The document summarizes several ecological problems in Saint Petersburg, including various forms of pollution, noise from vehicles, and destruction of green spaces. Water pollution is caused by industrial waste, domestic waste, detergents, and drainage. Air pollution results from factory emissions and vehicle exhaust. Noise pollution comes primarily from cars and buses. Deforestation has reduced green spaces and increased carbon dioxide levels, contributing to global warming. Proposed solutions include moving factories out of the city, protecting green spaces, reducing waste and noise, and using alternatives to vehicles like walking or bicycling.

1. Ecological problems in Saint-
Petersburg

2. The most serious problems in Saint-
Petersburg today are:
- POLLUTION IN ITS MANY FORMS (AIR, WATER AND LAND
POLLUTION)
- NOISE FROM CARS, BUSES
- DESTRUCTION OF GREEN ZONES

3. Water pollution
THE MOST SERIOUS REASONS OF WATER POLLUTION ARE:
- INDUSTRIAL AND CHEMICAL WASTES;
- DOMESTIC WASTE;
- USE OF DETERGENTS FOR CLEANING OUR HOUSES AND CARS;
- DRAINAGE WATERS FROM IRRIGATED LANDS.

4. Air pollution
AIR POLLUTION IS THE RESULT OF OUR USE OF CHEMICALS.
FACTORIES AND PLANTS RELEASE POISONOUS CHEMICALS
INTO THE AIR. BUT THE MOST OF THE POLLUTION IN OUR
CITY COMES FROM CARS AND BUSES.

5. Noise from cars, buses
CARS NOT ONLY POLLUTE THE AIR. THEY CREATE A VERY
STRONG NOISE, WHICH IS VERY HARMFUL FOR OUR EARS. AND
IF NOTHING IS DONE, PEOPLE FROM THE CHILDHOOD CAN
HAVE PROBLEMS WITH HEARING!

6. Destruction of green zones
THE DESTRUCTION OF GREEN ZONES IS ANOTHER PROBLEM
NOWADAYS. FOR THE LAST FEW YEARS, PEOPLE HAVE CUT
DOWN AND BURNT THE BIG AREAS OF FORESTS. THIS MEANS
THERE ARE FEWER TREES AND, OF COURSE, MORE CARBON
DIOXIDE! IT CAN CAUSE THE PROCESS OF GLOBAL WARMING
OR THE GREENHOUSE EFFECT.

7. How to solve environmental problems?
- THE FACTORIES AND PLANTS MUST BE REMOVED FROM THE
CITY
- GREEN ZONES MUST BE SAVED AND CREATED. THE GREENERY
MUST BE PROTECTED AND INCREASED
- WE MUST UTILIZE THE WASTE
- WE MUST THROW AWAY LESS RUBBISH AND USE LITTER BINS
- NOISE MUST BE REDUCED
- WE MUST GO TO WORK ON FOOT (NOT BY CAR OR BUS) OR WE
CAN USE A BICYCLE FOR A LONG DISTANCE.

8. Let’s safe the place we live in
together!!!
