In the future the place where we will live is in great danger. There will be many things that negatively affect the Earth. Emissions from factories and exhaust fumes, deforestation, air poisoning and water pollution, ozone depletion and global warming are the challenges that modern man must face. As you can imagine, there will be many serious problems and these solutions may not be effective. The main task is to save the planet, which is on the brink of destruction. I think we should also look for alternative energy sources. It can be wind, water and solar energy. All over the world, scientists are trying, looking for ways to rationally use resources, therefore, I hope that in the future there will be a chance for success. We should also remember about the air. The easiest way to deal with air pollution is to plant trees and eliminate the source of the pollution. Planting a tree is very simple and requires little effort. All it takes is a desire to improve the situation and stop being lazy. The earth is the place where we live, it is our home and our task is to protect it and appreciate what it gives us.
