We can see that in these days, environment is being harsh day by day. The quality of air is also worse. People are facing various environmental problems all over the world. The are several reasons behind it.
Different people have different opinions related with the environmental concerns. Some people believe that environment is degrading due to the loss of particular species of plants and animals, while other say that there are other factors as well for causing these problems. In my opinion, both the views are equally correct.
In ancient times, there used to be dense forest everywhere. In that time, environment was so good. People could get fresh air. There were many endangered species of plants and animals, which protected the environment in proper way by balancing ecosystem. Many plants absorbed harmful gases and poisons to protect humans and surroundings. In the same way, some reptile animals like snakes, lizards, etc. also used to do the same. Due to the vast growth of industries and population of human beings, these endangered species were slowly reduced. Forests were destroyed,thousands of animals became homeless and various herbal plants were damaged.
Some times, this problem can caused naturally. Various natural things like landslides, soil erosion, volcanic eruption, and earthquake can be the reasons for the degradation of the environment. Additionally, artificial things like world war, explosion of bombs, and others also make environment polluted. Humans, themselves, are the main responsible for these problems. Their unusual activities like throwing garbage everywhere, not being serious about the beauty of surrounding, opening more and more factories, and many others are causing various environmental problems.
In conclusion, from both views, the environmental concerns are due to the loss of plants and animals as well as the behaviour of humans.
