Recycle
            Recycle is the most eco-friendly method of waste disposal. In this process, the waste material is reproduced to
            create another product which can be used for some other purposes.
               • People should be encouraged to buy products that are made from recycled materials.
               • Automobiles' parts, cans, construction material, etc. are all made of metals that can be recycled.
               • Any plastic bottle or container for food storage must be recycled.


                    Factors Causing Environment Imbalance


            If organisms living in a specific environment get disturbed due to natural hazards or human intervention, then this
            causes environmental imbalance. Nowadays human intervention is more as compared to natural disasters. Human
            activity can be directly attributed to the cause of hundreds of animals and plants extinction. There is a possibility that
            if one species is lost, the entire ecosystem can stop working. We all need to be aware of these factors which are the
            reasons of our environmental imbalance, so that we can work in the direction of saving it. Some of the activities that
            are damaging our earth and environment are listed below:


            Population Explosion

            There has been a rapid rise in population all across the world in the last few decades. The rapid decline in death
            rate due to a lot of development in the medical sciences, increased birth rate due to lack of knowledge related to
            fertility and increased life expectancy are the reasons of population explosion. Population Explosion causes:


















               • More requirement of land for urbanisation and industrialisation which leads to cutting of more trees. This will
              bring land degradation and soil erosion.
               • More consumption of natural resources like food, fuel, water, coal, petrol, etc. This will bring exhaustion of
              natural resources at a much faster rate.
               • More contamination of groundwater, air and soil. All this results to drastic climatic changes and disturbs the
              ecological balance.


            Pollution

            Pollution means contamination of our surroundings that toxifies air, water, soil, etc. due to the presence of
            harmful substances that have an adverse effect on living organisms. Human activities like urbanisation,
            industrialisation, mining, and exploration are the reasons of global environmental pollution which has severe
            long term consequences.
