Why should we worry about the conditions and issues related to forest far from us

Smoke from The Conversation asked What’s in wildfire smoke that’s a problem? When we talk about air quality, we often talk about PM2.5.

Partners After so many smoke-filled summers and record-setting burns, residents of Western North America are no strangers to wildfires. Still, many questions are circulating about Is climate change fueling these fires? Does the long history of fighting every fire play a role? Should we leave more fires to burn? What can be done about Western forests’ vulnerability to wildfires and climate change? We invited 40 fire and forest ecologists living across the Western U.S. and Canada to examine the latest research and answer these questions in a So, why are wildfires getting worse? Climate change is a big part of it. Summer wildfire seasons are Ironically, a chron...

There are various reasons for which we should be vigilant about matters related to forests. • A decrease in forest area would lead to an increase in carbon dioxide in air. This will lead to an increase of earth’s temperature. • Soil erosion would occur if there are no forests. • Floods would be more frequent in absence of forests. • Forests provide shelter and food to animals. When forests are adversely affected, the habitats of wild animals are also adversely affected. • Therefore, we need to conserve our forests.

Forests are very important resources. We should be careful and concerned about the issues related to forest due to following reasons: 1. If there are no forests, there would be more floods and more soil erosion. 2. Forests affect the global environment in a great way. For example; reduced forest cover in a particular area leads to global warming which affects the whole earth. 3. Forests are the dwelling of many animals. Deforestation will endanger our life and environment. 4. In the absence of trees and plants, the animals will not get food and shelter. 5. Forests provide us large number of useful products including wood, fruits and medicines. These products would not be available in the absence of trees and plants.

Answer: There are various reasons for which we should be vigilant about matters related to forests. (i) A decrease in forest area would lead to an increase in carbon dioxide in air. This will lead to an increase of earth’s temperature. (ii) Soil erosion would occur if there are no forests. (iii) Floods would be more frequent in absence of forests. (iv) Forests provide shelter and food to animals. When forests are adversely affected, the habitats of wild animals are also adversely affected. Therefore, we need to conserve our forests.

Forests indirectly or directly influence human life. They control floods and rainfall. They maintain balance of oxygen and carbon dioxide in the atmosphere. They are also provider of many useful items needed by us in our daily life. They provide food, shelter and habitat to many animals also. They form a part of food web. So, we should worry about the conditions and issues related to forests far from us.
