On the topic Eco-problems in my hometown Rostov-on-Don

Think the main problem is air pollution. When air is

polluted it changes the and damages animals' and our health.
Factories and plants pollute the environment
When people throw litter in the river they cause the second problem - water pollution.

we leave litter in the forests, nature is damaged.
People

from litter damaged not only the nature of the forest, but also birds and forest animals.
A lot of people don't recycle paper, they cut down trees to make new paper.
Every day is cut down more than 100 trees

pollute our planet and harm to health.
I think that everyone

should take care of the nature of their city because every day it less and less
Plant new trees that would improve the air in your city and be healthier. Do not litter the river of lakes glass and plastic. It will not take you much time but the city will be cleaner One person can do a lot for your city. We all live on one planet so it is important to protect and look after for nature.
Earth, air and water are important for flowers, trees, animals and people. We must protect our planet and try to save it!
