The experience that came from the multiple field trips we went on was extremely beneficial and a great life experience. Within all three field trips‚ we surveyed freshwater and saltwater fish and identified their species. We had two trips to the Mead Gardens and one trip to the Florida Keys. To survey the fish‚ we used multiple fish catching techniques. In the Mead Gardens‚ to catch fishes‚ we used two separate types of fish traps. Furthermore‚ in the Florida Keys‚ we caught fish with a gill net

Water Runs Dry – North American Water Crisis Collectively the United States is ranked as the greatest consumers of water worldwide; a startling fact for a country that cannot support its own unrivaled demands (Barlow‚ 2007). The United States is now crucially dependent on nonrenewable groundwater for a staggering 50% of its daily water usage (Barlow‚ 2007). In addition to such formidable numbers‚ citizens of the United States use and waste up 80-100 gallons or 454 liters of water per day (Perlman

What’s more‚ water and populations are unevenly distributed across the globe; arid and semi-arid regions receive only two percent of all surface runoff yet account for 40 percent of the global land area and house half of the world’s poor. Finally‚ our existing freshwater resources are under heavy threat from overexploitation‚ pollution‚ and

But the reality we face is sobering: water -- nature’s most essential element -- is becoming dangerously scarce. A freshwater crisis has already begun that threatens to leave much of the world dry in the next 20 years‚ without enough water for a minimum of life. Nearly 2.2 billion people in more than 62 countries‚ one-third of the world’s population‚ are starved
