This year, German environmentalists collected 1.75 million signatures for a “save the bees” law requiring an immediate change toward organic farming. But to create healthy ecosystems worldwide, people in communities across the globe will need to take similar action based on sympathy for insects — and not only for bees and butterflies. The environmentalists presented immediate, science-based actions to slow down the insect decline.
“It takes specific law to preserve the amazing variety of insects in the world and we need to stop the destroying of natural habitats, limit road building in parks and reserves and produce food without the use of pesticides,” said Basset, an entomologist, “Conserving insects is not the same as conserving big animals or rare frogs. You can’t keep millions of insects in a zoo.”
A recent article in Entomology Today suggests that successful programs to save insects have a clear and simple objective and a strategically chosen audience. By focusing on bees and butterflies and other beautiful, familiar insects, it is possible to enact the law to protect the habitat of lesser known, less attractive, but equally important species.
But there are still huge gaps in information about how different species of insects are doing, especially in the tropics. “It is next to useless to weigh insects collected in an area and say that insect communities are increasing or declining.” Basset said. “We need much more specific information. That is expensive and difficult because of the effort that it takes just to identify the species, especially in the tropics. What we are doing now is to group insects by their main function, and then to determine how each group is doing in a specific area of the world.”

D.Insect Decline: Where Have All the Insects Gone?
In the summer of 2016, I gave a talk at a small conference in northern Virginia. I began by admitting that I’d never had a social-media account; I then outlined arguments for why other people should consider removing social media from their lives. The event organizers uploaded the video of my talk to YouTube. Then it was shared repeatedly on Facebook and Instagram and, eventually, viewed more than five million times. I was both pleased and annoyed by the fact that my anti-social-media talk had found such a large audience on social media.
I think of this event as typical of the conflicted relationships many of us have with Facebook, Instagram, and other social-media platforms. On the one hand, we’ve grown wary of the so-called attention economy, which, in the name of corporate profits, destroys social life gradually and offends privacy. But we also benefit from social media and hesitate to break away from it completely. Not long ago, I met a partner at a large law firm in Washington, D.C., who told me that she keeps Instagram on her phone because she misses her kids when she travels; looking through pictures of them makes her feel better.
In recent months, some of the biggest social-media companies, Facebook and Twitter, in particular, have promised various reforms. In March, Mark Zuckerberg announced a plan to move his platform toward private communication protected by end-to-end encryption (端对端加密); later that month, he put forward the establishment of a third-party group to set standards for acceptable content.
All of these approaches assume that the reformation of social media will be a complex, lengthy, and gradual process. But not everyone sees it that way. Alongside these official responses, a loose collective of developers that calls itself the IndieWeb has been creating another alternative. They are developing their own social-media platforms, which they say will preserve what’s good about social media while getting rid of what’s bad. They hope to rebuild social media according to principles that are less corporate and more humane.

Once a month, I volunteer at a meal center to help serve food to people who are in need. Despite the many other things that I need to do, I really look forward to meeting and serving these people, even if only briefly. Although my motivation begins with wanting to help others and be grateful for what I have been given, it is joy that helps bring me back when I am very busy. I first noticed this some time ago: at the end of our shift, after the kitchen and dining room have been cleaned up, I would experience a lightness of being.
A few years ago, as I was researching how kindness affected health, I came to learn that volunteerism was associated with a markedly lower risk of dying. One recent and large European study found that self-reported health scores were apparently better in volunteers than non-volunteers. Depending on the study, the decrease in death rates ranged between 20 to 60 percent or so.
How could volunteering decrease the risk of death? There are several factors at play. The first, and most primary, is decreased symptoms of stress and uplifted mood. Many studies have provided evidence that volunteering is good for depression, well-being, and social networking, among other effects. Secondly, people who volunteer regularly also make more effort to take care of themselves. They manage to pay visits to their doctor for preventive health care. Finally, people who volunteer may be more physically active. Volunteers have an obvious increase in walking each day compared to those who did not volunteer.
To try to tie this together, volunteering likely exerts its positive health effects by connecting people to others and to an activity that they find meaningful. Achieving connection, purpose, and meaning is critical to reducing stresses of life — particularly loneliness. Since stress is a major cause of disease, especially heart disease, the ability to satisfy the need for connection, purpose, and meaning can bring about beneficial changes for people. And when there is purpose and we are connected to others, we take care of ourselves.
