Of course, there are all different kinds of environmental problems and I do not know which problem you want discussed. I will write about global warming.
One of the major environmental problems today is global warming. It is caused by an excess of carbon dioxide in the atmosphere. This causes what is known as a "greenhouse effect."
The major effect of this greenhouse effect is to raise the temperature of the world as a whole. If this continues, climate patterns around the world will change. In addition, sea levels will probably rise, which will be bad for low-lying areas.
There are many possible solutions, all of them have to do with emitting less carbon dioxide -- either by using less energy or by finding energy sources that do not emit carbon dioxide.
Currently most of the people prefer fast foods and foods cooked in microwave oven instead of preparing and cooking homemade foods that takes longer. The trend of having food quickly has advantages and disadvantages either.
In my opinion, the only benefit of eating fast foods and foods cooked in microwave oven is to provide to save time. There are many people who live in rush and have loads to do. In this case, it’s hard to find time to cook a meal. Therefore fast foods and foods cooked in microwave oven emerge as a solution for those people. But there are many drawbacks of fast foods that outweigh this advantage. Since fast food restaruants became widespread, people do not eat balanced and nutrious. That causes serious health problems later.Especially for children, to eat balanced, healthy and nutrious is essential for proper growth. To eat so much fast foods in childhood might cause perminent growth disorders that might affect on children’s psychology as well. Rates of obesity increases inevitably just as proliferation of eating fast foods. Obesity is not just to be overweight. It results significant health problems. In some countries, obesity rates are so high that the governments of that countries must take measures instantly to prevent this increase. Also the belief that microwave ovens trigger cancer is an noteworthy one, and one that i believe in. There is the same thought about fast foods too.
All things considered, we can conclude that to eat fast foods and foods cooked microwave ovens is to play with our healths for the sake of saving a little time. When we lose our health, neither money, nor time can get it back.
