There are various reasons for which we should be vigilant about matters related to forests.
1. A decrease in forest area would lead to an increase in carbondioxide in air. This will increase the temperature of earth’s atmosphere.
2. Soil erosion would occur if there are no forests.
3. Floods would be more frequent in absence of forests.
4. Due to deforestation many areas will slowly get converted into deserts. Therefore, we need to conserve our forest.
