0 00:00:00,000 --> 00:00:13,000 What is acid rain? 1 00:00:13,000 --> 00:00:19,000 Acid rain is a type of precipitation that contains high levels of acidic components such as sulfuric 2 00:00:19,000 --> 00:00:20,000 and nitric acid. 3 00:00:20,000 --> 00:00:24,000 It's formed when the emissions from human activities such as burning fossil fuels mix 4 00:00:24,000 --> 00:00:25,000 with water in the atmosphere. 5 00:00:25,000 --> 00:00:30,000 This creates a chemical reaction that results in the formation of acidic compounds in the 6 00:00:30,000 --> 00:00:31,000 air. 7 00:00:31,000 --> 00:00:35,000 These compounds are then carried by the wind, and deposit onto the air's surface through 8 00:00:35,000 --> 00:00:38,000 precipitation such as rain, snow and fog. 9 00:00:38,000 --> 00:00:41,000 Acid rain in Madrid 10 00:00:41,000 --> 00:00:45,000 The gases that produce acid rain are mainly sulfur dioxide and nitrogen oxide. 11 00:00:45,000 --> 00:00:49,000 In Madrid, these gases are largely produced by vehicles and factories. 12 00:00:49,000 --> 00:00:54,000 According to a study conducted by the Spanish Ministry for Ecological Transition and Demographic 13 00:00:54,000 --> 00:01:00,000 Challenge in 2020, Madrid has some of the highest levels of air pollution in Europe. 14 00:01:00,000 --> 00:01:03,000 And acid rain is a major contributor to this problem. 15 00:01:03,000 --> 00:01:08,000 This can lead to serious health problems such as respiratory illnesses and heart diseases. 16 00:01:08,000 --> 00:01:11,000 Defects of fauna and flora 17 00:01:11,000 --> 00:01:14,000 Defects of acid rain on vegetation can be severe. 18 00:01:14,000 --> 00:01:19,000 It damages leaves and stunts plant growth, making it difficult for forests and other 19 00:01:19,000 --> 00:01:21,000 plant communities to thrive. 20 00:01:21,000 --> 00:01:26,000 Acid rain can also have harmful effects on animals that rely on these plants for food 21 00:01:26,000 --> 00:01:27,000 and habitat. 22 00:01:27,000 --> 00:01:33,000 Additionally, acid rain can lead to the acidification of bodies of water, such as lakes and rivers, 23 00:01:33,000 --> 00:01:35,000 which can kill fish and other aquatic life. 24 00:01:35,000 --> 00:01:41,000 Acid rain can also damage buildings, statues and monuments made of limestone or marble. 25 00:01:41,000 --> 00:01:44,000 Guadarrama mountains 26 00:01:44,000 --> 00:01:48,000 The Guadarrama mountains in Spain have been particularly affected by acid rain. 27 00:01:48,000 --> 00:01:53,000 The acid rain damages the soil and makes it difficult for plants to absorb nutrients, 28 00:01:53,000 --> 00:01:57,000 which can lead to the death of trees and other vegetation. 29 00:01:57,000 --> 00:02:02,000 This can have a ripple effect on the entire ecosystem, impacting everything from water 30 00:02:02,000 --> 00:02:05,000 quality to wildfire population. 31 00:02:05,000 --> 00:02:11,000 The Spanish government has implemented measures to reduce emissions, such as promoting the 32 00:02:11,000 --> 00:02:15,000 use of renewable energies or investing in public transport. 33 00:02:16,000 --> 00:02:18,000 Our social media 34 00:02:18,000 --> 00:02:24,000 We have created social networks in order to spread awareness of what we are doing to share 35 00:02:24,000 --> 00:02:25,000 all our projects. 36 00:02:25,000 --> 00:02:29,000 We have created a webpage and accounts in all social media platforms. 37 00:02:29,000 --> 00:02:35,000 Adding to this, we have done a lot of experiments and collected a lot of information that is 38 00:02:35,000 --> 00:02:37,000 available on our webpage. 39 00:02:37,000 --> 00:02:40,000 Avoid acid rain negative effects 40 00:02:40,000 --> 00:02:42,000 So, what can we do to avoid it? 41 00:02:43,000 --> 00:02:48,000 Well, the most important part when fighting acid rain is to reduce as much as possible 42 00:02:48,000 --> 00:02:52,000 the use of fossil fuels, both in cars and factories. 43 00:02:52,000 --> 00:02:57,000 For this, we think that renewable energies should be more used.
