Global Warming
A common topic known worldwide as controversial and challenging is global warming. Many people do not know the cause and effect between man-made activities, practices, and behaviors that have contributed significantly to global warming. All nations should be required by law to curtail, modify, or stop such activity. A great difference in climate change will occur if people around the world became aware of their actions to achieve a more stable and safer environment.    Scientists have spent many years trying to figure out what is causing global warming. They have looked at the natural cycles and events that are known to influence climate. “The amount and pattern of warming that's been measured can't be explained by these factors alone.” Realizations of scientists have concluded that humans contribute to the earth’s temperature getting warmer. Greenhouse gases produce by humans, are responsible for global warming, most of which come from the combustion of fuels in cars, factories, and electricity production. Some of these gasses can trap more heat within the world then carbon dioxide (“Climate Hot Map”). Carbon dioxide lives in the atmosphere for a long time, up to centuries, so its heat-trapping effects are accumulated over time. This type of gas can put the world at a great risk of catastrophic changes if it continues to accumulate unabated in the atmosphere. Land and ocean temperature is only one way to measure the effects of climate change. “A warming world also has the potential to change rainfall and snow patterns, increase droughts and severe storms; reduce lake ice cover, melt glaciers, increase sea levels, and change plant and animal behavior.” (“Climate Hot Map”). When people litter, animals suffer. Many animals are injured, become ill, and die each year due to human carelessness with litter and pollution. Animals can swallow or get entangled in many of the litter items people leave in the environment. For example they can eat it and it could do damage to their intestinal tract by causing a blockage. Then they would die a slow and painful death. The animals also can also ingest toxic substances like motor oil and pesticides, which are often dumped into storm drains and end up in our earth’s waterways. Plastic bags account for over ten percent of the debris washed up on the U.S. coastline. Over time they break down into smaller more toxic polymers, and they eventually contaminate soil and the waterways. As a consequence, microscopic particles can enter the food chain. Nearly two hundred species of the sea life including whales, seals, turtles and dolphins die due to plastic bags. Most plants and animals live in areas with very specific climate conditions, such as temperature and rainfall patterns, that enable them to thrive. ” If we used cloth bags we can save six bags a week, twenty four every month, which is two hundred eighty eight a year.” (‘Pocono Green’).   There are many different things people can do to prevent global warming. By choosing reusable products instead of disposables will help to reduce waste.” Adding insulation to walls and attic, and installing weather stripping or caulking around doors and windows can lower heating costs more than 25 percent, by reducing the amount of energy needs to heat and cool your home. Saving electricity can reduce global warming by turning off lights when you leave a room, and using only as much lights as you need” (Esseck).    If more trees were planted in places where humans have destroyed forests more oxygen is would be given off.  During photosynthesis, trees and other plants absorb carbon dioxide which is a greenhouse gas and give off oxygen. There are not enough trees to fully battle the amount of carbon dioxide being admitted into the air. A single tree will absorb approximately one ton of carbon dioxide during its lifetime. The increasing temperatures can disrupt the wildlife. Climate change has altered food availability for migrating species....
