Today, coral reefs cover an area of 284,300 square kilometres. They provide more than $100 billion
worth of goods and resource services to humans each year and generate an annual net economic benefit of
about $10 billion for the global tourism industry. However, tourists always use plenty of high-powered
sunscreens to protect themselves from the intense UV rays when visiting coral reefs. Visitors may not
know that even low concentrations of chemical sunscreens - not to mention high concentrations - are
enough to cause a range of coral diseases and bleaching in the sea. In addition, most marine life cannot
survive in the tropical waters known as the blue deserts, which lack nutrients like nitrogen and
phosphorus. The coral reef is like an oasis in the desert, providing shelter for many marine organisms.
However, the coral bleaching crisis will lead to many fish and marine extinctions, further leading to the
collapse of marine ecosystems.
In Education, we made a textbook and a brochure based on different ages of audience and conducted
diversified science education activities, including lectures and experiments. In Science Communication,
we had in-depth communication with cosmetics companies and environmental NGOs, government staff,
and coral researchers based on the project's needs and participated in the synthetic biology theme meetup of COP15.
In this regard, We are committed to popularizing the relationship between coral bleaching and sunscreen use to the
public through synthetic biology, and explore a fundamental solution to the harm caused by chemical
sunscreen based on established legal procedures and market sales. We hope to make our best contribution
to the realization of cosmetics' environmental protection and environmental safety.
Coral Reef Researchers Attendees Of COP15
With the progress and development of our times, more and more people tend to go on vacation at the
seaside while also paying more attention to skincare and anti-aging. However, the public is poorly
informed about the environmental damage caused by existing sunscreens and the link between sunscreens
and coral bleaching, leading to irreversible damage to the environment while using sunscreen to protect
their skin. Therefore, it is urgent to carry out simple science popularization for the public.
As we know, WeChat and Bilibili are all popular apps in modern times. Therefore, we first set up the
official account "Jiangnan iGEM" on WeChat (Fig.1), and regularly posted introductions related to the project and
exciting articles on synthetic biology science popularization. Posting with simple words and exquisite
illustrations, we hoped to help more people understand this field.
In addition, we also created an account
"Jiangnan iGEM" on Bilibili and released a project presentation video with the theme "Save Coral Reefs
at Risks." Now the clicks are still rising, and the number of followers is considerable. We are confident
and determined to carry out the science popularization to the end.

When promoting popular science, we found that the strategy of "having a definite object in view" is
essential. Therefore, we first positioned the audience as primary and middle school students.
On May 15, 2021, the school of Biological Engineering of Jiangnan University held a public Science Day
activity themed "From Life Science to Biological Manufacturing," which involved more than 100
students and parents from primary and secondary schools in Wuxi who signed up through open channels.
The content of this activity included popular science lectures (Fig.2), model building, exciting experiments (Fig.3), etc.
Our iGEM team also participated in the activity. Considering that the student participants are young, we
chose to hold a science lecture titled "DNA, the magic code in our body" and explained the role of DNA
in our body simply and understandably. In the course of the lecture, we asked the children to build their
own DNA models to help them better understand the structure of DNA. After the lecture, we
accompanied the visiting children and their parents into the laboratory. We also jointly completed some
interesting experimental projects, such as micro drawing plate bacteria, microscope observation, and
bottle blowing balloons, enabling the children to observe the morphology of microorganisms and
understand the use of the optical microscope.
After this activity, we found that primary and secondary school students know little about biological
science knowledge, but they have a strong awareness of environmental protection anyway. Primary and
middle school students are at their best age to develop an interest in science. We believe that educating
them about synthetic biology will improve their environmental awareness and thinking skills to a great
extent. We also believe that many of them may gain inspiration from this experience and use their
wisdom to solve and manage environmental problems in the future.

In China's education system, most students begin to receive systematic biology curriculum education at
the middle school stage, further divided into two parts: junior middle school stage and senior high school
stage.
Biology is a compulsory course in junior middle school as part of mandatory nine-year education, which
covers the basic knowledge of cells, animals, plants, and ecosystems, enabling junior middle school
students to understand fundamental biology. Then in high school, biology is an elective course, which
introduces some in-depth knowledge of bio macromolecule, genetics, genetic engineering, and so on
based on what the students have learned in middle school. High school students will choose whether to
learn biology based on their future career planning. Since synthetic biology course is only offered at the
university level, knowledge related to ocean and coral reefs is rarely mentioned in middle school or high
school. We believe that middle and high school students are the main force to promote the popularization
of science and make more people understand and engage in synthetic biology research. Therefore, we
then targeted our audience at middle and high school students.
Since this group has relatively completed cognitive reading and thinking discrimination and has a specific
basis for learning biology, we made a simple popular science textbook. This brochure mainly introduces
coral reefs and the bleaching phenomenon, providing some treatment methods to solve coral reef
bleaching, and finally extending to synthetic biology. We hope that students can have a preliminary
understanding of this field and appreciate its importance from the application and prospect of synthetic
biology.
