We asked young scientists from a variety of fields to address this issue: The
changes required to preserve Earth’s ecosystems and biodiversity (and human
population) depend on human behavior and values, yet often conflict with current
lifestyles. Describe one way that your field can improve conservation efforts and
implementation. Several of those who responded addressed ways in which they
and their labmates could personally reduce their carbon footprints, including reducing
their use of paper, remotely attending meetings to minimize travel, ordering supplies
from vendors committed to green practices, and adhering to strict guidelines to prevent
environmental contamination from laboratory waste. Multiple respondents expressed
frustration with the limits of plastic recycling, given the necessity of plasticware in
their work, and urged more research into creative ways to break down plastics. Others
offered ways to apply the work in their fields to conservation, including some success
stories to emulate. Here, we have printed excerpts of these suggestions. Do you have

Phylogenetic systematics helped us convince fewer people to eat caviar, which has
helped to save the rarest species of sturgeons from extinction. Once the term
“caviar” was restricted to just the eggs of sturgeons (previously eggs
of many fish species could be labeled “caviar”), all of which are
endangered, people better understood that caviar are the eggs of rare animals. No
matter how appetizing the taste, few people feel good about eating the eggs of an
endangered species. Through DNA testing, we can determine whether eggs marketed as
caviar are the real thing, and if they belong to the extremely rare species from
Russia or if they are from better-managed stock.

During my fieldwork in Nepal, I came across communities that not only are sustainable
in their use of natural resources, especially forests, but also share a grounded,
ecosystem-friendly mindset. With more people belonging to “supermarket
societies,” there is decreased understanding of consumption. One way to bring
back balance in society is to put local needs first when designating power, rights,
and responsibilities regarding the use of natural resources.

A major problem in conservation is that people refuse to believe that the
disappearance of a plant or animal species is a problem. In Morelos, Mexico,
researchers addressed this by persuading local people to take ownership of their
environment. Once people felt responsible for the plants and animals around them,
they were more receptive to steps they could take to protect them.

Diversity and outreach must be built into the fabric of the scientific enterprise.
For every scientist who has risen to greatness, there are likely a thousand people
with equal potential who never had the chance to practice research due to a lack of
financial opportunity or the presence of crushing institutional and societal
discrimination. As long as that is true, solutions to the climate and biodiversity
crises will continue to elude humanity.

Conservation efforts require cross-disciplinary approaches. However, data about
Earth’s ecosystems and biodiversity are scattered among survey reports and research
literature. This information needs to be stored in a unified global biodiversity
repository that can provide global, species-wide distribution maps, allowing
biodiversity assessment across the globe in near real-time.

Myriad mechanisms exist throughout diverse plant and animal phyla that confer
resistance mechanisms to both biotic stressors (such as bacterial, fungal, and
insect pathogens) and abiotic stressors (such as drought, high salinity, and drastic
temperature shifts). These mechanisms inspire us to develop modified plants that
will be less vulnerable to accelerations of human-driven environmental

All life forms have evolved through the development of the most efficient and
effective processes, which are optimized to minimize both energy input and toxic
by-products. There are many industrial processes that can be improved by using a
biological model. Implementing such changes would reduce the impact on the ecosystem
and allow all species to flourish.

Soil transplants containing microbes favoring specific plants can restore a native
plant range quickly. Cover crops such as winter rye can prevent nutrient run-off and
retain soil. Planting nitrogen-fixing legumes can replenish a field. Soils provide
opportunities to save native plant environments and improve agriculture.

To protect our environment, we must replace fossil fuels with cleaner energy options.
One possibility, nuclear fusion, produces energy when hot hydrogen nuclei collide to
form helium. At such high temperatures, hydrogen becomes a new state of matter:
plasma. Plasma physicists and engineers around the world are working together to
learn how to control plasmas, so that the energy produced in fusion reactions can be
used to create electricity.

Metal ion pollutants in water are toxic to human health and can be devastating to an
ecosystem. Large-scale water management can also disrupt ecosystems, diverting
rivers and streams, draining lakes, and risking groundwater contamination through
the digging of boreholes. New materials offer solutions. Chemists are working toward
using high-tech materials in low-tech filters, which can be deployed as a
distributed water supply that needs no large pipelines, no dams, and no boreholes.

Norm-based persuasion messages appear to be very effective in encouraging
energy-saving and environmental protection behavior. For example, many hotel chains
have adopted conservation programs in which they post a sign asking guests to reuse
their towels during their stay. Natural field studies have revealed that norm-based
signs (such as those saying “the majority of guests join our conservation
program and reuse their towels”) are more effective than signs focused solely
on environmental protection. Others’ disapproval is also effective in decreasing
littering and electricity usage and increasing recycling. Normative appeals can
encourage conservation behavior, at no extra cost to organizations (such as

Neural engineering focuses on changing the brain to ameliorate disease. One branch of
our field, transcranial stimulation, has started to focus on brain change in healthy
individuals, helping to modulate mood or cognitive biases. A major problem in
conservation is that people want to take beneficial actions (such as recycling
walking to work, or reducing energy use) but find it hard to start the habit.
Perhaps noninvasive technologies could help them start those healthy habits by
enhancing motivation or early learning.

Preserving Earth’s ecosystems requires giving up immediate rewards (such as cheap,
unregulated fossil fuels) in favor of larger benefits that are both delayed and
intangible (such as clean air and protected biodiversity). Decision neuroscientists
have found that people who are better at visualizing their future selves are more
willing to delay gratification. In other words, we are more willing to make
sacrifices to protect our future if we can vividly imagine ourselves in that future.
Ever-improving virtual reality technology could make it possible for anyone,
regardless of imagination skills, to immerse themselves in the future dystopias that
our present actions engender, and that could prompt behavior change today that would
ensure a better tomorrow.

When people learn about what they are doing through feedback, they are aware of the
need for changes in behaviors. In the big data era, copious data about daily
behavior can be collected, integrated, and analyzed to discover behavior patterns.
Then the information can be provided in near real-time as interventions. The power
of peer effect and feedback is enormous in promoting conservation behavior.

The potential toxicity of cyanobacteria blooms can pose health risks to humans and
negatively affect ecosystem services such as drinking and recreational use of water,
fishing, and irrigation. Limiting excess nutrient concentration in water can help
control cyanobacteria blooms. To do this, scientists need the support of politicians
and decision-makers who can invest in water treatment facilities and sewage systems
and regulate the amount of fertilizers in agriculture and the types of crops planted
near water bodies. Scientists also must foster awareness in the general public about
the causes, consequences, and possible solutions for cyanobacteria blooms. Engaged
citizens can promote the changes needed through adjustments in their lifestyle and

While studying the teaching and learning of science content, science education
researchers have an opportunity to study the perceptions of, and interactions with,
science. It is these interactions that shape the future, through personal choices,
public policy, and funding for scientific research. Although content knowledge
traditionally defines learning, the future of science education may emphasize
multidisciplinary, socio-scientific concepts such as environmental protection,
conservation, climate change, and energy technologies.

Scientific data is no longer just distorted through cherry-picking and
misrepresentation. It is being dismissed entirely. To counter this, conservationists
need society to become more receptive to science. Advances in political psychology
suggest that scientific curiosity, rather than scientific literacy, makes people
more open-minded to politically sensitive topics. Therefore, conservation scientists
should not just produce more-detailed research to counter the post-truth tsunami. We
should instead appeal to the public’s curiosity by describing the way science
explores and protects the undiscovered parts of nature. In short, conservation needs
less advocacy and more Attenborough.
