Greenhouse Effect

Hello everyone,today we will discuss the most important topic of a climate change. Before we dig deep into this it is important for us to know the basic meaning of greenhouse effect. We all must heard this word during any debate of global warming.
The light that we get from the sun helps to keep the planet warm.Out of the 100% light,almost 30% sunlight is reflected back into space by clouds,snow,ice,sand and other reflective surfaces. About 70% of the sunlight is absorbed by the ocean,land and the atmosphere.
The heat produced by the sunlight is in the form of Infrared Radiation before it enters into earth it all absorbed by the greenhouse gases present in the atmosphere. The absorption of the radiations by greenhouse gases make the temperature warm for human. Without greenhouse effect the planet would be lesser by 30 degree celsius and this would be too cold for us to survive.
The major greenhouse gases are carbon dioxide,ozone,methane and water vapor. Although these gases comprises 1% of our atmosphere,but the act like a thick warm blanket outside the planet and protect us from Infrared radiations.
Causes of greenhouse effect:-

  • Burning of fossil fuels.
  • Deforestation.
  • Increase in population.
  • Industrial waste and landfills.

Forests yes they are one of them,they are the heroes of the climate change story. I can say forests can be part of the solution. Forests and climate both are internally linked. The loss and degradation of forests effects the climate,they are the cause in reshaping the climate. But if we reduce this loss,we can reduce carbon emissions and we can have the multiple benefits for ecosystems and people. Now one question that arises is Can forests re-emerge as climate heroes? Yes forests plays a critical role in modifying the climate change. Every country must reserve their forest land and if we don't then it will increasingly pollute the atmosphere. Prince Charles stated that they are the world's air conditioning system-the lungs of the planets and we are on the border o...

The Recycle Story

Khalibottle has created an online platform where customers - individuals or corporates, can register for their waste to be collected for recycling. Once a request is raised for waste collection through a phone call or on their   website , a support team calls the customer and confirms the request. A pickup team arrives at their doorstep with a digital weighing scale and professional dress code, picks the trash and pays the customer as per the weight, through cash, coupons or the option to donate for a cause. The trash collected is segregated and packed according to predefined categories such as soft plastic, pet bottles, glass, cardboard materials, and metal. Finally, the stock is sent to authorised recycling plants around Bangalore, Mysuru, and Hyderabad through road or railways for recycling. Currently Khalibottle isoperates from two warehouses in North Bengaluru and collects waste from locations including Kammanahalli, Benson Town, Kalyan Nagar, Cox Town, Ramamurthy Naga...
