Pollution of Air and Water
Prepare a brief speech on global warming. You have to deliver the speech in your class.
The radiations that fall on the earth’s surface are trapped by the atmosphere just like a greenhouse where the heat is trapped inside a nursery and is not allowed to move out. These trapped rays warm the Earth's surface. This is known as the greenhouse effect. The increasing amount of CO2 leads to the greenhouse effect. We know that human releases carbon dioxide while respiring. Since the population is increasing the amount of CO2 is increasing at an alarming rate. Along with big factories and industries are releasing carbon dioxide into the air. As plants consume carbon dioxide while photosynthesis but nowadays there is little space left for forests. As a result, the amount of carbon dioxide is increasing in the atmosphere. This CO2 traps the heat and does not let it escape. This thereby increases the temperature of the Earth. This is known as Global warming. Global warming is a major threat to the environment. It causes an increase in sea level drastically that causes floods in many coastal areas. It widely changes the pattern of rainfall that could adversely affect the people who depend on agriculture as the source of income. It has become a major threat worldwide. Many countries started working on reducing carbon dioxide gas emissions. The Kyoto Protocol is the agreement between some countries that work together to reduce the emission of xi major greenhouse gases.

What our students and parents say about us!
Saiyam is using EduSaksham online courses from past one year. He is able to complete his tutorials, worksheets, and assignments on his own. Once he is done with worksheets, he can check his answers and if he has done any mistakes, then he can check the correct answers and explanations. They have been given so well that he is able to understand them himself and rarely he asks us for any clarification. He enjoys using the platform and has learned and improved a lot in Mathematics. I would recommend EduSaksham to all parents who want their kids to learn in a structured way and also enjoy the learning process.
Neeraj (Saiyam's Father)
I would like to thank Edusaksham on behalf of my son Aditya who attended " Math Olympiad crash course for 5 weeks". As per Aditya, this course helped him to understand new topics like Roman numerals and decimal places which were not taught in his school till date and had a better understanding of other topics. I personally thank EduSaksham for all the help and support.
Geeta Bansal (Aditya's Mother)
We had a good experience with EduSaksham. Because sheets are available online, Vedant enjoyed doing more and more sheets without any reminders. I could leave him on his own as he was very much motivated to cover the topics. Practice is very important in maths but it becomes difficult for us to prepare sheets, I am glad we found EduSaksham where in a lot of in a lot of sheets are available for practice and the quality of questions are also good. As it's a venture from IITians we could think of giving it a try and I am glad we tried
Shikha Chowdhary (Vedant's Mother)
I have grown up in a family where my father used to give me practice maths paper every day which I need to finish before I go to play. I think that strong foundation of solving new questions every day helped me to clear my IITJEE exam. But as working women, I always had time challenge to create practice Math papers for my daughter. Thanks to EduSaksham, their questions are so logical and conceptual that I don't feel the guilt of not creating practice questions by myself :). There are plenty of worksheet along with the tutorials for each chapter. It has made parents life easier :) And the best part is my daughter loves doing it. Thank you EduSaksham.
