To Stop an Insect Die-Out, the World Needs Pollinator-Friendly Policies, Scientist Warns
By Kerstin Palme
Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.
But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.
Insects like bees, butterflies and even certain species of beetle and ant incidentally pollinate our crops when they collect protein-rich pollen and sugary nectar, ensuring we have enough to eat.
DW spoke to Josef Settele, a professor and entomologist at the Helmholtz Centre for Environmental Research (UFZ) in the eastern German city of Halle, about whether we need to worry about our food and how politics and business could intervene to halt the insect decline.
Settele was in the global spotlight in May 2019 when the United Nations IPBES Global Assessment Report on Biodiversity and Ecosystem Services was published. In the report, the entomologist and his colleagues determined that around 1 million plant and animal species are threatened with extinction.
Insects are being hit particularly hard. The scientists estimate that around 10% of all insect species are threatened with dying out over the next few decades — and that's a conservative calculation.
Entomologist Josef Settele says we need insect-friendly agriculture to help counteract the decline in pollinators.
DW: In the report, you conclude that in some world regions 40% of wild, pollinating insects, particularly wild bee species, are already facing extinction. Why don't we just put up bee boxes and hives everywhere?
Josef Settele: That will only help so much. The wild cousins of the honeybee don't necessarily live under the guardianship of humans. And the honeybee is responsible for pollinating only a certain percentage of our crops. For instance, they pollinate just a small portion of our apples. Wild pollinators whether they be hoverflies, bumblebees or other insects like butterflies are more important in this regard.
Solitary pollinators like the leafcutter bee like to nest in tunnels, like the ones provided in this insect hotel.
So my apple harvest could be less bountiful if the honeybee is the only species available to pollinate it?
Correct but even more importantly, certain plants can't be pollinated by honeybees in the first place. Bumblebees, for instance, typically pollinate broad beans. Honeybees can't do much here really.
Broad-bean blossoms are closed and the bumblebee can easily force its way in with its wide body. Another example is alfalfa, an important forage crop that is dependent on the bumblebee. Honeybees just can't get into the blossom.
What would the global community have to fork out if all pollinating insects suddenly disappeared and our food crops had to be pollinated by hand?
Global pollination [by insects and other animals] is worth at least $235 billion a year, according to our conservative estimates. And you'd really have to expend considerable resources to imitate the animals' pollination performance. Humans just haven't mastered the technique. Look at the use of brushes. The yields are always paltry in comparison to natural pollination.
The other question is: where in the world am I doing it? If I'm in a country where the labor costs are low, then it could provide some kind of alternative. But there would be no point in trying that in Germany, for instance. Your apples would suddenly be 10 times more expensive when you take our labor costs into account.
Considering those prospects, you would think that politicians and businesses would have a big interest in stopping species loss. What courses of action are there for policy makers? What shape would pollinator-friendly politics take?
Many different factors contribute to the disappearance of insects but a lot of it is very much connected to our land use. A more sustainable use of our land needs to be encouraged. That could be achieved by, for instance, having a higher diversity of habitats and by reducing pesticides, particularly insecticides.
We really need policy that would heavily promote the production of sustainable products. So, groceries that require fewer pesticides and make more sense from an energy perspective. That means eating more plants in our diet and fewer animal-based products.
I'm not a vegetarian but the strong preference in Europe and North America for consuming meat has to change. Our high meat consumption fuels the demand for soy, which is used as a feed for cattle. By importing soy from South America, we're contributing to species extinction. That's because forests and areas that were full of species-rich ecosystems are often turned into plantations. These are grave changes that are causing habitats to disappear.
But are large, blooming monoculture plantations not good for wild pollinators?
Settele advises people to plant blooming flowers in their gardens and balconies to give bees, butterflies and other pollinators a helping hand.
Pollinators need more than just food. They need nesting habitats. Solitary wild bees lay their eggs in holes in the ground or hollow stems, the likes of which are mimicked in insect hotels. Those are basically reproductions of the shelters found in nature and where they lay their eggs.
What can I do as an individual?
Being aware of the impact of how you consume is a good start, although, that is often difficult to navigate. It's always a good idea to make sure you've got a diversity of flowering plants around your home. Even just getting in touch with nature is good.
So, just get outside into nature?
Yes! Out into nature. And bringing nature to your own front door.

