ESG myths.

ESG Myths

Fact Check: The Truth Behind 5 ESG Myths

In 2021, investors continue to embrace environmental, social, and governance (ESG) investments at record levels.

In the first quarter of 2021, global ESG fund inflows outpaced the last four consecutive quarters, reaching $2 trillion. But while ESG gains rapid momentum, the CFA Institute shows that 33% of professional investors surveyed feel they have insufficient knowledge for considering ESG issues.

To help investors understand this growing trend, this infographic from MSCI helps provide a fact check on five common ESG myths.

1. “ESG Comes at the Expense of Investment Performance”

Fact Check: Not necessarily

Worldwide, ESG-focused companies have not only seen higher returns, but stronger earnings growth and dividends.

Returns by ESG RatingsEarnings Growth*Active Return**Dividends and Buybacks
Top tier2.89%1.31%0.28%
Middle tier1.35%0.12%-0.02%
Bottom tier-9.22%-1.25%-0.05%

Source: MSCI ESG Research LLC (Dec, 2020)
*Contribution of earnings growth and dividends/buybacks to active return
**Active return is the additional gain or loss compared to it respective benchmark

In fact, a separate study from the CFA Institute shows that 35% of investment professionals invest in ESG to improve their financial returns.

2. “Investors Talk About ESG But Don’t Invest In It”

Fact Check: False

Global ESG assets under management (AUM) in ETFs have grown from $6 billion in 2015 to $150 billion in 2020. In just five years, ESG AUM have accelerated 25 times.

Today, money managers are focusing on the following top five issues:

Top ESG IssuesAssets AffectedGrowth in Assets Affected (2018-2020)
Climate change / carbon emissions $4.18T39%
Anti-corruption$2.44T10%
Board issues$2.39T66%
Sustainable natural resources / agriculture$2.38T81%
Executive pay$2.22T122%

Source: US SIF Foundation (Nov, 2020)

Meanwhile, over 1,500 shareholder resolutions focused on ESG-related matters were filed between 2018-2020. Not only are investors turning to ESG assets, but they are placing higher demands on corporate responsibility.

3. “ESG Investment Strategies Eliminate Entire Sectors”

Fact Check: Not necessarily

First, not all ESG investment approaches are exclusionary.

For instance, in North America roughly 51% of ESG ETFs used an ESG integration approach as of Dec. 31, 2020. In an ESG integration approach, ESG risks and opportunities are analyzed with the goal to support long-term returns.

By comparison, values and screens approaches, which accounted for over 22% of ESG ETFs in North America may screen out specific business activities, such as alcohol or tobacco, or sectors such as oil & gas.

Percentage of ESG TypeIntegrationValues & ScreensThematicImpact
North America50.9%22.5%20.7%5.9%
Asia57.8%34.6%3.8%3.8%
Europe30.8%60.6%8.6%0.0%
Australia28.6%71.4%0.0%0.0%

Source: Refinitiv/Lipper and MSCI ESG Research LLC as of Dec 31, 2020 (MSCI Feb, 2021)

Second, companies are assessed on a sector-specific basis where ESG leaders and laggards are identified within each sector in comparison to peers. In other words, ESG doesn’t mean eliminating exposure to entire sectors. Instead, investors can choose from a range of companies based on their ESG ratings quality.

4. “ESG Investing Is Only For Millennials”

Fact Check: False

Although ESG is popular among millennials, ESG investing is being driven by the entire investor population. In 2019, one study finds that 85% of the general population expressed interest in ESG investing.

Interest in Sustainable InvestingGeneral PopulationMillennials
201985%95%
201571%84%

Source: US SIF Foundation (Nov, 2020)

Sustainable investing goes far beyond millennials—ESG disclosures are quickly becoming requirements for key industry participants, such as institutional investors and listed companies.

5. “ESG Investing is Here to Stay”

Fact Check: True

Climbing 28% in 2020 alone, over 3,000 signatories have committed to the UN Principles of Responsible Investment. As of the first quarter of 2021, 313 global organizations and 33 asset owners have been newly added.

20192,370$86.3T

*As of Mar, 2020

Central to ESG’s growth is the availability of ESG investments. ESG investing has become more widely accessible—which wasn’t always the case. Over the last decade, the global number of ESG ETFs has grown from 46 to 497.

Why the Facts Matter

As ESG investments continue to play an even greater role in investor portfolios, it’s important to focus on data rather than prevailing ESG myths that are not backed by fact.

Given the recent momentum in investment returns and ESG adoption, data-driven evidence empowers investors to build more sustainable portfolios that better align with their investment objectives.

Visualizing the Depth of the Great Lakes

The five Great Lakes account for 21% of the world’s total freshwater. This bathymetric visualization dives into just how deep they are.

Visualized: The Depth of The Great Lakes

Click here to view the interactive version of the visualization on Tableau.

As the seasons change, it’s natural to want to enjoy the outdoors to the fullest. The Great Lakes, a distinct geographical region sandwiched between the U.S. and Canada, provides immense opportunity for millions of tourists to do just that every year.

But did you know that altogether the Great Lakes contain 21% of the world’s surface freshwater by volume—or 84% of the surface freshwater in North America?

This bathymetric visualization, created by Alex Varlamov, helps put the sheer size and depth of all five of the Great Lakes into perspective.

What is Bathymetry?

Bathymetry is the study of the underwater depth of ocean or lake floors, a geographical science that falls under the wider umbrella of hydrography.

In essence, it is the underwater equivalent of topography. Contour lines help to represent and study the physical features of bodies of water, from oceans to lakes.

Most bathymetric studies are conducted via sonar systems, transmitting pulses that ‘ping’ off the ocean and lake floor, uncovering what lies below.

The Depth of the Great Lakes, Compared

High on the list of the world’s largest lakes, the five Great Lakes altogether account for over 244,700 km² (94,250 mi²) in total surface area. That’s bigger than the entire United Kingdom.

Lake Superior emerges, well, superior in terms of total surface area, water volume, and both average and maximum depth.

406 m
(1,333 ft)

Lake Erie is by far the shallowest of the lakes, with an average depth of just 19 meters (62 ft). That means on average, Lake Superior is about eight times deeper.

With that in mind, one drawback of the visualization is that it doesn’t provide an accurate view of how deep these lakes are in relation to one another.

For that, check out this additional visualization also created by Alex Varlamov, which is scaled to the same 20 meter step—in this view, Lake Erie practically disappears.

More than Meets the Eye

The Great Lakes are not only notable for their form, but also their function—they’re a crucial waterway contributing to the economy of the area, supporting over 50 million jobs and contributing $6 trillion to gross domestic product (GDP).

Together, the five Great Lakes feed into the Atlantic Ocean—and when we expand the scope to compare these lakes to vast oceans, trenches, and drill holes, the depth of the Great Lakes barely scratches the surface.
