INTRODUCTION

In this activity we will see what are the main environmental problems that occur in our city (Monterrey N.L).

Problems such as pollution, caused mainly by the industrial sector, as our city is characterized by the industry and the consequences they bring these, such as: waste of toxic substances in rivers, which results in many fish die or the same substances thrown into rivers are a key factor in today climate change this radically.

In addition a number of statistics show (graphic) on the main changes I been on climate change in recent years, also we show some interviews with researchers on these environmental problems, showing us his position on this issue.

Finally you meet our general idea and possible solutions to these respects environmental problems, about what investigated (information, statistics, interviews, etc.) so that you have a clearer idea on this issue and so can provide solutions.

Major Current Environmental Problems

Pollution: Pollution of air, water and soil require millions of years to recoup. 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 combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.[pic 4]

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 unnatural patterns of precipitation such as flash floods, excessive snow or desertification.

Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial purpose.[pic 6]

Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known  environmental problem that can have serious effect on human health, wildlife and aquatic species. [pic 7]

What is air pollution?

Air is polluted when it contains any extraneous entity in sufficient quantities to adversely affect the environment or the health of people exposed to it.

How is air pollution measured?

Air pollution is often measured as the mass of a pollutant per volume of air, which is a concentration. Concentrations in a particular location depend on many factors, including activity from local emission sources, the transport of pollution from distant sources to the location where the concentration is being measured, weather and land patterns. There are many different instruments and techniques to measure air pollution.

What level of air pollution is present in the UK and how does this compare to other countries?

Of the pollutants commonly measured in the UK, the most health relevant is PM2.5. Average levels of PM2.5 outdoors in areas where most of the population lives is about 10 micrograms/m3.Levels in large metropolitan areas are higher: average PM2.5 in London is approximately 14 micrograms/m3. Annual average PM2.5 levels in most large cities across the globe are above the World Health Organization guideline of 10 micrograms/m3. In many cities in low and middle-income countries, PM2.5 levels are several times higher than this guideline. During air pollution episodes, concentrations over a few days to weeks can be much higher; hundreds of micrograms/m3 is not uncommon.