The 2008 financial crisis spurred a number of youth movements including Occupy Wall Street and the Arab Spring. A decade later, this anger resurfaced in a new wave of global protests, from Hong Kong to Beirut to London, only this time driven by the children of the 2008 financial crisis.
1. Learn From the Past<p>Young people tend to be comfortable with change. Their instant adoption of technology is an example.<a target="_blank"> However, they may lack an understanding of the more permanent realities – requiring patience and </a>stoicism.</p><p>This wisdom is typically in the hands of individuals who either work within systems or who have accumulated far more tenure. This was effectively echoed by 13-year old activist, Naomi Wadler who <a href="https://www.youtube.com/watch?v=17Aa6XLZe9A" target="_blank">said</a>, "We can educate our youth a lot better. We're not delving deeper into social justice movements from the past."</p><p>Youth movements that are informed by the success and pitfalls of prior efforts offer a more promising outcome. Take for example, the Black Lives Matter (BLM) movement, co-founded by a 32-year old Alicia Garza.<span></span></p><p>Unlike the civil rights movement of the 1960's, BLM lacks central governance. This means that opponents can't attack its leadership as a means to discredit the whole movement. In the 1960's, this is exactly what happened to the civil rights movement, when critics went after Martin Luther King, stalling the collective efforts of the movement.</p><p>In fact, King spent his final year <a href="https://eu.usatoday.com/story/opinion/2018/04/04/martin-luther-king-jr-50-years-assassination-donald-trump-disapproval-column/482242002/" target="_blank">mired in public disapproval</a> with over 75% of Americans considering him "irrelevant" including 60% of African Americans.</p><p>By studying the legacy of previous efforts, BLM has managed to rally approximately <a href="https://www.washingtonpost.com/politics/big-majorities-support-protests-over-floyd-killing-and-say-police-need-to-change-poll-finds/2020/06/08/6742d52c-a9b9-11ea-9063-e69bd6520940_story.html" target="_blank">75% of the American public</a>; a feat that will undeniably ensure the longevity of its cause.</p><p>For the youth climate movement, it too must reconcile the long record of activism that predates its tenure. It ought to model itself as an intergenerational movement by giving greater credence to the activists, environmental scientists and <a href="https://www.weforum.org/agenda/2020/05/juan-manuel-santos-colombia-indigenous-peoples-coronavirus-pandemic-climate-change-environment-nature/" target="_blank">indigenous elders</a> that have fought for climate justice before its inception and ultimately signal the nuance and maturity that would activate allies within systems of power.</p>
2. Become Part of Systems Change<p>From the college campus to the coworking space, you would be hard pressed to avoid the sight of a social impact competition that invites young people to resolve some of the world's most intractable problems.<br></p><p>Unsurprisingly, this often leads to problematic and incomplete solutions. Take, for example, <a href="https://ssir.org/articles/entry/tackling_heropreneurship" target="_blank">an app for African farmers</a> developed by students who have neither farmed nor been to Africa.<br></p><p>Fortunately, there is a growing shift towards empowering young people to better diagnose the systems that uphold inequality. For example, Oxford University hosts the annual <a href="http://www.oxfordglobalchallenge.com/" target="_blank">Map the System</a> competition to celebrate some of the most promising youth-led mappings and the World Economic Forum's <a href="https://www.globalshapers.org/story" target="_blank">Global Shapers Community</a> convenes more than 7,000 young people under the age of 30 to address local, regional and global challenges.</p><p>To achieve systemic change, young changemakers must first unpack systems into <a href="https://wtf.tw/ref/meadows.pdf" target="_blank">three components</a>; elements, interconnections and functions:</p><ul><li>Elements are essentially the key stakeholders in the system. This can include individuals, land or objects.</li><li>Interconnections are the laws and social norms that bind the elements together.</li><li>Functions are the end-goals.</li></ul><p>Take for example, the persistence of sexual harassment in the workplace as a systems issue. The elements in the system would include the victim, perpetrator and other intermediary bodies including line managers and human resource teams. The interconnections could include forced arbitration laws that prohibit employees from seeking public courts and a managerial culture that protects high performing perpetrators and pressures victims into silence. In which case, the ultimate functions (or rather dysfunctions) of the system discourage victims from pursuing action and enable perpetrators and enablers to enjoy the benefits of career progression without due trial.</p><p>Systemic change is about redesigning the interconnections (the cultural norms and laws). In the example above, it involves challenging the use of private arbitrary courts and uprooting a toxic work culture. Reclaiming this intuition opens a pandora's box that ultimately allows for any given system to operate more inclusively.<br></p><p>Today, young changemakers can rely on online resources like <a href="http://systems-ledleadership.com/" target="_blank">Systems-Led-Leadership</a> to analyze any given system of inequality and then direct their unique skills and knowledge towards the most effective intervention.</p>
