Coal and Petroleum
In India, approximately 80% of the population relies on biomass fuels such as wood and dung for cooking and heating. However, the availability of these resources is not sustainable over a long period of time. The increasing demand for natural gas and oil has led to an increased use of coal and petroleum in India.
Coal is the most polluting fuel, releasing more than 26 million tons of CO2 annually into the atmosphere. This pollution affects both human health and the environment. Petroleum releases even more CO2 into the atmosphere than coal, but it also has significant environmental impacts due to its extraction process.
Both coal and petroleum are used extensively in India because they are relatively affordable sources of energy.

Reproduction in Animals
Every single animal on this planet is capable of reproducing. Reproduction in animals can be divided into two categories: sexual reproduction and asexual reproduction. Sexual reproduction happens when two gametes (the reproductive cells) unite to create a new individual. This process is called fertilization. Fertilization normally takes place in the female’s body during ovulation, but it can also happen outside the body during cross-pollination. The resulting zygote then grows into an embryo, which eventually becomes a baby animal.
Asexual reproduction doesn’t involve any gametes forming and isn’t limited to just plants and animals; viruses and even some bacteria are examples of asexual organisms. In asexual reproduction, the parent cell divides without making any new copies of itself. This process is how new genetic material is added to an organism’s DNA pool and passed down through generations.
It describes the modes and procedures of reproduction in animals. It is critical for the survival of a species. In this chapter, you will learn about the process of reproduction in animals in great detail.

Science is an important part of education, and one of the ways it is taught are through texts that cover a wide range of topics. One such text is the NCERT textbook for Class 8, which includes chapters on light. In this article, we will go over some key points about light that students must understand in order to learn from the text.
First and foremost, light is a type of energy that travels through the air or any other medium. It can be seen and photographed, but it can also be heard and felt as heat. Secondly, light consists of tiny particles called photons that travel at the speed of light. This means that they cannot be stopped or changed in any way by anything we could throw at them. Thirdly, when invisible light waves pass through a material like glass or water, they cause these materials to change their properties (like transparency).
Light discusses the fundamental properties, effects, and applications of light and its subordinates. This chapter also discusses regular reflection, diffused reflection, reflection laws, and other topics.

Pollution of Air and Water
Pollution of air and water is a major problem globally. It has serious consequences for human health, the environment, and industries. The National Curriculum-Elementary Science textbook “Earth’s Living Systems” uses recent science to explain how pollutants enter our atmosphere and water, and how they affect us.
According to the textbook, pollutants come from many different sources. Some pollutants are made by humans while others are produced naturally by plants or animals. Pollutants can be released into the air or water in several ways: through manufacturing processes, transportation, burning fuels, or through natural processes like rain or snowfall.
Once pollutants reach our atmosphere or water, they can be spread around the globe by wind or water currents. These substances can then cause serious damage to people, plants, and animals alike.
This chapter addresses the solution to the hazardous wonder of pollution and how one can contribute to its reduction in the individual dimension. This chapter talks about some of the most important things, air pollution and how air gets dirty. Ramsar Sites in India
