Garbage such as pieces of polythene bags, cloth, nails, old shoes, broken glass, broken toys and Aluminium wrappers etc. are not into compost by the red worms .
Various steps practiced in waste management are broadly divided into four steps:
Biodegradable garbage like kitchen, plant and animal wastes.
The useful garbage are ped of vegetables and fruits, egg shell, tea leaves, paper bags, pieces of paper, etc. Any garbage that can be recycled is not actually a garbage.
Redworms do not have teeth for grinding food. They have a structure called gizzards for grinding their food.
Unwanted or unusable remains or by-products of materials or food is known as waste.
We think that compost is better to use instead of chemical fertilizers. Compost fertilizers are those in which plants and animal extracts etc. are used. These fertilizers usually contain all nutrients in varying proportions. These fertilizers are not made in factories. They are prepared by the farmers themselves using indigenous methods.
They contain a large measure of organic matter. No special precautions are required while using them. In this category includes gobar khad, compost or the mixture made out of organic waste and human excreta, green manure and oil cakes etc.
Chemical fertilizers are manufactured artificially in factories with the use of chemicals. These contain large amounts of plant nutrients. These contain only one and two or three nutritional elements. For examples, Urea, Ammonium Sulphate, Super Phosphate, Potassium Sulphate, Sodium Nitrate, Calcium Sulphate etc.
a. The process of making compost with the help of redworms is called vermicomposting.
b. Vermicompost is less expensive, high yielding crops and beneficial for soil health as compared to chemical fertilizers
c. We should not use wastes that may contain salt, pickles, oil, vinegar and milk products as food for redworms because these substances attract disease-causing small organisms in pit which may harm redworms ultimately hindering the preparation of vermicompost.
a. No, it is also our responsibility. Because fresh air, water and locality helps us to make healthy. So, every citizen should care for waste disposal. We should not throw the wastes carelessly. We collect all the garbage carefully in dustbins and should save environment to pollute.
b. Yes, it is possible to reduce the problems relating to disposal of garbage by using re – cyclable materials.
We separate the garbage of our house into two groups. These are:
Group 1: Bio-Degradable
Garbage from the kitchen like fruit and vegetable peels, egg shells, waste food, tea leaves. Include newspapers, dry leaves and paper bags in this group.
Group 2: Non-Biodegradable
Piece of cloth, polythene bags, broken glass, Aluminium wrappers, nails, old shoes and broken toys.
a. We preserve properly the left-over food and reuse. We may also convert it to some other food preparation and consume.
b. In a party I and my friends choose to eat in a banana leaf platter, due to the following reasons.
We can take following steps to reduce garbage generation.
A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers only began in the 1940s.
The government provides two types of bins for collecting garbage. They are:
Blue bins: It is to collect non-biodegradable wastes like plastic, metal and glass wastes.
Green bins: It is to collect biodegradable wastes like vegetable and fruit peels, tea leaves, etc.
We should take following steps to minimize overuse of plastics:
Earthworms are called farmer’s friends because they help to increase the fertility of soil. They eat dust and make soil fertile. They are used to prepare vermicompost, which gives many nutrients to soil and ultimately to crop plants.
Plastics are not suitable for storing cooked food because they emit harmful
chemicals when they are exposed to high temperatures. Using plastics causes health problems such as heart disease, diabetes and reproductive dysfunction.
There are different methods of disposal of garbage depending on the nature of garbage. Some of the effective measures are:
All kind of plastics give out harmful gases, upon heating and burning. These gases cause many health problems, including cancer, asthma, etc.,
