Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may
Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients. FIND OUT 5 WAYS HOW TO STOP POLLUTION. 2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth surface causing melting of polar ice caps, rise in sea levels and also flash floods, excessive snow or desertification. FIND OUT 5 WAYS HOW TO STOP GLOBAL WARMING. 3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food
Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natural causes as well. Recently, more intensive research has been done so that countries have the information they need to prevent acid rain and its dangerous effects. The levels of acid rain vary from region to region
integral to any approach. In some way or form, almost all cultures have recognized the importance of nature and its biological diversity for their societies and have therefore understood the need to maintain it. Yet, power, greed and politics have affected the precarious balance. Why Is Biodiversity Important? Who Cares? · Why is Biodiversity important? Does it really matter if there aren't so many species? · Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. · For example, a larger number of plant species means a greater variety of crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters. · And so, while we dominate this planet, we still need to preserve the diversity in wildlife.

GLOBAL WARMING Global warming is the observed century-scale rise in the average temperature of Earth's climate system. Since 1971, 90% of the increased energy has been stored in the oceans, mostly in the 0 to 700m region. Despite the oceans' dominant role in energy storage, the term "global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850. More than 90% certain that most of global warming was being caused by increasing concentrations of greenhouse gases produced by human activities.In 2010 that finding
Dear Sir/Madam, I am writing in the hope that you can help me with a problem regarding a camera that I have bought recently. On 24 April, I purchased a Canon digital SLR camera from a duty-free shop at Freetown Airport on my way from Freetown to Wondercity. The camera cost $599, and I paid for it by credit card. When I arrived at my hotel in Wondercity almost 24 hours later, I discovered that the box which contained the camera did not include the battery, and the space in the box for the charger was empty. I am now in Wondercity, and I am not returning to Freetown, so I need to get the missing parts here. I would be grateful if you could arrange for the parts to be sent to me. I attach a copy of the receipt for your information. I look forward to hearing from you. Yours faithfully, Introduction This report looks at the dietary habits of twenty students in their final year at Freedonian Secondary School
As time goes on, society will have to face many problems. The biggest issues are with the environment that is around us. It is surprising how our traditional habits can contribute so strongly to environmental problems. They affect the whole world, even our little country Estonia. We, as individuals, are capable of doing anything to save our world. To begin with, everyday life has been disturbed because of COVID-19. Life stopped during this pandemic not only in China where it started, but also across the globe. When we look at the present situation, very many people are confined to their own homes. In Estonia, students can’t go to school normally, they have to stay behind the computer every day and it is very exhausting. Many parents have lost their jobs because of the virus. And still there are people who won’t listen to the government rules and spread the virus further.
Environmental Problems and Sustainability The environment is our physical surroundings. This includes both human (man- made), social and physical (natural) features. Natural features include soil, the atmosphere, vegetation and wildlife. Human features include things such as culture, language and political systems. Geographers are concerned about human action in the environment. Human interference with the environment causes problems such as soil erosion, global warming and acid. You may ask how we as individuals can have an impact on the environment. Our actions can help to increase the problems highlighted above. For example turning off lights that are not being used helps to reduce global warming. Until recently, concern about the environment revolved almost exclusively around local and national problems. Over the past two decades, however, scientists have increasingly focused attention on more far-reaching environmental threats, such as
