Earth, the green planet is the only planet in our solar system known to host life. In the absence of food and water, life cannot survive. Without productive soil, the world would fail to support even half of its present organisms, or a tenth of its human population. At present, basic natural resources needed for human life are either growing scarce or are frequently polluted. In many parts of the world, soil is degraded, water is scarce, and food supplies are declining.In modern times, the waste generated by humans has become a big challenge for our environment. Several developed as well as developing countries are generating enormous amount of waste and struggling to deal with it in a sustainable way. Waste that is non-biodegradable or non-recyclable is not only filling landfills but also affecting our water bodies, grasslands, fields, climate, public health, wildlife, and so forth. Since we have limited space on earth to dispose all the waste, it is imperative to take steps to manage the waste by using the resources efficiently. Zero Waste management is a global movement designed to reduce waste in our society. The concept of 5R’s is to decrease the number of things we use and simultaneously also decrease the number of things we throw away. The intent of this article is to understand the existing global status of Municipal Solid Waste (MSW) generation as well as to explore various ways to manage ever growing volume of waste, which poses formidable challenges to both high and low-income countries of the world.
