NUMBER 2 NUMBER 3 Eleni D.-Greece YoungAction for YouropeVision Water Pollution From big pieces of garbage to invisible chemicals, a wide range of pollutants ends up in our planet's lakes, rivers, streams, groundwater, and eventually the oceans. Water pollution has contributed to a freshwater crisis, threatening the sources we rely on for drinking water and other critical needs.Water pollution can come from a variety of sources. Pollution can enter water directly, through both legal and illegal discharges from factories, for example, or imperfect water treatment plants.Water pollution can result in human health problems, poisoned wildlife, and longterm ecosystem damage. Solutions: 1. Discourage firms and people from disposing their trash in rivers, lakes or oceans 2. Replace fossil fuels by renewable energies 3. Reduce plastic-water waste 4. Do not pour fat from cooking or any other type of fat and oil down the sink. 5. Avoid using household chemicals or cleaning agents down the sink or toilet Global Warming On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases. If this situation continues, Earth will become warmer. Some regions may welcome warmer temperatures, but others may not. Also, a stronger greenhouse effect will warm the oceans and partially melt glaciers and other ice, increasing sea level. And finally, warmer situation cause evaporation, as a result some regions become dryer and others wetter. 20
