The world has started changing. There are many problems in our atmosphere and the main reason for this climate change in our atmosphere is ourselves. Majority of people really do not care about the earth. They think that everything will work as it should, but we are slowly losing our earth. We are letting many things go out of our hands. Majority of people know that there are many things that harm our atmosphere but all we see is carelessness and ignorance. The main reasons for climate changes are: mass production of goods, big factories that emit harmful smoke and gases, deforestation, maximum use of vehicles etc.
People have jobs and instead of using vehicles, this seems to be the major problem as the air pollution is resulting in this situation. Global warming has become a pressing issue in today's world, with impacts on the environment, ecosystem, and human societies. It refers to the long-term increase in the earth's average temperature due to the accumulation of greenhouse gases in the atmosphere. While natural factors play a role, human activities have emerged as the primary cause of global warming. Understanding these causes is essential in addressing the global challenge. Deforestation and land-use changes also contribute to the release of CO2, as forests play a crucial role in absorbing this greenhouse gas. Increased energy use and emissions are a result of the rapid rate of industrialisation and urbanization. Deforestation and the loss of carbon sinks are caused by the growth of cities and urban areas, which accelerates global warming. Deforestation upsets the balance by releasing carbon that has been stored and lowering the Earth's ability to absorb CO2. Additionally, Green House Gas emissions are also increased by soil erosion. Wide-ranging effects of global warming include dangers to human health and wellbeing, rising sea levels, extreme weather patterns, and damaged ecosystems. Human activities that produce greenhouse gases into the atmosphere are the main cause of global warming. Knowing these causes allows us to act as a community and implement long-term fixes. We can mitigate the effects of global warming, save our planet's ecosystems, and build a more sustainable future for future generations by adopting cleaner, more sustainable behaviors. To effectively address this global problem, there needs to be coordinated efforts at the individual, community, national, and international levels. The ozone layer was recovering during the lockdown due to lesser use of vehicles and other factories, but as soon as the lockdown was lifted, news broke that the hole had reopened. The hole needs to be sealed off because it helps protect us from ultraviolet (UV) radiation, which is harmful to humans.
