Other 3 impacts to improve ecology in our hometown Weather change is a threatening measure in our contemporary world. Enormous quantity of factory and plants actively participate in polution of the Earth's atmosphere. Enterprises of my hometown are part of the global pollution and climate changing system. Since the second half of 1990s coal mines, machine building plants has fought againts side-effects of their work. Great result has been achieved by the current moment but there are some recommendations they should do to increase both local and global ecological situation. The first recommendation is our enterprises should set up new cleaning filters. The filters detain more dangerous micro particles and period of service is more in comparance with filters which are working now. The next point is to consider current situation around so called light and noise pollution. Light is important in night time, but to illuminate every square meter is redundant. The global market offers to acquire special noise filters. Feedbacks about their leverage are very positive. The industrial sector of our region should order for testing purposes a few filters and in case of sucessful tests the sector representatives set up everywhere where it is possible. The last trait to reduce negative climate changing is trees planting and grass sowing. The decoration of our hometown landscape is a big donation into recovery the atmosphere of our region and the Globe too. Everyone wants to live the whole life in a beautiful city. Generalizing the written above, three recommendation should be executed to get rid of ecological negative traits. They are exploiting of new cleaning filters, diminishing noize and light pollusion and planting of new trees and grass sowing.
