2. Natural Resourcess are getting scare over time due to:
》Increase in Population.
》Increase in Statndard of living and use of energy using invention.
》Increase in transport facilities.
》Increase in industries.
The natural energy resources cannot be reused,replaced or recycled. With the increasing human activities related to energy intensive activities,Continuous supply of energy resources becomes necessary, Hence the world is facing natural energy resources scarcity.
Eg. Formation of Petroleum and natural gas takes about 70 million years. So Rapid use of such recourses will cause scarcity.
3. Deforestation is an important environmental concern. Globally, around 13 million hectares of forests disappeared.
Deforestation occurs i many ways. Most of the clearing is done for agricultural purposes grazing cattle, planting crops,commercial logging,forest fire, use of land for Insfratructure Development, Industrial Development etc.
No the optimal rate of deforestation is not zero. These days trees in Forest are being cutting daily for commercial and domestic purposes which leads to deforestation.
