Abstract Global warming is how scientists describe the gradual warming of our global climate. Scientists think that the trend towards global warming can be attributed to the build up of greenhouse gases in the earth's atmosphere from industrialization. Another problem is deforestation, as we remove plants and trees from the environment to meet a high demand for lumber or by clear cutting fields for farming and urbanization. By removing trees from the earth's environment, are we changing how greenhouse gasses are processed in the earth's atmosphere? What effect do trees and plants have on greenhouse gases? You can perform an experiment using miniature greenhouse pickle jars to test the effect of plants on greenhouse gases. Place a plant in one jar, and leave the other jar empty. Place a thermometer in each jar and put the jars in a sunny window. Record the temperatures, which jar is the warmest? Are there other variables you can test?

Career Focus

If you like this project, you might enjoy exploring related careers.

	Agricultural Technician As the world's population grows larger, it is important to improve the quality and yield of food crops and animal food sources. Agricultural technicians work in the forefront of this very important research area by helping scientists conduct novel experiments. If you would like to combine technology with the desire to see things grow, then read further to learn more about this exciting career.			Plant Scientist With a growing world population, making sure that there is enough food for everyone is critical. Plant scientists work to ensure that agricultural practices result in an abundance of nutritious food in a sustainable and environmentally friendly manner.
	Climate Change Analyst How is climate change affecting Earth? What will the changes mean for society? If these are questions that peak your curiosity, then you might be interested in a job as a climate change analyst. Climate change analysts evaluate climate data and research to determine how shifts in the climate will affect natural resources, animals, and civilizations. They use this information to make suggestions about what individuals and governments can do to ensure a higher-quality life for everyone in the face of a changing environment.			Environmental Scientist Have you ever noticed that for people with asthma it can sometimes be especially hard to breathe in the middle of a busy city? One reason for this is the exhaust from vehicles. Cars, buses, and motorcycles add pollution to our air, which affects our health. But can pollution impact more than our health? Cutting down trees, or deforestation, can contribute to erosion, which carries off valuable topsoil. But can erosion alter more than the condition of the soil? How does an oil spill harm fish and aquatic plants? How does a population of animals interact with its environment? These are questions that environmental scientists study and try to find answers to. They conduct research or perform investigations to identify and eliminate the sources of pollution or hazards that damage either the environment or human and animal health. Environmental scientists are the stewards of our environment and are committed to keeping it safe for future generations.