3. Avoid Heropreneurship<p>Daniela Papi-Thornton first coined the term <a href="http://tacklingheropreneurship.com/" target="_blank">heropreneurship</a> to describe a growing trend that credits social change to the "founder" of an organization or movement exclusively.</p><p>This culture has inspired an entire generation of young change-makers who are swayed by the allure of the "heroic" founder and whose behaviors are validated through youth awards, grants and speaking circuits that glorify a role in the limelight. This pervasive culture undercuts the entire spectrum of actors that really creates social change.</p><p>Social change does not necessarily warrant the creation of a new organization or movement. Change-makers should consider the root causes that perpetuate and uphold inequalities and then map the existing players and solutions. This process might point to scaling up the work of an existing organization or helping a local candidate run for office.<br><br>For young people who wish to create social change, their efforts – while extremely important – may go unnoticed. This is an expectation that needs to be managed.<br></p>
4. Know Your Place<p>In 2016, a political action committee entitled <a href="http://canyounot.org/" target="_blank">Can You Not</a> emerged with the aim of discouraging white men from running for office in minority districts.</p><p>Despite the comical graphics, the campaign highlights an important question for young changemakers, particularly if they advocate for issues that they have not lived: in the quest for social change, can the actions of change-makers unwittingly perpetuate injustices, even as they seek to end them?<br></p><p>In the example above, could the notion of a white man effectively assuming the role of a translator between minority communities and government only reinforce their structural underrepresentation in political decision-making? Could the desire to assume office without lived experience also signal little faith in the leadership of the very communities being served?<br></p><p>A more effective approach to social change may be to encourage such actors to take stock of the unintended consequences of misrepresentation. In doing so, they may come to appreciate the importance of "stepping back" to allow others to "step forward." More concretely, this could result in building trusted relationships with the community and eventually empowering more local voices to consider public leadership.<br></p><p>For young changemakers, it is pivotal that they assess their own standing in a given system and avoid perpetuating the very inequalities they wish to tackle.</p>

A More Targeted, Effective Kind of Activism<p>Social media has played its critical part in providing young people with a vehicle to advocate for social reform.</p><p>Whether it's <a href="https://www.theguardian.com/environment/2019/sep/23/greta-thunberg-speech-un-2019-address" target="_blank">Greta Thunberg's speech</a> during the United Nations General Assembly in 2019 or <a href="https://variety.com/2018/politics/features/emma-gonzalez-parkland-interview-1202972485/" target="_blank">Emma Gonzalez</a> rallying crowds for more stringent gun control. younger voices are swaying public opinion and pressuring political systems to operate more inclusively.<br></p><p>The impact of these extraordinary young people is inspiring, but arguably they struggle to provide a course of action for the average young person who is motivated to pursue social change. The inconvenient truth is that social reform is difficult and even more so for a young person who wrestles with challenges related to experience and credibility.<br></p><p>To be more effective, young changemakers must forge greater bonds with late-stage activists as well as potential allies within systems of power. They must also understand the systems that uphold equality and pinpoint the intervention that would most likely inspire systemic change.<br></p><p>Finally, it is pivotal that they invest in a support system and seek to dissolve <a href="https://www.weforum.org/agenda/2020/06/this-is-how-wellbeing-drives-social-change-and-why-cultural-leaders-need-to-talk-about-it" target="_blank">personal anxieties</a> that may compromise their change-making potential.</p><p>It's time for youth activism to grow up.</p>

The Supreme Court late Monday upheld a federal judge's rejection of a crucial permit for Keystone XL and blocked the Trump administration's attempt to greenlight construction of the 1,200-mile crude oil project, the third such blow to the fossil fuel industry in a day—coming just hours after the cancellation of the Atlantic Coast Pipeline and the court-ordered shutdown of the Dakota Access Pipeline.
