Объяснение:
With the development of industrial cities that produce a huge amount of pollutants, the problem has become real.
If there was no such problem, then our planet was not in serious danger.
If not for global warming, acid rain, air and water pollution, then we did not have problems that threaten the lives of people on Earth.
If we treat our land with care, if we do not pollute it, then it can recover.
If we apply all our forces to this, there will be clean air and fertile land and there will be no environmental threat.
