Many centuries ago people lived in harmony with nature because industry was not much developed. There was no ecological problem until people built lots of plants and factories. In the 21st century the ecological problems have become especially actual.

Every day  tons of harmful substances are discharged into the air, so it’s becoming harder and harder to breathe in cities. Every year rainforests are becoming smaller and smaller because people cut down  trees to sell wood. Ships and tankers constantly pollute seas and oceans with oil and other pollutants killing fish life. Moreover, many plants dump poisonous chemical wastes in rivers, lakes and seas. The Earth is our home and its protection has become one of the burning issues of the 21st century.

To improve the situation many countries have introduced modern recycling technologies. Different international organisations develop ecological programmes, for example, introducing eco-friendly transport that uses the solar energy, electricity or alternative fuel. More important is to change people’s habits and behaviour. Hiking and biking should be popularised. People should be encouraged to use public transport, plant trees and flowers, use eco-friendly packaging. All these measures will help to protect nature from destruction.
