A material or substance is considered to be a waste if when they are no longer useful or purposeful; and are thus discarded.
In some societies, we see waste materials all around. Apart from the fact that these waste are unpleasant to the eyes, they will also negatively affect national growth and development. In addition, inappropriately disposed wastes will promote the spread of diseases and (deaths) in areas where they are present.
Below are some of the causes of increasing wastes in various societies:
The larger the number of people in a society, the increase in the amount of waste produced.
Overpopulation will directly affect the increased turnout of waste materials from homes, market places and industries.
Note: Waste generated by the populace can be put into various types.
When funds allocated to waste management are siphoned, the society and its inhabitants will suffer. This is one of the many reasons for the presence of landfill waste in a society.
Corruption is a disease that eats up the society, either directly or indirectly.
In some cases, trucks meant to evacuate wastes from residential areas fail to show up because they are yet to be paid by the government for a previously done job.
The above instance results in the accumulation of wastes within these environments.
Education is always considered as the key to every successful society.
Oftentimes, market places and even residential environments are seen to be littered with various waste materials. If the residents were properly educated on the inappropriateness and dangers of their actions, the dumping of waste in these streets (and market places) will be reduced.
Note: The power of education should never be underestimated in all facets of life.
Educating and creating awareness to the citizens of a country will go a long way in reducing waste in the affected neighborhoods.
When a nation advances in technology, there will be a corresponding increase in the production of non-biodegradable waste like metal chips, rubbers and plastics.
Non-biodegradable wastes cannot be broken down and hence will always persist in landfills as solid waste.
Some people would rather discard their household waste just anywhere because they are too lazy to go to an appropriate waste dump site, perhaps because of distance.
Certain residents would rather litter the environment with various kinds of waste because they intend to avoid the payment of waste disposal fee (at waste disposal and management sites).
The presence of a few recycling industries in a society will result in the accumulation of excess waste.
When waste materials are properly recycled, new products will become cheaper since the cost of production becomes reduced from these recycled wastes. (That is, waste materials becomes raw materials for various production industries).
It is the function of production industries to pick up necessary waste materials and recycle them into new products through production.
When the people living in a society constantly dump waste materials anywhere; and without any form of fine or punishment; the act of improper waste disposal will be encouraged.
Personally, I feel bad each time I see people dump waste materials like the sachet, plastics, seeds and back of fruits (before or after they are consumed).
They consciously (or unconsciously) dump these wastes on the streets and major roads without any thought on the impending harmful effect of such waste.
Using the city of Lagos as an instance, a government agency named KAI (Kick Against Indiscipline) was previously establish to penalize and arrest offenders (that dispose waste inappropriately alongside other crimes) within the Lagos Metropolis. During this period, I discovered that city of Lagos became cleaner because most people adhered to the agency's rule while the culprits were indeed penalized.
Presently, it appears that KAI functions no longer in Lagos State. The has made some people go back to this unhealthy act.

Weight can be defined as the force of gravity acting on an object. If you traveled to space, you would be weightless because there isn't any force of gravity acting there. We all have weight on earth becasue the force of gravity acts here. Weight is measured in Newton
Massis the amount or quantity of matter/material contained in a body, For instance, everything you are composed of, both from within and outside will make up your mass. Mass is constant throughout the universe. You will have the same mass on earth and moon. Mass is measured in gram or kilogram. Mass is quite different from weight.
Matter is anything that has mass and occupy space. Matter can exist in four states namely:
