Marine litter is human-created waste that has been discharged into the coastal or marine environment.
Such rubbish include: plastic bottles floating in water, forgotten or abandoned fishing nets, iron cans, tires, rags. On the coast and in the reservoirs, debris can fall under the influence of physical processes occurring in the water or with the help of wind.
"Annually only 1500 tons of plastic garbage fall from the residents of St. Petersburg to the Gulf of Finland (this volume is equal to the weight of 44 subway cars)."
Plastic debris, for example a plastic bag, eventually decomposes into smaller particles - a secondary microplastic. Primary microplastic is often used in cosmetic products (body scrubs) and its content in the product is not always obvious.
At the information station on microplastics it was possible to get acquainted with information brochures about the sources of contamination of reservoirs with microplastic. and the consequences. After a brief informative lecture, the team members chose products that they would prefer in the stores, and looked for the number of components in them - microplastic elements. Such an interactive approach helped participants to think about whether they needed a product containing micro-plastic, if there are another analogues in the stores.
The information station "Sea, climate, energy" was organized by experts of the project of SPARE (school project of rational use of resources and energy). What manifestations of the changing climate do you notice in the Baltic Sea region off the coast of the Gulf of Finland? What are the consequences of climate change in the Baltic Sea? How to link human activities and the process of climate change? Is it possible to adapt to the process of climate change? And how can each of us on a personal level reduce the impact on the climate?
All these issues are proposed for discussion of the participants of the action "Clean Coast". Participants named different causes of climate change, many knew about the problem of greenhouse gases, talked about local climate changes, reasoning about how the sea and climate, climate and energy are related. After all, the heat and, to a large extent, the electrical energy that enters our homes is obtained by burning fossil fuel sources. In St. Petersburg it is basically natural gas, but also using fuel oil, and in Leningrad region somewhere - coal. The combustion is accompanied by greenhouse gas emissions. Therefore, saving energy through energy-efficient solutions - for example, windows winterization , replacing conventional incandescent light bulbs with LEDs, installing motion sensors, using light wallpaper tones in the interior of the house, installing aerators on the faucets to save water - these are just some of the solutions available to all of us to reduce the impact on the climate. An important aspect is the type of transport that is used to move around the city and travel on vacation. The passenger car and the aircraft are the leaders in terms of the number of emissions from the calculation of the amount of fuel burned per person and one kilometer. The choice is ours.
The organizers of the action "Clean Coast" made a Committee on nature management, environmental protection and ensuring environmental safety of St. Petersburg. The operator is the State Geological Unitary Enterprise "Specialized Firm Mineral". Participation in the action was taken by youth environmental organizations and movements, student groups, as well as environmentally responsible residents of the city. The competitions were held in the form of an educational quest and preparation for cleaning the garbage.
