We are now witnessing one of the most advanced forms of our planet. Technology has reached sky heights, and people are hungry towards having a luxurious lifestyle. But they forget that above technology there is nature, and the environment controls the nature. We always focus on our well-being and tend to forget our duty towards the environment. And to satisfy their selfish motives, some people are knowingly affecting and degrading our environment causing a serious problem for human beings as well as other species.
The environmental issues are multiplying day by day, and if these issues are not solved, then it can lead to our extinction in future. We need to be alert regarding our environment and try to contribute more and more towards its smooth functioning otherwise time will come when we might not be able to breathe properly or get adequate food for ourselves.
Due to increase in population along with rapid urbanisation, India is facing a massive challenge in waste management. More than 377 million urban people live in 7, 935 cities and towns and generate around 62 million tonnes of municipal solid wastes per year. But from them only 43 million tonnes (MT) is collected, 31 MT is dumped in landfill sites and rest 11.9 MT is sent for treatment. So, you can imagine the challenge the country is facing to maintain cleanliness in the cities.
Many municipalities deposit the wastes in dump-yards haphazardly, and this results in pollution as well as serious health issues. Landfills are the area where the wastes are buried or burnt. This is the largest, cheapest and easiest way of waste management. But landfills are the main causes of pollution because of the harmful gases like methane and carbon dioxide and also lead to groundwater as well as soil pollution. For a proper waste management, we should ensure effective segregation of waste at source and also make sure that these wastes go through various streams of recycling as well as resource recovery.
The waste should be managed in-situ for example all the parks should have decentralized units to convert the leaves and puning into compost. The residential and other entities which generate food and kitchen waste should install compact organic waste convertors. All such initiatives which recovers waste at its origin should be delployed in order to address ever increasing landfills and pollution of air, land and water.
We are moving towards creating smart cities where pollution is one of the key focus. Every smart city should have provisions to make all the waste generating units be completely off-grid, which means all type of waste shoud be recovered inside and only the waste of waste and input to re-cylcers in pre-processed state should come out.
