I recently took a trip to Kaunas, Lithuania and brought my camera to take photos. I have compiled an album of 20 photos from my visit, including pictures of the old town area, churches, and other sights around the city. The photo album provides a glimpse into some of the highlights from my travels to Kaunas.
The document summarizes the results of a survey of 50 students about their use of public transportation. Most students use cars to get to school rather than public transportation. While many students would like to get a driver's license and own a car, the document advocates using public transportation and lists its benefits. It provides statistics on how students typically commute including the time, distance, and cost of their journeys as well as the schedules of public buses. The document's goal is to promote greater use of public transportation among students.

Secondary School of Foreign Language Teaching "Vassil Levski" is a 40-year-old school located in Bourgas, Bulgaria that specializes in teaching Russian and Western languages like English, German, and French. It has over 750 students divided into 27 classes. The school has modern facilities including 15 classrooms, laboratories, and computer rooms. Teachers are well qualified and work closely with students on extracurricular activities while also participating in various local, national, and international programs.
The document discusses atmospheric pollution in Burgas, Bulgaria. It identifies the main sources of pollution as motor traffic, which accounts for 90% of atmospheric pollution by emitting nitric oxides, CO2, and particulate matter daily. Firewood and coal heating also contributes fine particles, especially in the town center. The Lukoil refinery emits a wide range of pollutants from industrial processes and leaks. Urban development and dust from construction also pollute the air. To examine pollution levels, students conducted experiments using Scotch tape in different locations, finding high amounts of particulate matter. Their conclusion is that particulate matter in combination with other emissions like NO2, SO2, CO2, NH3, and VOCs are causing a
A teacher from the Secondary School of Foreign Language Teaching ¡°Vassil Levski¡± leads students in environmental and health education projects. The teacher oversees students in grades 10 and 11 who participate in initiatives like cleaning, reforestation, and national health projects. The teacher and students work as a team to support environmental and health causes.
1) Burning fossil fuels for energy production contributes significantly to greenhouse gas emissions and climate change. Deforestation also contributes.
2) Data shows rising temperatures globally and more extreme weather events like floods and storms causing major economic losses. Projections suggest worse consequences without action.
3) The EU aims to reduce greenhouse gas emissions 20% by 2020 and increase renewable energy and energy efficiency to limit temperature rise to under 2 degrees Celsius. Individual lifestyle changes around energy and transportation habits can help prevent worst impacts of climate change.

Slovenia's energy consumption is characterized by its reliance on fossil fuels like oil and coal. Renewable energy accounts for only 10% of consumption while nuclear makes up 20%. The document outlines Slovenia's energy profile, including consumption patterns in a secondary school. It shows the school's electricity usage varies throughout the day and month, with higher consumption in winter months and evenings. Recommendations are provided to increase energy efficiency and utilize renewable energy sources like solar panels.
