Transport belongs to the main pollutants of atmospheric air, reservoirs and soils. Industrial waste is not less dangerous pollutant of environment.

In Ukraine, the main source of waste generation are enterprises of machine-building, fuel and energy, construction, agro-industrial complexes, utilities and others.

All the above factors have a detrimental effect on the environmental situation in Ukraine and cause such negative consequences as the greenhouse effect, acid rain, ozone depletion. In the case of further preservation of this state of affairs, our state risks slipping in terms of environmental danger to human life to the level of African countries.

To prevent this from happening, you need to follow seven rules:

Be energy efficient in everyday life

Choose the most environmentally friendly transport

Refuse disposable bottles and utensils

Economize water

Buy less and don't throw away

Sort garbage and give it for recycling

Abandon plastic bags
