Fossil fuels which are traditionally used by human beings everywhere as an energy sources are non-renewable sources of energy. These sources of energy are limited and will disappear after some time. They are being consumed at a large rate. Therefore, we should conserve the energy sources. Hence, we should look for alternate sources of energy.
The disadvantages of fossil fuels are: 1. Burning of coal and petroleum produces a lot of pollutants causing air pollution. 2. Fossil fuels release oxides of carbon, nitrogen, sulphur, etc. that cause acid rain, which affects the soil fertility and potable water. 3. Burning of fossil fuels produce gRead more

1. Burning of coal and petroleum produces a lot of pollutants causing air pollution.
2. Fossil fuels release oxides of carbon, nitrogen, sulphur, etc. that cause acid rain, which affects the soil fertility and potable water.
3. Burning of fossil fuels produce gases such as carbon dioxide that causes global warming.
Non-biodegradable substances affect the environment by: 1. They contaminate soil and water resources as they cannot be decomposed by micro-organisms. 2. These substances, when accidentally eaten by stray animals, can harm them and can even cause their death.
Non-biodegradable substances affect the environment by:
1. They contaminate soil and water resources as they cannot be decomposed by micro-organisms.
2. These substances, when accidentally eaten by stray animals, can harm them and can even cause their death.
Biodegradable substances affect the environment by: 1. The biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance the soil fertility. 2. The biodegradable substances mainly contain carbon. These substances after decomposRead more
Biodegradable substances affect the environment by:
1. The biodegradable substances such as tree leaves, plant parts, and kitchen wastes can be used as humus after composting. This will enhance the soil fertility.
2. The biodegradable substances mainly contain carbon. These substances after decomposition release that carbon back into the atmosphere.
Substances are classified as biodegradable and non-biodegradable because some substances can be decomposed by microorganisms and some cannot. Substances that are broken down into simple soluble forms are called biodegradable substances and the substances that are not decomposed by microorganisms intRead more
Substances are classified as biodegradable and non-biodegradable because some substances can be decomposed by microorganisms and some cannot.
Substances that are broken down into simple soluble forms are called biodegradable substances and the substances that are not decomposed by microorganisms into harmless substances are called non biodegradable substances.
Why are we looking at alternate sources of energy?
